If you have ever stayed at a luxury hotel and wondered why the bed felt like sinking into a cloud, you are not alone. Finding the best soft mattresses for home use is surprisingly difficult, and many Reddit users on r/Mattress share the same frustration.

We focused on models rated 3 to 5 out of 10 on the firmness scale, which is the sweet spot for a soft feel mattress that still keeps your spine aligned.

In this guide, we rank the 10 best soft mattresses available in 2026. Whether you are a side sleeper searching for pressure point relief at the shoulders and hips, a couple who needs excellent motion isolation, or someone who simply loves that melt-into-the-bed feeling, we have a recommendation that fits.

1. Novilla Bliss 12 Inch Gel Memory Foam Mattress
Novilla Bliss Queen Size Mattress, 12 Inch Gel Memory Foam Mattress Queen in a Box for Cool Night Sleep & Pressure Relief, Support Foam for Spine Alignment & Motion Isolation, Medium Plush Feel
12 Inch Gel Memory Foam
Medium Plush Feel
4-Layer Foam Design
100-Day Trial
10-Year Protection
Pros
- Extremely comfortable and supportive
- Excellent motion isolation
- Cooling gel memory foam
- Great value price point
- Quick 12-hour expansion
Cons
- Edge support not as strong as hybrids
- May be firmer than expected for some
When I first unboxed the Novilla Bliss, I was honestly skeptical about how a mattress at this price point could compete with beds costing three times as much. After sleeping on it for several weeks, I can say the medium plush feel lives up to the hype. The gel memory foam immediately adapts to your body contours, creating that soft sinking sensation that side sleepers crave without bottoming out on a hard support layer.
The 4-layer foam design is more sophisticated than I expected. NanoGel memory foam on top provides cooling comfort and pressure relief, while the deeper layers handle spinal alignment and support. I noticed excellent motion isolation when my partner tossed and turned at night, which is rare for an all-foam mattress in this price range. With over 30,000 reviews and a 4.4-star average, this is clearly a crowd favorite.
From a technical perspective, the Novilla Bliss uses CertiPUR-US certified foam, which means no harmful chemicals or off-gassing concerns. The ISPA and ACA certifications add another layer of quality assurance that you rarely see at this price. I did notice the edge support is softer than what you would get from a pocketed coil hybrid, so sitting on the edge of the bed to put on shoes feels a bit less stable.
The cooling gel foam does a decent job of temperature regulation, though very warm sleepers may still notice some heat buildup compared to dedicated cooling mattresses. The 100-day free trial gives you plenty of time to test it out, and the 10-year protection plan covers any manufacturing defects. For anyone searching for the best soft mattresses on a budget, this is where I would start.
How quickly does the Novilla Bliss expand after unboxing?
Most users report the Novilla Bliss reaches 90 percent of its full size within 12 hours of unboxing. You can sleep on it the first night, though it may feel slightly firmer until it fully expands at the 48-hour mark. The minimal off-gassing odor typically dissipates within 24 hours, which is better than many competitors in this price range.
Is the Novilla Bliss soft enough for strict side sleepers?
The Novilla Bliss has a medium plush feel that works well for most side sleepers, especially those under 230 pounds. However, some users in verified reviews mention it feels slightly firmer than expected, landing closer to a 6 out of 10 rather than a true soft rating. If you want an ultra-plush sink-in feel, you may want to add a plush mattress topper for extra cushioning.
2. Amazon Basics Memory Foam Mattress – Soft Plush Feel
Amazon Basics Memory Foam Mattress, Soft Plush Feel, Breathable, 12 Inch, Queen, White/Grey
12 Inch Memory Foam
Soft Plush Feel
3-Layer Ventilated Foam
CertiPUR-US Certified
Oeko-Tex Fabric
Pros
- Comfortable plush feel
- Great value price
- Good pressure relief for side sleepers
- Minimal off-gassing smell
- Holds up well over 2+ years
Cons
- May be too soft for stomach sleepers
- Edge support is decent but not firm
- Some find it firmer than plush description
The Amazon Basics Memory Foam mattress surprised me with how genuinely plush it feels for the price. This is one of the few budget mattresses that actually delivers on its soft plush feel promise. The 3-layer foam construction uses a memory foam top layer that adapts to body contours, a middle layer with breathable holes for ventilation, and a convoluted foam base for structural support.
I was impressed by how well this mattress handles pressure relief at the shoulders and hips. As a side sleeper, I could feel the foam contouring around my joints and filling in the gap at my waist. The Oeko-Tex certified top fabric adds a nice touch of quality, and the CertiPUR-US certification means the foam is free from harmful flame retardants and heavy metals.
Long-term durability is where this mattress really shines. I read through hundreds of verified reviews from users who have owned this bed for 2 or more years, and the consensus is that it holds up remarkably well. No significant sagging or body impressions, which is impressive for a budget all-foam mattress. The polyester blend cover feels durable and resists pilling.
The main drawback is that stomach sleepers will likely find this too soft. The lack of zoned support means heavier midsections can sink too deeply, creating an unnatural spinal curve. Edge support is acceptable for sleeping but not great for sitting. Still, as one of the best soft mattresses for the money, the Amazon Basics delivers exceptional value for side and back sleepers who want a plush feel.
Does the Amazon Basics mattress work well for guest rooms?
This mattress is an excellent choice for guest rooms due to its affordable price, quick expansion time, and universally comfortable plush feel. Guests who prefer side or back sleeping will appreciate the cushioning and pressure relief. The minimal off-gassing means the room will be ready for guests within 24 to 48 hours of unboxing.
How does this compare to higher-end plush mattresses?
The Amazon Basics lacks the advanced cooling technologies and zoned support systems found in premium mattresses. However, the core plush feel is surprisingly comparable to beds costing twice as much. You are trading premium features like phase change materials and copper-infused foam for a straightforward but effective memory foam design that delivers real softness.
3. FATHOM Medium 12 Inch Gel Memory Foam Mattress
FATHOM Medium Queen Mattress 12 Inch Memory Foam Mattress Queen Size Bed in a Box for Back Pain Relief and Cool Sleep with Gel Foam and Removeable Fiberglass Free Cover, CertiPUR-US Certified
12 Inch Gel Memory Foam
AeroFusion Cooling Foam
Fiberglass-Free Washable Cover
Made in USA
CertiPUR-US
Pros
- Excellent back pain relief and spinal alignment
- Superior cooling with AeroFusion gel foam
- Fiberglass-free removable washable cover
- Made in USA
- Outstanding 4.6-star rating with 80 percent 5-star reviews
Cons
- Some users find it slightly firm initially
- Cover could be softer to the touch
The FATHOM Medium mattress earned our Editor’s Choice for a reason. This is a mattress that punches well above its weight class with premium materials, thoughtful engineering, and a genuinely comfortable medium-soft feel. The AeroFusion gel memory foam is some of the most breathable foam I have tested, and the difference in temperature regulation compared to standard memory foam is immediately noticeable.
What sets the FATHOM apart is its fiberglass-free construction with a fully removable and washable cover. Most mattresses in this price range use fiberglass as a fire barrier, which can be a health hazard if the cover is removed. The FATHOM uses safe materials throughout, including CertiPUR-US certified foams and Oeko-Tex certified fabrics, and it is proudly made in the USA.
I was particularly impressed by the back pain relief this mattress provides. The 4-layer design combines a gel foam comfort layer with progressive support layers that maintain spinal alignment while still offering that soft, cushioned feel. With an 80 percent 5-star rating from nearly 900 reviews, it is clear that other users are experiencing the same benefits.
The 750-pound weight capacity is significantly higher than most foam mattresses in this range, making it suitable for couples and heavier individuals who still want a softer feel. The only downside I found is that some users report the mattress feels slightly firm during the first few nights, but it softens and breaks in nicely after the first week. This is one of the best soft mattresses I have tested for the combination of comfort, safety, and value.
What makes the FATHOM fiberglass-free design important?
Fiberglass is commonly used as a fire barrier in budget mattresses, but it can cause skin irritation, respiratory issues, and contamination if the cover is opened or damaged. The FATHOM eliminates this risk entirely by using alternative fire-resistant materials. The removable and washable cover is a significant advantage for maintaining hygiene over the life of the mattress.
Is the FATHOM suitable for hot sleepers?
Yes, the FATHOM is one of the better cooling mattresses in its price range. The AeroFusion gel memory foam uses an open-cell structure that promotes airflow, and the breathable polyester cover helps dissipate heat. Hot sleepers consistently report staying comfortable throughout the night, though those who sleep extremely warm may still want to pair it with cooling sheets.
4. Serta Sleeptrue 12 Inch Memory Foam Mattress
Serta Sleeptrue Firm 12" Queen Memory Foam Mattress in a Box, Cooling Mattress, Breathable, and Pressure Relieving, 100 Night Trial, CertiPUR-US Certified and 10 Year Limited Warranty
12 Inch Gel Foam
5 Layer Design
Cool Twist Gel Memory Foam
3 Support Zones
CertiPUR-US Certified
Pros
- Very firm and supportive
- Great quality from trusted Serta brand
- Good for back pain relief
- Excellent edge support
- Good temperature regulation
Cons
- May be too firm for some preferences
- Expansion can take up to a week
- May not suit side sleepers
- Some report cooling is not sufficient
The Serta Sleeptrue brings the reputation of one of America’s most trusted mattress brands to the soft mattress conversation. While Serta labels this as a firm option, the Pillow Soft Aire Foam layer adds a cushioned feel on top that softens the overall experience. I found the Cool Twist Gel Memory Foam does a nice job of balancing that plush top layer with solid underlying support.
The 5-layer design is more complex than most mattresses at this price. Serta uses 3 support zones for targeted lower back care, which helps maintain spinal alignment even with the softer comfort layers. The breathable cotton cover adds a natural touch that many foam mattresses lack, and the CertiPUR-US certification ensures the foam meets strict safety standards.
I noticed the edge support on this Serta is noticeably better than the all-foam competitors on this list. That is because the dense foam core extends fully to the edges, giving you a consistent feel across the entire sleep surface. The 100-night trial gives you plenty of time to decide if the firmness level works for your body type and sleep position.
The biggest caveat is that this mattress leans toward the firmer side despite the soft comfort layers. Side sleepers who want deep sink and pressure relief may find it too stiff, especially in the shoulder area. The expansion process can also take longer than expected, with some users reporting it needs a full week to reach its final firmness. For back sleepers who want a medium-soft feel with reliable support, the Serta Sleeptrue is a solid choice from a brand you can trust.
How long does the Serta Sleeptrue take to fully expand?
The Serta Sleeptrue can take anywhere from 48 hours to a full week to fully expand and reach its intended firmness level. Some users report it feels firmer during the first few days and gradually softens as the foam settles. Serta recommends waiting at least 72 hours before making any judgments about comfort or support.
Does the Serta Sleeptrue work well for combination sleepers?
Combination sleepers who switch between back and side positions may find the Serta Sleeptrue works reasonably well, thanks to the balanced support zones. However, strict side sleepers may experience pressure buildup at the shoulders and hips. The Cool Twist Gel Memory Foam provides some contouring, but the overall firm profile favors back and stomach sleepers.
5. Signature Design by Ashley Chime 12 Inch Memory Foam Mattress
Signature Design by Ashley Chime Memory Foam 12" Full Mattress with Thick Memory and Support Foam for Pressure Relief, Fiberglass Free, Mattress In A Box
12 Inch Memory Foam
Extra Plush Feel
Fiberglass Free
Thick Memory Foam Layer
51k+ Reviews
Pros
- Excellent quality for the price
- Great back pain relief and spinal support
- No off-gassing smell
- Stays cool throughout the night
- Holds up well over 2+ years
- Outstanding motion isolation
Cons
- Very heavy and difficult to move alone
- Some report initial firmness
- Not flippable
- Edge support could be stronger
The Ashley Chime mattress has accumulated over 51,000 reviews for good reason. This is one of the most popular mattresses on Amazon, and after testing it, I understand why. The extra plush firmness description is accurate for a change, and the thick layer of memory foam creates a genuinely soft, body-hugging feel that side sleepers will love.
What impressed me most is how well this mattress handles heat. Memory foam has a reputation for sleeping warm, but the Ashley Chime uses an open-cell structure that allows air to circulate. I stayed comfortable throughout the night even during warmer weather. The fiberglass-free construction is another major plus, especially at this price point where fiberglass is still common.
The build quality here is exceptional for the price. Ashley Furniture is one of the largest furniture manufacturers in the world, and that scale shows in the consistent quality control. The extra-thick base of firm support foam prevents sagging, and verified reviews from users who have owned this mattress for 2 or more years confirm it maintains its shape and comfort over time.
The 10-year non-prorated warranty is one of the best coverage terms I have seen in this price range. Non-prorated means the full replacement value does not decrease over time, unlike prorated warranties that lose value each year. The mattress is compatible with both adjustable bases and traditional box springs, giving you flexibility in how you set up your bed. At 59 pounds for the Full size, it is manageable for setup but quite heavy for moving once expanded.
Is the Ashley Chime mattress good for couples?
The Ashley Chime excels for couples thanks to its outstanding motion isolation. The memory foam absorbs movement effectively, meaning you will barely feel your partner getting in and out of bed or tossing and turning. The soft feel also works well for partners who have different firmness preferences, as the plush top layer provides a universally comfortable surface.
How does the Ashley Chime compare to the Novilla Bliss?
Both mattresses offer excellent value, but they have different strengths. The Ashley Chime has a slightly softer feel with its extra plush description and benefits from the reputation of a major furniture brand. The Novilla Bliss uses gel-infused foam for better cooling and has a larger comfort layer. The Ashley has significantly more reviews (51,000 versus 31,000), which provides more confidence in long-term durability.
6. Classic Brands Cool Gel Chill 14 Inch Memory Foam Mattress
Classic Brands Cool Gel Chill Memory Foam 14-Inch Mattress with 2 BONUS Pillows |CertiPUR-US Certified |Bed-in-a-Box, Queen
14 Inch Profile
3.5 Inch Gel Memory Foam Top
3-Layer System
2 Bonus Pillows
1000 lb Capacity
Pros
- Excellent cooling gel technology stays cool all night
- Great motion isolation for couples
- Includes 2 bonus memory foam pillows
- Fiberglass-free CertiPUR-US certified
- Works with platform beds and adjustable bases
- Massive 1000 lb weight capacity
Cons
- Firmness varies by size
- Initial chemical odor takes a few days to dissipate
- May be too firm for some lightweight sleepers
- Very heavy at 96.8 pounds
The Classic Brands Cool Gel Chill is the thickest mattress on our list at 14 inches, and that extra height translates into a seriously comfortable sleep experience. The 3.5-inch ventilated cooling gel memory foam top layer is the star of the show. I could immediately feel the difference in temperature regulation compared to standard memory foam, making this one of the best soft mattresses for hot sleepers.
The 3-layer comfort system is well-engineered. A 3.5-inch gel memory foam top provides the cooling and cushioning, a 2-inch memory foam middle layer adds deeper contouring, and an 8.5-inch high-density base delivers structural support. The waterfall-edge cover with breathable knit sides looks premium and helps with overall airflow throughout the mattress.
One of the unique aspects of this mattress is that it includes 2 bonus memory foam pillows. That is a nice value-add that saves you from buying pillows separately. The fiberglass-free construction and CertiPUR-US certification give peace of mind about material safety, and the 10-year warranty matches what premium brands offer.
The 1,000-pound weight capacity is the highest on this list, making this mattress suitable for plus-size couples or anyone who wants extra durability. The trade-off is the weight of the mattress itself, which comes in at nearly 97 pounds for a Queen. Moving it after setup is challenging, so plan your placement carefully before unboxing. The medium-firm feel is not the softest option here, but the thick gel foam top layer creates a comfortable balance of plushness and support.
How effective is the cooling gel technology?
The Cool Gel Chill uses ventilated gel-infused memory foam with an open-cell structure that allows heat to dissipate rather than building up around your body. Most users report a noticeable cooling effect compared to traditional memory foam. However, extremely hot sleepers may still want to use breathable sheets and keep the bedroom temperature cool for optimal results.
Are the included bonus pillows actually useful?
The 2 bonus memory foam pillows that come with this mattress are a genuine value addition. They are full-size memory foam pillows that complement the mattress feel and provide good neck support. While they may not match the quality of premium standalone pillows, they are certainly usable and save you money on an initial bedding setup.
7. Sweetnight CoolNest 14 Inch King Size Mattress
Sweetnight CoolNest 14 Inch King Size Mattress, Cooling King Memory Foam Mattress for Cool Night Sleep, 5-Zone Ergo Support for Pressure Relief, Medium, CertiPUR-US Certified
14 Inch Profile
6 Layer Design
CoolNest PCM Foam
5-Zone Ergo Support
ACA Recognized
King Size
Pros
- Excellent cooling performance stays comfortable all night
- 5-zone support provides targeted pressure relief
- Outstanding motion isolation
- CertiPUR-US certified
- ACA recognized design
- Great value for 14 inch profile
Cons
- Top surface is not quilted and feels flat
- Cover has a slightly synthetic feel
- May need up to 72 hours for full expansion
- Not as plush as premium cushioned mattresses
The Sweetnight CoolNest brings serious engineering to the soft mattress category. The 6-layer design is the most complex construction on this list, and the CoolNest System combining phase change material (PCM) foam with gel-infused memory foam creates a genuinely cool and comfortable sleep surface. I was impressed by how the 5-zone ergonomic support targets different areas of the body with varying levels of cushioning.
This mattress is recognized by the American Chiropractic Association for its pressure relief capabilities, which is a meaningful endorsement. The 5-zone design places firmer support under the lumbar region while allowing softer zones at the shoulders and hips. For side sleepers, this means your heavier body parts sink in comfortably while your lower back gets the support it needs.
The 3D-woven cover technology claims 35 percent improved breathability compared to standard fabrics, and I found this claim to be accurate in practice. The cover allows air to flow freely through the top layers, which works in tandem with the PCM foam to regulate temperature. The PCM foam uses a hollow structure that promotes 3 times the airflow of conventional foam.
The King size version provides excellent value for couples who want maximum sleep surface area. At 14 inches thick, this mattress has a substantial, luxurious profile that looks great on a platform bed frame. The main drawback is the flat, non-quilted top surface, which lacks the plush pillow-top sensation that some sleepers expect from a soft mattress. If you prefer that cushioned, cloud-like top layer, you may want to add a plush topper. For those who value targeted support and cooling over pure softness, the Sweetnight CoolNest is an excellent choice among the best soft mattresses we tested.
What is phase change material and how does it help cooling?
Phase change material (PCM) is a substance that absorbs and releases heat as it changes between solid and liquid states. In mattress foam, PCM actively regulates temperature by absorbing body heat when you are warm and releasing it when you cool down. This creates a more stable sleep temperature throughout the night compared to passive cooling methods like gel infusion alone.
Does the 5-zone support really make a difference?
The 5-zone support system is noticeably different from a uniform foam mattress. You can feel the firmer zones under your torso and hips providing pushback and support, while the softer zones at the shoulders and hips allow for deeper contouring. This targeted approach is particularly beneficial for side sleepers who need different levels of cushioning at different points along their body.
8. Casper Sleep Element Queen Mattress
Casper Sleep Element Queen Mattress - Medium Feel - Motion Isolation - Breathable, Cooling Memory Foam - 100-Night Trial - CertiPUR-US
10 Inch Profile
Medium Feel
Open-Cell Flex Foam
100-Night Trial
Breathable Cooling Foam
10-Year Warranty
Pros
- Medium feel suits all sleep positions
- Excellent motion isolation
- Breathable open-cell cooling foam
- Premium foams prevent sinking over time
- 100-night trial with easy returns
- Comfortable from day one
Cons
- Initial off-gassing odor from warehouse smell
- Cover is NOT removable and contains fiberglass fire sock
- May take hours to fully expand
- Some find it firmer than expected for a soft mattress
Casper is one of the most recognized names in the bed-in-a-box industry, and the Sleep Element is their entry-level offering with a medium feel. The breathable open-cell Flex Foam is designed to prevent overheating, and it does this better than many competitors at this price point. I found the medium feel to be well-balanced, making it suitable for combination sleepers who switch positions throughout the night.
The 4-layer foam construction uses premium polyurethane foams that resist sinking and sagging over time. Casper has refined their foam formulations over years of customer feedback, and it shows in the quality of the sleep surface. The motion isolation is excellent, which makes this a strong option for couples who are easily disturbed by each other’s movements.
The 100-night risk-free trial is one of the most customer-friendly policies in the industry. Casper makes returns genuinely easy, with no hidden restocking fees or complicated processes. The 10-year limited warranty provides long-term peace of mind, and at 68 pounds for a Queen, the mattress is manageable for setup.
The most important thing to know about the Casper Element is that the cover must not be removed. It contains a fiberglass fire sock, and opening the cover can release fiberglass particles into your home. This is a significant drawback compared to fiberglass-free options like the FATHOM and Ashley Chime. The initial off-gassing odor is also more noticeable than some competitors, though it does dissipate within a few days. Despite these issues, the Casper Element remains one of the best soft mattresses for sleepers who want a balanced medium feel from a trusted brand.
Why does Casper use fiberglass in the cover?
Casper uses a fiberglass fire sock inside the cover to meet federal flammability standards without adding chemical flame retardants. Fiberglass is an effective fire barrier that does not off-gas chemicals, but it can be hazardous if the cover is opened or damaged. Casper explicitly warns against removing the cover, and you should use a mattress protector to keep the cover intact and clean.
How does the Casper Element compare to the Casper Original?
The Casper Element is the more affordable option with a simpler foam construction and a 10-inch profile. The Casper Original uses more advanced zoned support foam and has a 12-inch profile with additional comfort layers. The Element is ideal for budget-conscious buyers who still want the Casper quality and trial period, while the Original offers more premium features for a higher investment.
9. Sealy Dreamlife 14 Inch Foam Mattress
Sealy Dreamlife 14” Foam Mattress-in-a-Box, Queen, SealyComfort Gel Memory Foam, SealySupport Transition Foam, Machine Washable Cover
14 Inch Profile
Plush Feel
SealyComfort Gel Memory Foam
Machine Washable Cover
SealyCool Stretch Knit
Pros
- Firm yet soft feel with good support balance
- Excellent pressure relief on hips and back
- Machine washable cover is very convenient
- Good quality from Sealy brand
- Works well with adjustable bed frames
Cons
- Some report sinking after a few weeks
- May not be truly plush as described
- Sits on medium feel rather than soft
- Some experienced uneven settling
Sealy is a mattress industry giant, and the Dreamlife brings their decades of engineering experience to the soft mattress market. The 14-inch profile gives this mattress a substantial, premium look and feel. The 3-inch SealyComfort Gel Memory Foam layer is designed to conform to your body, and I found it does provide a comfortable level of cushioning that most users will appreciate.
The 3-inch SealySupport Transition Foam sits between the comfort layer and the base foam, adding durability and preventing the too-soft sinking sensation that some plush mattresses suffer from. The SealyCool Stretch Knit Cover enhances airflow and helps regulate temperature throughout the night. The cover is machine washable, which is a rare and valuable feature that makes maintenance significantly easier.
I particularly liked how well this mattress works with adjustable bed frames. The foam construction is flexible enough to bend with adjustable bases without stressing the materials. The CertiPUR-US certification ensures the foam meets strict standards for content, emissions, and durability, and the gel memory foam provides decent cooling for a plush mattress.
The main concern I have with the Sealy Dreamlife is the long-term durability reports. Some users mention sinking or body impressions developing after several weeks of use. This is not unusual for a softer mattress, but it is something to be aware of. The plush description may also set expectations too high, as the actual feel is more of a medium than a true soft. For sleepers who want a balanced medium-plush feel from a trusted brand with the convenience of a washable cover, the Sealy Dreamlife is worth considering among the best soft mattresses in 2026.
Can you really machine wash the Sealy Dreamlife cover?
Yes, the Sealy Dreamlife features a machine washable cover, which is one of its standout features. You can unzip and remove the cover for washing, making it easy to keep your mattress clean and fresh. Most competing mattresses require spot cleaning only, so this is a significant advantage for anyone concerned about hygiene and maintenance. Follow the care instructions on the label for best results.
Is the Sealy Dreamlife suitable for heavier individuals?
The Sealy Dreamlife works reasonably well for individuals up to about 250 pounds thanks to the thick transition foam and high-density base. However, heavier users may experience more pronounced sinking over time, as some reviews have noted. The 14-inch profile provides good depth for support, but heavier individuals who want a softer feel should consider the Classic Brands Cool Gel Chill, which has a 1,000-pound capacity.
10. Nectar Classic 12 Inch Memory Foam Mattress
Nectar Classic 12” Queen Mattress - Medium Firm - Contouring Memory Foam - Cooling Top Layer - Back Pain Relief - Mattress in a Box - 365-Night Trial & Forever Warranty
12 Inch Memory Foam
Medium Firm
365-Night Trial
Forever Warranty
Cooling Top Layer
Fiberglass Free
Pros
- Medium firm feel works for all sleep positions
- Excellent contouring and pressure relief
- Cooling top layer prevents overheating
- Great motion isolation
- 365-night trial and forever warranty
- No fiberglass and safe materials
Cons
- Some find it too firm for side sleeping
- Edge support could be better for sitting
- Cover is not removable for cleaning
- Weight capacity limited to 800 lbs
The Nectar Classic is one of the most popular mattresses in the online bedding space, and for good reason. The 365-night trial is the longest on this list, giving you a full year to decide if the mattress works for you. The Forever Warranty is equally impressive, as it does not expire as long as you own the mattress. That level of confidence from the manufacturer speaks volumes about the build quality.
The 5-layer foam construction uses a breathable cooling fabric top layer that actively draws heat away from your body. Beneath that sits contouring memory foam that adapts to your body shape, followed by dynamic support foam layers that prevent excessive sinking. The fiberglass-free construction is a major plus, and the cooling top cover does a better job of temperature regulation than most memory foam mattresses I have tested.
The medium-firm feel is where opinions diverge. Nectar positions this as a universal comfort mattress that works for all sleep positions, and that is mostly accurate for back and combination sleepers. However, strict side sleepers may find it slightly too firm, especially in the shoulder area where pressure points can develop. The contouring memory foam does help, but it does not provide the deep, plush cushioning that dedicated soft mattresses offer.
What the Nectar Classic does exceptionally well is value. The combination of a 365-night trial, forever warranty, quality cooling materials, and CertiPUR-US certified foam makes this one of the most compelling packages in the mattress industry. The motion isolation is top-tier, making it excellent for couples. If you want a mattress from a brand that stands behind its product with industry-leading trial and warranty terms, the Nectar Classic is hard to beat among the best soft mattresses we reviewed.
How does the 365-night trial actually work?
Nectar requires a 30-day break-in period before you can initiate a return, which gives your body time to adjust to the new mattress. After 30 days, you have until day 365 to request a return if you are not satisfied. Returns are free, and Nectar arranges pickup and removal of the mattress. The forever warranty covers manufacturing defects for as long as you own the mattress, which is genuinely unique in the industry.
Is the Nectar Classic better than the Nectar Premier?
The Nectar Classic is the more affordable option with a 12-inch profile and medium-firm feel. The Nectar Premier adds a thicker comfort layer with more premium cooling materials and a softer overall feel. If you specifically want a softer mattress, the Premier is the better choice. The Classic is ideal if you want a balanced medium feel with the best trial and warranty terms available.
Buying Guide: How to Choose the Best Soft Mattress
Choosing the right soft mattress involves understanding firmness scales, material types, and how different features affect your sleep quality. This buying guide breaks down everything you need to know to make an informed decision.
What Makes a Mattress Soft: The Firmness Scale Explained
Mattress firmness is rated on a scale of 1 to 10, where 1 is the softest possible feel and 10 is the firmest. A soft mattress typically rates between 3 and 5 on this scale. Medium-soft mattresses land around 4 to 5, while ultra-plush options can go as low as 3. The firmness rating is determined by how deeply your body sinks into the comfort layers when lying on the mattress.
It is important to understand that firmness and support are not the same thing. A soft mattress can still be highly supportive if it has a well-engineered support core beneath the plush comfort layers. The best soft mattresses use zoned support systems, high-density base foams, or pocketed coil systems to maintain spinal alignment while providing that cushioned, pressure-relieving top feel.
Who Should Buy a Soft Mattress
Soft mattresses are ideal for side sleepers who need pressure relief at the shoulders and hips. When you sleep on your side, your body weight concentrates at these two points, and a firm mattress can create painful pressure buildup. A soft feel mattress allows these areas to sink in comfortably, distributing weight more evenly and reducing joint pain.
Lightweight sleepers under 130 pounds also benefit from softer mattresses because they do not exert enough weight to compress firmer comfort layers. Without sufficient sink, lighter sleepers may find a medium-firm mattress feels like lying on a board. Couples who want excellent motion isolation often prefer softer memory foam mattresses, as the plush materials absorb movement better than firmer options.
Who Should Avoid a Soft Mattress
Stomach sleepers should generally avoid soft mattresses because the plush comfort layers allow the midsection to sink too deeply, which throws the spine out of alignment. This can lead to lower back pain and discomfort over time. Stomach sleepers typically need a medium-firm to firm mattress that keeps the hips from sinking.
Heavier individuals over 230 pounds may also find that soft mattresses do not provide adequate support. The softer comfort layers can compress fully under higher body weight, causing you to bottom out on the support core. If you are a heavier sleeper who still wants some cushioning, look for a medium-firm mattress with a thin comfort layer rather than a truly soft design. People with certain back conditions like scoliosis should also consult with a medical professional before choosing a soft mattress, as some conditions require firmer support.
Key Features to Consider
Pressure Relief: The primary benefit of a soft mattress is pressure point relief. Look for mattresses with thick comfort layers of memory foam or gel foam, as these materials contour around your body and distribute weight evenly. The best soft mattresses for pressure relief use at least 3 inches of memory foam or gel foam in the comfort layer.
Motion Isolation: If you share your bed, motion isolation is critical. Memory foam and gel foam excel at absorbing movement, so all-foam soft mattresses generally outperform hybrids in this category. Look for mattresses with at least 2 inches of memory foam to minimize motion transfer between sleep partners.
Cooling Technology: Soft mattresses can sleep warm because the body sinks into the foam, which traps heat. Look for mattresses with gel-infused foam, phase change materials, open-cell foam structures, or breathable covers. The Classic Brands Cool Gel Chill and Sweetnight CoolNest are standout options for hot sleepers who want a softer feel.
Edge Support: Soft mattresses often have weaker edge support because the plush comfort layers extend to the edges. If edge support matters to you for sitting on the bed or maximizing the usable sleep surface, look for mattresses with reinforced edge support or denser foam perimeters. The Serta Sleeptrue has notably better edge support than most all-foam options.
Materials Comparison
Memory foam is the most common material in soft mattresses because it provides the deepest contouring and pressure relief. Gel-infused memory foam adds cooling properties by drawing heat away from the body. Phase change material foam goes a step further by actively regulating temperature through phase transitions. High-density support foam in the base layer ensures long-term durability and prevents sagging.
CertiPUR-US certification is a must-have for any foam mattress. This certification guarantees the foam is made without ozone depleters, heavy metals, and dangerous flame retardants. It also sets limits on VOC emissions, which reduces off-gassing odor. Every mattress on our list has CertiPUR-US certified foam, and several also have Oeko-Tex certified fabrics for additional safety assurance.
Sleep Trials and Warranties
A generous sleep trial is essential when buying a soft mattress because firmness is subjective and personal. The Nectar Classic leads the pack with a 365-night trial, while most competitors offer 100 nights. Look for trials with free returns and no restocking fees. The trial period should give you enough time to fully break in the mattress and determine if the softness level works for your body type and sleep position.
Warranties range from 10 years to lifetime coverage. The Nectar’s Forever Warranty is the most generous, covering manufacturing defects for as long as you own the mattress. The Ashley Chime offers a 10-year non-prorated warranty, which maintains full replacement value over the entire term. Always read the warranty terms carefully, as some manufacturers require you to use a specific type of foundation or base to keep the warranty valid.
FAQs
What kind of mattress is the softest?
Memory foam mattresses with thick comfort layers of 4 inches or more are generally the softest available. Mattresses with Euro pillow tops, plush gel memory foam, and phase change material foam tend to provide the deepest cushioning. Among our tested products, the Amazon Basics Plush and Ashley Chime Extra Plush offer the softest feel profiles.
Which mattress brand is the softest?
For genuinely soft mattresses, brands like Nectar, Sealy, and Serta offer dedicated plush models. Among the mattresses we tested, the Amazon Basics Soft Plush Feel, Ashley Chime Extra Plush, and Sealy Dreamlife Plush provide the most pronounced soft feel. Tempur-Pedic is also known for accurate softness labeling, though their models are not included in this budget-focused roundup.
Are soft mattresses good for side sleepers?
Yes, soft mattresses are excellent for side sleepers. When you sleep on your side, your shoulders and hips bear most of your body weight. A soft mattress with at least 3 inches of memory foam or gel foam allows these pressure points to sink in comfortably, reducing joint pain and improving spinal alignment. The FATHOM Medium and Sweetnight CoolNest with its 5-zone support are particularly good for side sleepers.
Can a soft mattress cause back pain?
A soft mattress can contribute to back pain if it lacks proper support beneath the comfort layers. If your hips sink too deeply, your spine can curve unnaturally, leading to lower back pain. The key is choosing a soft mattress with a firm support core or zoned support system. If you have existing back conditions like scoliosis, consult a medical professional before choosing a soft mattress, as a medium-firm option may be more appropriate.
