Best Soft Mattress

Shopping for the best soft mattress balances a fine line between support and firmness. While you may want it to feel soft to the touch, you also want it to provide the correct type of support for your sleeping style. Different factors like sleeping position, body weight, and environmental factors can all play a role in selecting your perfect mattress. And also, keep in mind what is best for one body might not be best for another.

Throughout this guide, we’re going to walk through many of the most important considerations to look at when selecting the best soft mattress. We’ll review what makes a soft mattress great and who benefits the most from soft mattresses.

Best Soft Mattresses of 2021

What’s the Best Soft Mattress?

So what’s the best plush mattress on the market? The best soft mattress will have optimal mattress support without resulting in unnecessary firmness. It will provide body-contouring, pressure relief, and deep compression support. Side sleepers may gravitate towards soft mattresses more than any other type of sleeper.

Lastly, the best soft mattress will not be prone to “sleeping hot”. The right use of materials will allow air to flow throughout the night and prevent heat retention around the sleeper.

Best Mattress for the Money

The Midnight version of the Helix mattress

Helix Sunset Mattress

One mattress that delivers on soft and value is the Helix mattress. Helix actually builds a mattress custom based on your preferences, so the mattress can meet a variety of needs – but one of those needs is definitely soft!

The Helix construction always varies, but a soft hybrid construction will suit a lot of people looking for a comfortable soft mattress. Learn more in my full Helix mattress review.

Best Soft Memory Foam Mattress

Pressing into the Layla mattress

Layla Mattress

I’m going to have to be a little bit more specific with the Layla as it is a flippable mattress, so it gives you a choice of softer or firmer support depending on which side of the mattress you have on top. Both sides of Layla use copper infused memory foam for pressure relief but since this is the video for Best Soft Mattress I’m going to recommend putting the Soft side up.

I mentioned the memory foam in the Layla is infused with copper and that was done for a reason as it helps to draw heat away from the sleeper. This is important because while memory foam has great advantages for comfort, one of its drawbacks is that it traps body heat. Layla has made a pretty breathable memory foam that provides relief, while still allowing the sleeper to stay cool.

Price normally ranges from $499 – $999 but you can save $110 but using the code SLEEPOPOLIS at checkout.

The Layla has a few other great construction features including copper infused memory foam, which helps you sleep cool as well. Learn more in my full Layla mattress review.

Best Innerspring Mattress

The Saatva mattress in the Sleepopolis studio.


While you may not think that an innerspring mattress could be soft, there are a few springy options on the market that are actually quite gentle. For an introduction to one of these dreamy beauties, let’s take a look at the Saatva mattress. 

Built with a coil-on-coil construction, this innerspring mattress is bouncy and supportive, working as it does to position the sleeper on top of the structure. This can be great for folks who struggle with aches and pains, as it means the spine will be lifted into a healthy alignment. But one of the coolest things about the Saatva mattress is that it’s actually available in three different firmnesses: Plush Soft, Luxury Firm, and Firm. If you’re after a softer vibe, I’d recommend checking out the Plush Soft Saatva, which features gentle foams and extra padding in the pillow top layer.

Best Soft Mattress for Shoulder Pain

The memory foam of the Nectar is great for side sleepers.


Soft mattresses can be great for shoulder pain. Typically built with gentle materials like memory foam, these beds cushion the shoulders and alleviate tension all night long. If you think a soft mattress might be the ticket for you, I recommend checking out the Nectar mattress. 

This bed features a whopping five inches of plush memory foam in its top layers. This translates to ample sinkage, pressure relief, and body-contouring, all attributes that do wonders for those who struggle with shoulder pain. The secret is that the longer you rest on top of a memory foam mattress, the more its layers contour to your shoulders, hips, and lower back. This helps to provide a little cushiony support to these sensitive spots and ensure endless nights of pain-free sleep.

Best Soft Mattress for Side Sleepers

The GhostBed 3D Matrix.

GhostBed 3D Matrix

In general I like soft mattresses for side sleepers because they provide better pressure relief, something that benefits side sleepers especially because they put so much weight over their shoulders. The GhostBed 3D Matrix has a softer feel thanks to its gel memory foam comfort layer, which allows for a contouring feel as you sink into bed. A lot of memory foam mattresses can cause the sleeper to feel stuck in bed, but because this is a hybrid mattress, the pocketed coils provide some really nice bounce so you can move around easily.

Along with side sleepers I also think couples will like the GhostBed 3D Matrix because it does a good job isolating motion transfer and is nice and cooling, which are two key factors for many couples. This mattress actually uses a special gel polymer layer to dissipate body heat, so it sleeps cooler than most other memory foam mattresses on the market.

Best Soft Mattress for Combination Sleepers

The Amerisleep AS5 is super soft.

Amerisleep AS5 Mattress

The Amerisleep line ranges in support from the extra firm (AS1) to the extremely plush (AS5). Since this list is looking at the best soft mattresses available, I would lean towards the AS5 model. For combination sleepers looking for a soft feel I would go with Amerisleep AS5.

The AS5 uses a combination of proprietary Bio-Pur foam and ActiveFlex foam in its comfort layers, which allow the sleeper to sink deep into bed for pressure relief, but I still found that it responded to pressure quick enough to allow me to change positions. Along with that the AS5 has enough support for back/side combo sleepers to have good spinal alignment in both positions

Best Soft Mattress for Back Sleepers

The Leesa Hybrid has a nice mix of support and pressure relief

Leesa Hybrid Mattress

The Leesa Hybrid mattress is a bed that I really like for back sleepers looking for a soft feel. It’s soft enough to offer plenty of pressure relief, but its pocketed coil layer offers enough support to help keep these folks comfortable.

This mattress is bouncy and responsive, which is great for combination sleepers because it is easy to move around and change positions on. Most back and side combo sleepers will find this mattress just supportive enough to keep their spine neutrally aligned, but soft enough that it will fill in the lumbar region (lower back) and cushion other sensitive parts of the body.

Best Soft Mattress for Back Pain

The WinkBed Mattress

WinkBeds Mattress

So far I’ve talked about an all foam mattress and one that uses polymer for comfort, but what if you’re interested in a more traditional pillow top build? You’re in luck because the WinkBed is a hybrid mattress that provide the feel of an old school bed.

WinkBed makes this mattress in three firmnesses (as well as a plus version for heavier folks in need of more support) and I find their ratings to be pretty true to their support level, so if you’re looking for a soft mattress go with the soft WinkBed. Even with the soft foams and microcoils on top, the WinkBed is well supported with zoned coil support below.

Another benefit of the WinkBed is that it sleeps cool thanks to its breathability, tencel cover and gel infused foams. So if you’re looking for a traditional innerspring feel that sleeps a bit cooler then I can definitely recommend the WinkBed.

Price on the WinkBed ranges from $1049 – $1849 but you can save $200 by using the code SLEEPOPOLIS200

Best Medium Soft Mattress

Back sleeping on the Casper Wave Hybrid

Casper Wave Hybrid

If you’re looking for a soft feel without sacrificing too much support then something more in the medium support range might be to your liking. The Casper Wave Hybrid uses proprietary Airscape foam which offers incredible pressure relief and has cooling properties. But this mattress isn’t just cloud like comfort, there’s also some good support below for good spinal alignment.

Unsurprisingly I think side sleepers are going to love the soft feel of the Casper Wave Hybrid, but I also think back sleepers that like a memory foam feel will appreciate it as well. If you want to get into bed and sink into the layers, without sacrificing some medium support, take a look at the Casper Wave Hybrid.

Mattress Support vs. Firmness

Above all else in a mattress, support is absolutely KEY. Now, that may trip up some sleepers… ““wait… I thought this guide was about soft mattresses, I don’t want too much support”. Firmness equating support is a bit of a misnomer. Mattress support and mattress firmness are two stand-alone qualities in any mattress. While they do work in tandem, they are not one and the same. For instance, a mattress could have a soft feel with great support or a firm feel with lousy support.

Good mattress support simply means that it keeps your spine in proper alignment without creating pressure points. Irritating pressure points can lead to back pain and restless night.

Mattress firmness, on the other hand, is defined as how hard or soft a mattress feels. Different manufacturers use different materials to convey varying levels of firmness.

FAQWhat mattress firmness do I need?

It’s most important to remember that support and firmness are different. Soft mattresses can still provide great support. However, softer mattresses are held to a higher standard in terms of material quality in order to provide that level of support. With softer materials also come new potential problems, including heat retention, feeling stuck, or spinal alignment issues. Good design and material selection helps to minimize these issues, while still creating a soft cloud-like feeling.

Who is a soft mattress right for?

Softer mattresses can be appropriate for a variety of sleeper types and positions. In general, softer mattresses are ideally suited for side sleepers. The softer layers allow for a better contouring hug and support along the curves of the body. Some back and stomach sleepers may also enjoy the softer feel, but it really comes down a personal preference for these sleepers.

Stomach sleepers especially should be wary of going too soft, as the deeper hug can create a lack of support along the mid section, creating pressure points and pain in the lower back.

Sleepers who weight less (150 pounds or less) may also find that soft suits their needs better. Lighter sleepers may float on top of medium or firmer mattresses due to the materials that require higher pressure levels before creating sinkage. The softer materials allow sinkage at lower weights, creating better pressure relief for these sleepers.

Do soft mattresses “sleep hot”?

In the mattress world, there is a condition that some mattresses suffer from called “sleeping hot”. This can occur for a variety of reasons, but the most common are 1) the materials (usually memory foam) are absorbing and retaining heat and/or 2) the level of hug in the mattress is such that an excess of material is wrapping around the sleeper. In general, soft mattresses are more susceptible to sleeping hot than medium or firm mattresses.

FAQ:  What’s the best cooling sheets?

For this reason, it’s critically important to consider the design, construction, and materials of the mattress. Soft mattresses that use large amounts of memory foam, especially in the top layers, may be more likely to sleep warm because they retain heat. Ventilated memory foam or memory foams infused with gel, copper, or other cooling materials can help to mitigate some of the heat risk.

Example of cooling design and material factors (Amerisleep Colonial pictured)
Example of cooling design and material factors (Amerisleep Colonial pictured)

If you are concerned about sleeping warm you will want to look for mattresses that:

  1. Use a thin cover – this will minimize the quantity of material wrapping around you
  2. Use a design that places memory foam below the top layers – top layers of latex, polymer, gel, pillow tops, or other more breathable materials will help to reduce the risk of heat retention
  3. Use advanced memory foam – not all memory foam is created equal, some memory foams are more advanced in terms of their ability to breathe and not retain heat
  4. Use coils – coil mattresses that use pillow tops or true hybrid mattresses generally breathe better and remain cooler than 100% foam mattresses

Will a soft mattress help with my back pain?

For many sleepers, back pain is a frustrating part of their nightly routine. Back pain can occur for any type of sleeper, regardless of what position you sleep in. Also, it can be caused by a variety of factors, but one of the most common is inadequate mattress support. In general, most who struggle with back pain will require a medium, slightly firm, or firm mattress. A soft mattress, even one with good support, can create additional problems and pain for the back.

FAQ:  What’s the best mattress for back pain?

For those who suffer with back pain, but are certain they still want / need a softer feel, selecting a mattress with a modern thin cover design can help. Traditional quilted covers, padded, or pillow top covers that are excessively soft are most liable to exacerbate back pain. However, thin covers where the softness of the mattress is derived from supportive foam, coil, or hybrid layers generally provide a stronger and more supportive base.
