The Layla Mattress is one of the best soft mattresses on the market. What’s unique about it is that it’s also one of the best medium firm mattresses. How does that work? Well, Layla can be flipped over, with a soft side and a firm side. Depending on your preferences, you can sleep on either side. Regardless of which side you use, Layla is impressively supportive and comfortable – providing great response in deep compression areas where support is most needed.

The Layla mattress is made up of 4 layers: copper infused memory foam, convoluted air flow foam, supportive base foam, and copper infused memory foam. If you’re wondering if you read that right, you did – there is copper in this mattress. Copper is an excellent conductor, which basically means that it can suck up the heat that your body creates through the night, and distribute it throughout the mattress. This can help keep you cool at night, and is particularly awesome in warm climates. Copper also has antimicrobial properties, which helps keep your mattress clean.

Each Layla mattress comes with a 120-night risk-free trial – which means if you are not satisfied, you can return your mattress at any time during the first 4 months. Overall, Layla offers fantastic value – especially given the affordable price, which ranges from $599 to $1099 depending on the mattress size. Right now, you can save an additional $100 with coupon code SLEEPZOO

See Deal

The Helix is a fully customizable mattress. When you go to purchase a Helix, you’ll take a quick survey that will gather information on your sleep preferences, physical size, preferred sleep position, etc. This data is then used to recommend a specific custom mattress composition tailored to your every needs!

To make things even more customizable, you can actually design each side of the mattress separately. So, if you prefer a softer bed but your partner likes a firmer feel, you can both get what you want! This makes Helix one of the best beds for couples, and by far the most customization-friendly bed we’ve seen.

When it comes to their softest mattress it would be the Helix Moonlight Series which has a Luxe upgrade option for added features.

Helix offers a generous trial period, so you can try it out risk-free for 100 nights. If you’d like to do some more reading, check out our full Helix review.


Hybrid: Eight Sleep Mars+

Eight Sleep Mars+

Key Features: Smart technology tracks and analyzes your sleep; hybrid design offers comfort of memory foam with support of innerspring

Price Range (Twin-Cal. King): $1299-$1599

Risk-Free Trial: 100 nights

Save $50 with Code SLEEPZOO

The Eight Sleep Mars+ is a fantastic mattress from an up-and-coming manufacturer. It’s the softest model offered by Eight, however it tends to fall in the middle of the firmness scale in our tests. Therefore, it’s best for those who like a soft-ish mattress, but also want the additional support of a slightly firmer bed.

The Mars+ is a hybrid mattress, which means it has both coils and foam. This provides the best of both worlds – excellent support from the coils, and premium comfort/softness from the foam. The foam is made of reactive polyester, which is designed to have the bounce of latex with the soft feel of foam – making it a good mattress for sex – while the mattress also offers impressive motion isolation, making it a good bed for couples in general.

While the hybrid design, premium poly foam and impressive support make the Mars+ a great all-around mattress, the real value of this bed in our opinion is the smart features. The Mars+ comes with a smart mattress cover that tracks 15 different factors relating to your sleep quality and health. It tracks heart rate, respiratory rate, deep sleep, sleep cycles, sleep duration, and more. It even features a smart alarm that can detect when your body enters a lighter sleep cycle, making it easier to wake feeling rested. The Mars+ can integrate with your smart home system, can be controlled by your smartphone, and can even regulate the temperature of your bed!

All in, the Eight Sleep Mars+ is an ultra-premium smart mattress at an affordable price. It’s priced from $1300, with a 100-day risk-free trial. Eight also offers an industry-leading 10-year warranty.

Our Eight Sleep Mars+ review has all the details you’re looking for about this technology-driven mattress. And for those looking for a great deal, you can grab an Eight Sleep coupon code and save $50 with code SLEEPZOO at checkout.

Who Benefits from a Soft Mattress?

As with every type of mattress, a softer bed will benefit some people more than others. Things like whether you’re a back sleeper or a side sleeper, your body weight, and any health concerns will determine whether you should have a soft mattress or a firmer one. So, who are the softest mattresses designed for?

Side sleepers – Soft beds will hug your curves, while still offering support – so they are a popular choice among side sleepers. While soft beds can still be used in other sleep positions, if you sleep on your stomach, having a soft mattress can cause you to feel less supported in your mid-section. This can end up causing lower back pain, so stomach sleepers should be cautious when opting for a soft bed. Side sleeping is the most common position for Americans, and many experts believe that side sleeping is the healthiest sleep position:

“The best sleep position is a side posture fetal pose, with legs curled and pillow between your knees, which keeps the pelvis level and reduces the chances of lower back irritation, stiffness or pain.” – Dr. Lou Bisogni, New York chiropractor.

Petite Sleepers – The softest mattress is going to be better suited to sleepers that are around or under 150 pounds. While firmer mattresses require some weight to create sinkage, a soft bed will create sinkage faster. For lighter sleepers, this creates a higher level of comfort and pressure relief.

Sleepers without Back ProblemsBack pain is a huge problem for many people. If you have back pain, you’re typically going to do better with a medium or firm mattress.


Who Shouldn’t Sleep on a Soft Mattress?

Soft mattresses aren’t right for everyone. Some people will do better on a medium or even firm mattress. The most common groups that should avoid soft mattresses are:

Sleepers with Back Pain – if you regularly experience back pain upon waking up, it could be due to the position you are sleeping in. Or, it could be because your mattress is too soft. Harvard research suggests that those with back pain should avoid very soft – and very hard – mattresses, and opt for a medium firm or firm mattress.

Overweight Sleepers – if you are overweight, or simply just weigh a lot due to your large frame, you should also likely avoid soft mattresses. These ultra-plush mattress options tend to provide too much give/sag for heavier sleepers, which can lead to back problems.

Back Sleepers – typically, those who prefer to sleep on their backs do better on a medium to firm mattress. Personal preference certainly comes into play here, but it’s fairly rare for a back sleeper to find a very soft mattress to be comfortable.


Our Credentials

You’ve seen our recommendations for the best soft mattress – but why should you trust us? How are we any better than the average mattress salesman, or your buddy Mike who just bought a new bed?

Experience – our team is lead by Chris Brantner, Certified Sleep Science Coach whose expert opinions have been featured in the likes of NBC News, Huffington Post, Bustle, Brit + Co, Fatherly, and more.

Testing – our team has spent countless hours testing various mattress models from many of the top online mattress brands. We worked hard to individually analyze the unique characteristics of each model, breaking down pros and cons and identifying which models made the most sense for our readers.

Research – to verify and expand on our own findings, we conducted extensive online research on each model we reviewed. We looked not only at manufacturer specs to identify materials, manufacturing processes and durability, but also at hundreds of third-party customer reviews. By analyzing research from Consumer Reports, combined with the opinions of hundreds of verified customers on Amazon and other online retailers, we were able to round out our own findings and ensure that no detail was missed.

Interest – unlike many websites who focus solely on mattress reviews, we have a genuine interest (okay, obsession) with sleep. We regularly research and report on sleep science, sleep tips and sleep news. We want our readers to get better, more restful sleep, and we realize that that pursuit involves more than just finding the right mattress.


How We Chose the Best Soft Mattress

With over 35 MILLION mattresses shipped each year and literally thousands of different models on the market, one might wonder how we went about choosing the best soft beds for our readers. We utilized a combination of factors, including:

Softness – shocking, we know. The first aspect we looked at was the actual softness of the bed. We looked at how the manufacturer labeled the mattress – soft, ultra soft, plush, ultra plush, etc. and then compared that to our own findings, and the reports of consumers in soft mattress reviews. In some cases, the manufacturer’s stated category was not accurate enough in our opinion, so we went the extra mile to ensure it was the right softness level for this guide.

Materials – we looked at the materials and manufacturing processes that each mattress company used to produce their beds. Soft mattresses sometimes have sagging issues later in their life, so it’s essential to select a mattress that is well made. Cheap soft mattresses might be tempting – and they will even be comfortable initially – but you will find their lifespan to be quite short. We chose only models made using the best materials, to ensure longevity.

Motion Isolation – since many of our readers share their beds with a partner and want a good mattress for couples, we picked mattresses that have good “motion isolation”, or a lack of “motion transfer”. This essentially refers to the level of movement in the rest of the bed when you get up. When you get out of a bed with good motion isolation, your partner likely won’t even notice, even if they are a light sleeper.

Value – we like finding great deals for our readers. While some people might buy mattresses that cost more than a new car, we recognize that most of our readers want to find a great mattress at a great price. Therefore, price played a major role in our decision making process – but it certainly wasn’t the main factor we looked at. Regardless, all our picks represent a fantastic value at their price point.

Perks – even the best soft mattress is nothing without a solid manufacturer warranty, customer support, etc. So, beyond looking at the mattress itself, we put a magnifying glass on the manufacturer and their policies. We looked for manufacturers and retailers that offered good warranties, extended free trial periods, and helpful customer support.

Soft Mattress FAQ

Still have questions about choosing the best soft mattress? Here are some answers to frequently asked questions our readers send us:

What is the softest mattress on the market?

In general, plush mattresses are the softest mattress you can get without adding a separate pillowtop mattress pad. One of the softest mattresses we’ve tested to date is the Nolah foam mattress.

Is it better to have a soft or firm mattress?

There’s not a simple, one-size-fits-all answer to this question. A mattress that’s too firm will put too much stress on your pressure points, while one that’s too soft could lack proper pressure point support. Really, it depends on your size, weight, any ailments you might have (e.g. back pain), and your preferred sleeping position. In general, a soft mattress is best for side sleepers and smaller individuals.

Can a bed that is too soft hurt your back?

If a mattress is overly soft and you’re a larger person, it could cause back pain as your spine won’t get the support it needs for proper alignment. But a typical soft mattress is fine for the average person, especially those who are side sleepers.
