If you sleep on your side or you’re petite, you’re going to need a soft mattress that cradles you at night. But how can you tell if a mattress is soft or firm just by looking at a picture of it online? Manufacturers typically use a firmness scale of 1 to 10 to give you a general sense of a mattress’ feel, with 1 being the softest and 10 being the firmest mattress.

After years of testing mattresses, we’ve scoured the corners of the sleep realm for the top soft mattress options. We know what it takes for a mattress to be really soft and what materials you should look for if you want to sleep on a cloud. Here are our top picks for the best soft mattresses you can buy. 

What’s the best soft mattress?

The GravityLux is a luxury mattress from WinkBeds. It has three firmness options, allowing you to customize the mattress. The soft or medium option is good for people who want a bed with pressure relief. It’s the kind of mattress that could work for anyone. That’s why we think it’s the best soft mattress you can buy. 

This soft mattress also has a “progressive support” design for all the layers, which is firm and soft where your body needs it most. The layers are thick, proprietary foam with cooling technology and extra durability.

The Winkbeds GravityLux mattress is targeted toward a range of sleepers who want a luxury mattress at a good price. With Winkbeds, you choose your own firmness level when you choose your mattress size so if you prefer, you can be sure to get the softest most comfortable mattress variety available (they offer soft, medium and firm).

Crafted with multiple layers of thick, proprietary foam, this mattress also offers seven layers of support to combine for the perfect soft mattress. From top to bottom, this mattress consists of a tufted cooling-gel-infused cover, then a layer of the company’s patented AirCell memory foam, which relieves pressure, dissipates heat and minimizes motion transfer. Another layer of memory foam comes next, called Progression foam, which varies in its supportiveness and softness depending upon what each region of your body needs. Finally, the Atlas Core foam is at the base of the mattress, adding to its durability.

Price: $$

Pros:

• Multiple firmness levels
• Cooling-gel-infused cover

The Puffy Lux Hybrid offers just enough decadent softness with a spritz of firmness and pressure relief sprinkled in. This bed provides a comfy, airy memory foam feel that I find extremely cozy. Puffy describes the Lux Hybrid as their most popular mattress, at 12 inches thick with six full foam layers and pocketed coils.

First, there’s 1.5 inches of gel-infused cooling foam, followed by another 1.5 inches of plush pressure-relieving foam and 2 inches of moisture-resistant foam. At the bottom of this Puffy mattress, there’s a final 7 inches of high-density foam with a coil base to keep things sufficiently supportive and provide edge support.

All the Puffy Lux mattress foams are CertiPUR certified, meaning the mattress brand creates this mattress type without ozone depleters, formaldehyde, toxic flame retardants or other toxic ingredients. Read more in our full Puffy Lux mattress review. 

Pros:

• Ultra-soft, marshmallowy feel 
• Hybrid mattress is good for any body type
• Machine washable cover

Made in the USA, the Helix Sunset Mattress Luxe has a plush feel with a 1-2 rating on the firmness scale, the softest bed possible.

The mattress then has a layer of the company’s super soft Memory Plus foam for pressure relief, followed by Helix Dynamic Foam for contouring.

The Layla mattress is a flippable mattress with two firmnesses in one. One side is around a medium to medium firm, while the other is a medium-soft. Soft bed lovers are going to love the plush side of the Layla mattress. It’s a light and airy memory foam with copper-infused material to help draw heat away from your body. 

The original Layla mattress is made with just foam, so it’s going to be better for people who weigh under 230 pounds. If you’re looking for more support, however, the Layla Hybrid mattress is also an option. It has the same flippable design, but it’s made with strong pocketed coils to add more support and durability. 

Price: $$

Pros:

• Two firmness levels in flippable design 
• Airy memory foam feel 
• Good temperature regulation 

Cons:

• Not people who want a bouncy mattress

Other mattresses we’ve tested

Aside from the soft mattresses listed above, there are over 100 other beds our CNET Sleep editors have tested. The ones chosen here for our best soft mattress list are among the best of the best, but there are several other beds that deserve an honorable mention. 

Brooklyn Bedding Signature: Brooklyn Bedding is one of the only online mattress brands that make and manufacture their own beds, so the prices are extremely fair and reasonable. I’d argue the Signature mattress is one of the best values. It comes in three firmness levels, but the soft model is rated around a 3 or medium-soft. It also has a bouncy, neutral-foam feel that I predict most people will find comfortable. 

WinkBed mattress: The WinkBed is a luxury-hotel-worthy bed with a strong hybrid construction. It’s made with memory foam, but it has more of a neutral, innerspring mattress feel. Its pillow top gives it a plush feel, while the innersprings make it feel supportive and springy. It also has three different firmness levels. 

Leesa Legend mattress: The Leesa Legend is quality-built and perfectly plush bed. It has two different layers of springs, a design only a handful of beds use. This makes it a bit more bouncy than a memory foam mattress, which takes a few moments to react to pressure. It’s rated around a five out of 10 on the scale or a medium, but its light and airy foam feel makes it feel soft and inviting. How we tested the best soft mattresses

How we tested the best soft mattresses

Over our years of testing mattresses, we’ve established tests we use to assess mattresses on key factors. 

Firmness and feel

You can think of firmness as how hard or soft a mattress is when you are lying on it. We’ve tested hundreds of mattresses and have an extensive catalog to compare against each new bed we test. 

When assessing for feel, we get handsy with the bed. As we press on the bed, we watch what the material does. Does it take a second to bounce back like traditional memory foam, or is it quick and bouncy like latex foam?

Durability

Mattresses don’t last forever, and you want to buy one that lasts. Based on its construction, we hypothesize how well a mattress will stand up to nightly use. Beds that have steel coils as a base will generally last longer than all-foam mattresses.

Motion isolation

Motion isolation is how well a mattress dampens movement across the surface. It’s a big deal for people who sleep with a partner or pet who moves around at night. We jump and bounce around on the mattress for motion isolation and see how much movement is detected. We also place a glass of water on the edge of the bed and roll around and bounce near it. If it doesn’t topple over, a mattress has good motion isolation. 

Edge support

A mattress’s edge support is how strong the bed’s perimeter is. We lay and sit on the edge of the mattress and assess how sturdy it feels. If we feel like we will fall off, then a bed doesn’t have good edge support. 

Temperature 

Hot sleepers need to look for mattresses with cooling technology. Many mattresses claim to have it, but we know the difference between marketing and cooling construction that will actually keep you cool. 

Our CNET Sleep editors picked the beds and other products we write about based on editorial merit. When you buy through our links, we may get a commission. Find out more on how we test mattresses. 

What to consider when shopping for a soft mattress

Buying a soft mattress is a big decision. There are a lot of options out there, and not every bed out there will be the best choice for you. There are four key factors to remember when browsing: sleeping position, body type, health conditions and your budget. 

Sleeping position 

How you sleep matters when choosing the firmness of your mattress. 

• Side sleepers need soft to medium mattresses with plenty of pressure relief to ensure pressure points don’t develop on the shoulders, hips or knees. Think soft memory foam or plush pillow tops that conform to the curves of your body. 
• Back and stomach sleepers need a medium to firm mattress to keep the spine aligned throughout the night. If a mattress is too soft, you’ll wake up with back pain. 
• Combination sleepers have the most flexibility in firmness. However, you should decide based on the position you spend the most time in. 

Body type

Your weight will determine how much pressure you put on a mattress, which influences how firm you experience it. Plus-size body types will experience mattresses softer than a petite body type who puts less pressure on the bed. 

• People over 230 pounds require a mattress with lots of support from coils, like hybrid mattresses. 
• People under 230 pounds can choose between foam and hybrid mattresses, though the less you weigh, the more firm it will seem. 

Health conditions 

Your needs are another crucial factor to remember when shopping for a bed. You should choose a firmer mattress if you’re someone with back pain. If you suffer from joint pain, choose a softer bed that will cradle you at night. 

If you sleep hot, look for a mattress with cooling technology in the foam or cover. Or you can opt for a naturally breathable bed with latex foam. 

Budget 

Mattresses aren’t a small purchase; even the most affordable bed will cost a few hundred dollars. The average cost of an online mattress is $850 to $1,200. Establishing your budget will help you filter out mattresses and narrow down your pool of options. There are mattresses for every budget, from under $300 to luxury hotel mattresses that cost over $2,000. 

What are the benefits of a soft mattress?

Besides being ultra comfortable to snuggle up in, the best soft mattresses are ideal for side sleepers and petite individuals who seek more pressure relief.

• Soft mattresses allow the hips and shoulders to press into the bed’s comfort layers, providing pressure relief to those joints. 
• For side sleepers, a soft mattress will help promote proper spinal alignment because they are more contouring around the shoulders and hips and have more give. 
• The lighter you are, the firmer a bed feels. Petite sleepers under around 150 pounds may want a softer mattress because the average “medium” firmness mattress will feel more like a medium-firm.
