Best soft mattress for side sleepers

Helix Sunset Luxe

Our take -  The WinkBeds GravityLux mattress is targeted toward sleepers who want a luxury mattress at a good price. With WinkBeds, you choose your own firmness level when you select your mattress size. You can get the softest, most pressure-relieving mattress variety available with their soft model (they offer soft, medium and firm).

Our take -  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. Standing 12 inches tall and comprised of six foam layers and pocketed coils, Puffy describes the Lux Hybrid as their most popular mattress.

Our take -  The Brooklyn Bedding Aurora Luxe hybrid mattress is a pillowy-soft bed with innovative cooling features that bring the body's skin temperature down to the ideal 88 degrees recommended for a cool, peaceful night's sleep. 

Our take - Most people assume that because someone has back pain, they need a super firm mattress to alleviate pain. Some people prefer soft mattresses, often because they sleep on their side. The Saatva Rx mattress is on the softer side of medium or a 4 or 5 out of 10 on our firmness scale. 

Our take -  The Amerisleep AS5 Hybrid mattress is the perfect soft mattress for heavier side sleepers. It's about as pressure-relieving as a mattress can get while still being supportive. The 14-inch thick Amerisleep AS5 Hybrid memory foam mattress features an airy, breathable soft feel cover. This is followed by a plant-based foam called Bio-Pur for contouring and pressure relief; this foam also has an open-cell design to promote airflow. Bio-Pur foam is mildew, mold and dust mite resistant and CertiPUR-US certified. It also tests low in emissions. 

Our take -  The Layla mattress is a flippable mattress with two firmness levels in one. One side is around a medium to medium-firm, while the other is a medium-soft. Soft bed lovers will 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. 

In addition to the soft mattresses listed above, our CNET Sleep editors have tested over 100 other beds. The ones chosen for our best soft mattress list are among the best, but several other beds deserve an honorable mention. 

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

WinkBed mattress: The WinkBed is a luxury-hotel-worthy bed with a solid hybrid construction. It's made with memory foam but has a more neutral, innerspring mattress feel. Its pillow top gives it a plush feel, while the inner springs 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 5 out of 10 on the scale or a medium, but its light and airy foam feel makes it feel soft and inviting.

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 lie 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.

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: 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. Combination sleepers have the most flexibility in firmness. 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, although 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.

Soft beds are best for side sleepers. If you sleep on your back or stomach, a firm bed helps prevent your back from sagging.

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 it is more contouring around the shoulders and hips and has 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.

Most soft mattresses are made with memory foam, polyurethane foam, or a blend of the two. These two materials are great for pressure relief and they can be manufactured to be ultra-plush and soft. Latex hybrid mattresses, on the other hand, tend to be the firmest. 

If you strictly sleep on your side, a soft mattress will cradle your curves and give under your hips and shoulders to promote a neutral spinal alignment. When you're sleeping on your back or stomach, a soft mattress allows your spine to sag into the bed. Beds that offer more support have proven to be more beneficial for people with back pain. If you want a bed that offers plushness and support, go for a medium firmness level. 

Side sleepers tend to benefit from soft mattresses the most because they need a firmness profile that cradles the joints around your hips and shoulders. A firm mattress offers little to no give around the shoulders and joints, which can throw off your spinal alignment and cause back pain. People under 150 pounds also like mattresses on the soft side because they exert less pressure onto a bed, making it feel firmer than what your average-weighted sleeper feels.
