The mattress needs of side-sleepers are different than those of back- and stomach-sleepers.

The most important difference is that sleeping on your side creates sharper body angles and deeper pressure points that the surface of a mattress must contend with. This is why side-sleepers need more compliant surfaces that also provide excellent support without ‘bottoming-out'.

Side sleepers are also more likely to move around at night as they switch positions, so motion transfer can become an issue when two partners share the bed.

In this updated Best Mattress Guide, we've used these requirements to select the best online mattresses for side sleepers in five different categories:

What Do Side Sleepers Need in a Mattress?

There are 13 key features you should consider when buying a mattress online (see the complete list).

But of these, three are the most important to side-sleepers: support, firmness and motion transfer.

1. Excellent Support

Best Mattresses for Side Sleepers - spinal zone support

Good support is the most important mattress requirement for side sleepers.

Good support means that your body’s weight is spread out as evenly as possible on the mattress surface, to eliminate pressure points – especially at the hips, shoulders and neck.

It is extremely important that the back, spine and neck also be supported in the right alignment.

For side-sleepers especially, a mattress with poor support is not only bad for your sleep, it is bad for your health.

2. Soft-to-Medium Firmness Level

Due to the sharp contours that must be supported, a soft to medium firm mattress is best for most side sleepers.

A softer mattress provides sinkage to allow for proper contouring around the body's shoulder and hip regions.

If the mattress is too firm, shoulders and hips cannot sink enough into the mattress, leading to an unnatural spinal position and uncomfortable and harmful pressure points.

3. Limited Motion Transfer

Best Mattresses for Side Sleepers - notion transfer

Most side sleepers turn from side to side while asleep, usually without realizing it.

For couples, this can be a real problem, as motion from one side of the bed causes a disturbance on the other side.

These days, many mattresses sold online are equipped with technology that limits motion transfer.

For example, some mattresses make use of individually-wrapped coiled springs while others use special types of foam to insulate partners from each other's motions.

Of course, these are not the only things side sleepers need in a mattress; other aspects such as cooling, breathability and moisture control are also important.

But support, firmness and motion transfer are the top three.

The Best Online Mattresses for Side Sleepers

Mattresses with a soft or medium firmness and moderate sinkage minimize pressure points on shoulders, neck and hips.

Mattresses with minimal motion transfer reduce the risk of waking your partner when you switch sleeping positions at night, which side-sleepers shift tend to do more frequently than others.

Best Memory Foam Mattress for Side Sleepers: Alexander Signature Series (Medium)

Nest Alexander Signature Select mattress review - woman on side in showroom

Memory foam is well-known for its ability to contour around a body, which minimizes pressure points and provides outstanding support.

For side-sleepers looking for a great memory foam mattress, our top recommendation is Nest Bedding’s Alexander Signature Series.

We specifically recommend the medium comfort level.

The Alexander Signature Series uses five layers of CertiPUR-US certified foam.

A 1.5-inch soft quilted cover gives the top a comfortable, plushy feel.

Below the top, Nest adds three layers of specialized foams, including:

  • a gel memory foam layer for temperature control
  • a Visco memory foam layer for support and contouring and
  • Nest's unique Smartflow Air Flow Foam for support and breathability.

The result is a mattress that provides exceptional performance in the areas of contouring, support, breathability and cooling.

Solid Edge Support Base layer is also built into the mattress to limit edge depression and provide extra support for couples who sleep near the edge.

On a scale of 1 to 10, from rock-hard to cloud-soft, the Alexander Signature Medium delivers a firmness level of 6 out of 10. This is about perfect for most side sleepers.

The Alexander Signature Series is priced a bit on the high side, however. A Twin costs $999, a Queen is $1,299 and the largest California King costs $1,499. This is slightly higher than many online mattresses – but well worth the cost.

The Signature Series mattress comes with an exceptionally long Lifetime warranty, a Lifetime Comfort Guarantee and a 100-night trial.

Best Latex Mattress for Side Sleepers: Brooklyn Bedding

Brooklyn Bedding BME - hero shot

Latex is a common material used in manufacturing mattresses. There are two main types of latex used in manufacturing today: Dunlop latex and Talalay latex.

Latex is generally considered to be a better material for temperature control and support. It is also provides a unique bounce, something that is absent in most memory foam products.

For our pick of the top latex mattress for side sleepers, we recommend Brooklyn Bedding's #bestmattressever.

BB offers their mattress in soft, medium and firm comfort levels. We'd recommend the soft and medium #BMEs for side-sleepers.

Brooklyn Bedding BME - mattress constructionThe Brooklyn Bedding mattress starts with an ultra-soft and highly-breathable quilted cotton cover at the top.

A second layer of Talalay latex provides the necessary support and contouring that side sleepers need.

The third level is a transition layer of Dunlop latex, which provides an additional layer of support so that a side-sleeper's body profile doesn't “bottom-out”.

For the foundational base, there is a layer of high-density poly foam, which ensures the mattress lasts for years without degradation or sagging.

Overall, Brooklyn Bedding's #BestMattressEver performs very well in the areas side sleepers care about most: support, firmness, motion transfer and cooling.

The #BME is offered in a number of sizes including a Queen Short ($750), Full XL ($700), Twin XL ($475) and a split California King ($1,050).

Brooklyn Bedding offers an industry-standard 10-year warranty and a 120-night trial.

Brooklyn Bedding's #BME is available for sale on their website and on

Best Innerspring Mattress for Side Sleepers: Saatva


For a time, innerspring mattresses were the most popular type sold.

Today, however, memory foam and latex mattresses have taken the helm.

Though no longer as popular, innerspring mattresses do retain a number of advantages over foam. They generally provide excellent support, especially edge support. Unlike most foam mattresses, innerspring mattresses also provide a noticeable bounce, which makes them the best type of mattress for sex.

Our top innerspring mattress recommendation for side sleepers is Saatva.

Saatva is the same company that owns the popular Loom and Leaf foam mattress brand.

One of the best-known online mattress brands, Saatva has not spared anything in creating the perfect innerspring online mattress.

The Saatva mattress uses an advanced coil-on-coil system to provide outstanding support and durability.

The lower, hourglass-shaped, coil unit is for foundational support.

Saatva mattress review - CUTAWAY - BY CONSUMER REPORTS

The upper coil unit features individually wrapped steel coils. Wrapping the coils individually helps the Saatva mold itself to contour to any body shape, which is really important for side sleepers.

Another benefit of Saatva's coil-on-coil system is the almost complete elimination of motion transfer, since movement is not transmitted from one individual coil to another.

To ensure all-over support, Saatva uses a dual-edge support system, which increases the useful sleeping surface area and prevents sagging.

But what makes the Saatva mattress one of the most comfortable mattresses we've ever tested is their unique Euro pillow top. With its plush filling and organic cotton cover, side sleepers will have no trouble at all staying planted and getting a cool and restful night's sleep.

Three Firmness Levels

Saatva offers three firmness levels: plush soft, luxury firm and firm.

For most side sleepers, we recommend luxury firm. It has the perfect balance between support and contouring.

If you need something extra soft, then try the Plush Soft.

Saatva offers plenty of sizes to choose from, including custom sizes. Prices range between $699 and $1,299. The popular Queen Size mattress costs $899.  All Saatva mattresses are sold online via their website.

Saatva mattresses come with a better-than-average 15-year warranty and a no-risk trial period of 75 nights.

Saatva doesn't normally offer discounts or coupons. You will always find the best price on their website.

Best Organic/Natural Mattress for Side Sleepers: PlushBeds Botanical Bliss

PlushBeds Botanical Bliss Mattress Review - organic cotton top corner view

Organic mattresses are built to stricter standards than other mattresses.

Every process, from the raw materials selected to how the mattress is manufactured, is monitored to ensure that no harmful chemicals are used.

The result is a mattress that is better for your health and the environment.

Organic and natural mattresses also tend to be more expensive.

For most side sleepers, PlushBeds Botanical Bliss Organic Latex Mattress is a great choice. It is often recommended by chiropractors and orthopedic specialists, thanks to its excellent level of support and pressure-relieving capabilities.

The Botanical Bliss is topped with a breathable organic cotton cover.

PlushBeds Botanical Bliss Mattress Review - eco certifications

Beneath the cover are a pure Joma New Zealand wool mattress cover, a Talalay latex comfort layer and an organic Dunlop latex core. These unique organic materials offer additional benefits, as Joma wool and Talalay latex are both dust mite resistant and mold and mildew resistant. Joma wool is also naturally fire resistant.

The Botanical Bliss performs very well in temperature control, support, comfort and breathability.

As for firmness, there are four levels to choose from. We recommend the soft or medium firmness level for side-sleepers.

The Botanical Bliss mattress is available in all the usual size options, with prices ranging from $1,199 for a Twin size to $2,099 for the California King. You can purchase the Botanical Bliss mattress on PlushBeds website.

Yes, it's expensive for an online mattress – but not expensive (at all) for an organic one.

You can also opt for the split option available in Queen, King and California King sizes.

PlushBeds' warranty lasts a generous 25 years, while the trial period is 100 nights.

Best Custom/Split Mattress for Side Sleepers: Helix Mattress

Helix mattress - edge sinkage

For those who need a custom, made-to-order mattress, Helix Mattress is your best online option.

Couples with different mattress preferences often order split or custom mattresses, because the mattress can be split with one side being firmer or softer than the other.

Helix really takes customization to the next level with its totally unique online ordering process.

Helix mattress review - online configurator

Customers complete a quick online questionnaire that provides key inputs including height, weight, sleeping position and sleeping preferences, which include the following 4 factors:

  1. feel (soft to firm)
  2. support (light to strong)
  3. temperature regulation (mild to cool) and
  4. contouring or elasticity (low to high).

These responses are used to create a unique sleeping profile for each sleeping surface, which is then used to manufacturer a custom mattress.

Helix made-to-order mattresses are delivered 7 to 10 business days after ordering – which is remarkable, when you consider that many online mattress companies who don't offer customization take about the same amount of time.

As far as mattress construction goes, Helix uses Dunlop latex for bounce and airflow, micro coils for weight distribution and contouring, and high-density foam for premium base support.

Available for sale only on their website, Helix offers all standard mattress sizes, from Twin to California King. Prices range from $600-$995, in the mid-range of online mattresses. Higher than bargain brands like Tuft and Needle, but less than luxury brands Nest, Saatva and Keetsa.

Every Helix mattress comes with an industry-standard 10-year warranty and a 100-day no-risk-return trial.

At the moment, there are no discounts or coupons available on the Helix main site – but you can use our exclusive coupon to take $50 off.  To learn more, click on the coupon below.

How We Rate Mattresses for Side Sleepers

How To Buy a Mattress Online Infographic (intro)
13 Features That Matter (Infographic)

Here are the 13 factors will look for in mattresses when rating them:

1. Brand

Saatva and Casper are widely credited with starting the modern online mattress revolution. Today, there are dozens of brands selling quality mattresses.

Some of the top brands include Brooklyn Bedding, Casper, Saatva, Nest bedding, Leesa and Keetsa. Some are established companies like Saatva, while most are startups like Casper.

All things equal, we prefer established brands over startups because their warranties have more experience and capital standing behind them.

2. Price

Online mattresses are typically 30 to 50 percent cheaper than store-bought mattresses. When rating mattresses, we consider mattresses that are high quality but still affordable. We also consider any discounts and coupons offered by companies.

3. Firmness and comfort choices

With so many companies today, there is a mattress available for sale online to suit anyone. Side sleepers can easily find their perfect firmness level to ensure maximum sleeping comfort.

4. Mattress construction

How a mattress is constructed contributes greatly to the sleeping experience and its useful life. We look for things like materials used, the number and function of different layers and any unique technology used.

5. Heat transfer

The right temperature range for proper sleep is mild to cool. To accomplish this, it is important for a mattress to dissipate heat from the surface efficiently.

6. Motion transfer

Motion transfer is an important issue for many couples who sleep together. The less motion can transfer from one point on the mattress to another, the less one sleeping partner can disturb the other.

7. Sinkage

Side sleepers typically require more sinkage than back and stomach sleepers. In our evaluation, the amount of sinkage of a mattress says a lot about its comfort level.

8. Eco-friendliness

The use of organic and eco-friendly materials is not just for the environment, but also for the health of the people who sleep on their sides. While not every online mattress will be certified organic, most mattresses today are CertiPUR certified, meaning they lack dangerous chemicals.

9. Off-gassing

Though not dangerous, off-gassing can be a bother for people who are smell-sensitive. We check how much off-gassing different mattresses undergo after unpacking. Most foam mattresses will emit a slight amount of off-gassing for a few days, while they decompress. Inner spring mattresses emit none.

10. In-home trial

One major advantage of buying a mattress online is that you and your partner get ample time to try it out in your own home. The standard trial period in the industry today is 100 days, though it can go as low as 75 days and as high as 200 (more than 6 months!).

11. Return policy

Most online mattress companies offer a risk-free return policy and provide free return pickups. It is nevertheless important to understand the return policy of a specific seller before making a purchase, because some companies will not accept a return unless the mattress has been used for a minimum number of nights. Other companies may not accept a return if there is a particular kind of damage to the mattress.

12. Warranty

A company's warranty is the best sign of a mattress company’s trust in its product. Most warranties run for 10 years. Some have 15, 20 or 25-year warranties. Warranties differ mostly in the types of damage covered, and whether the warranty is prorated (refund value declines over time) or not.

13. Delivery and setup

How many days does it take to deliver the mattress? Are there any shipping costs? Does the company help in setting up the mattress at no charge (white glove service)? These are some of the questions we ask when rating mattresses for delivery and setup.
