Best Mattress for Side Sleepers 2025

What to Look for in a Mattress for Side Sleepers

Your preferred sleep position plays a big role in determining which mattress is most suitable for you. While the amount of support you need and what you consider comfortable can vary from someone else, side sleepers often consider these features when mattress shopping online:

Medium Feel

Many side sleepers find mattresses within the medium firmness range balance comfort and support. This range includes medium-soft, medium, and medium-firm. Along with sleep position, body type and personal preference also can affect what mattress firmness to pick.

For example, an average-weight side sleeper may find a medium to medium-firm mattress prevents sinking, cushions pressure points, and supports spinal alignment for greater comfort. Meanwhile, a lightweight side sleeper may find medium-soft has enough contouring to relieve pressure on shoulders and hips. Medium-firm or firm typically suits plus-size people while side sleeping.

Pressure Relief

Another common feature in the best mattress for side sleepers is pressure relief. When curled on your side, your hips and shoulders bear most of your body weight. These sensitive areas require cushioning and support, or discomfort, pain, and spinal misalignment could result.

A mattress with good pressure relief for side sleepers gently cushions the side sleeper’s hips and shoulders. The body sinks slightly into the sleep surface, but not excessively, enabling your body weight to spread evenly across the mattress, lowering the risk of pain.

Spinal Alignment

When sleeping on your side, finding a mattress that keeps the spine in neutral alignment is also important. Ideally, it supports the natural curve of the back when lying on your side, without arching the back, as that could lead to back strain and morning stiffness. A mattress that aligns your spine properly while in your favorite sleep style may prevent back and neck pain, as well as improve sleep quality as you are less likely to toss and turn because you’re uncomfortable.

Based on our team’s research, we consider Canada’s best-selling Nectar Memory Foam Mattress advantageous for many side sleepers. Also known as The Nectar Mattress, we consider it a standout for many reasons.

Medium-Firm

As earlier explained, a medium feel suits a lot of side sleepers. This Memory Foam Mattress is a 6.5 on the firmness scale, per Nectar Canada’s site. A 6.5 is typically medium-firm.

This mattress is neither the softest (1) nor the firmest (10). Instead, it is a bit firmer than medium (5) while and offers pressure relief and contouring. A medium-firm mattress can be a good fit for several average-weight and plus-size sleepers who prefer lying on their side. In addition to sleep style and body type, personal comfort preference affects whether you like medium-firm or not.

5-Star Ratings

There are more than 1,700 five-star ratings on Nectar Canada’s website for its Memory Foam Mattress from reviewers who say they are side sleepers. There’s reassurance in seeing this positive feedback from buyers. Among the buyer reviews are the words comfort, coolness, and supportive. While we cannot guarantee it suits every side sleeper, it’s great to know that many singles and couples are happy with their purchase.

Ultimate Comfort

If an all-foam mattress is what you grew up sleeping on, The Nectar Mattress will likely feel familiar, with the added potential for exceptional comfort with three premium foam layers. This mattress’s 2-inch memory foam layer hugs the body with a cloud-like feel, superior body contouring, and gel infused into it for cooler sleep. Below are two conventional foam layers for greater support, airflow, and durability.

Pressure-Relieving Support

Greater comfort can come from having enough support and pressure relief in a mattress. The plush memory foam cradles the body’s unique curves, cushioning the shoulders and hips to help relieve pressure where side sleepers often need it most. That may prevent stress and pressure buildup in these areas during the night, which might otherwise wake some sleepers up due to discomfort.

Spinal support is also important for side sleepers, as earlier described. Quality memory foam, like in this Nectar Canada mattress, allows heavier areas like the shoulders and hips to sink a bit while still encouraging neutral spinal alignment with the help of the responsive foam layer below it. That helps prevent some side sleepers from feeling achy or stiff the next morning.

Cooling Features

A cooler sleep can be more comfortable, especially if you are prone to overheating. That might prompt you to look for a mattress with better breathability and cooling capabilities. The Nectar Mattress has received reviews online from side sleepers who describe this mattress as regulating temperature effectively and staying cool throughout the night.

Those who regularly sleep hot may find relief from the gel-infused memory foam. This layer offers some people a cooler sleep than traditional memory foam. Above it, Nectar’s signature cover incorporates cooling technology; heat-absorbent polyethylene fibers whisk heat away from the body to combat overheating. Finally, the mattress’s third layer allows airflow; a more breathable mattress encourages longer sleep by regulating body temperature.

What Else Impresses Us about The Nectar Mattress

Motion Isolation

While perhaps not the first thing side sleepers look for when mattress shopping online, this feature matters for many couples. The quality memory foam in this Nectar Canada mattress has great motion isolation. That means side sleepers (and anyone else) are less likely to feel their partner move; that encourages uninterrupted sleep.

• Twin: 38” W x 75” L
• Twin XL: 38” W x 80” L

It ships free across Canada, too, saving you that extra fee. Nectar Canada also includes a risk-free 365-night sleep trial with the Memory Foam Mattress, going well beyond the industry average. That’s plenty of time to try the mattress at home for as long as a year, and, in the unlikely case you’re not fully satisfied, you can return it for free by meeting the policy guidelines.

Warranty protection further enhances mattress value. Nectar Canada includes a Forever Warranty™ with the Memory Foam Mattress. That helps protect you as the original purchaser against certain mattress defects in material and workmanship, with repair or replacement as set out in the warranty terms.
