How to Choose The Best Mattress for Side Sleepers UK 2025?

Side sleeping is not only the most popular sleeping position but it’s also thought to offer the most benefits. This sleeping style is also known as lateral position and provides all sorts of benefits from spinal alignment to reduced risk of back pains, snoring, and heartburn. However, these benefits are promised if you’re keen to get the best mattress for side sleepers. Here are the significant considerations to make:

How to Choose The Best Mattress for Side Sleepers UK 2025?

3 Types of Mattresses

Memory foam 

also known as viscoelastic foam, this material is characterized by the ability to compress due to body heat and pressure, so it tends to adapt to your body shape. This behaviour makes foam mattresses the best for side sleepers as they cushion pressure points in addition to keeping the spine aligned. Memory foam also takes the lead in motion isolation, but it’s known to sleep hot.

Latex 

while relatively firmer than memory foam, latex is also known for its pressure-relieving support. Slightly softer latex mattresses are excellent for side sleepers as they are great at keeping the spine aligned. Unlike memory foam, latex does not sleep overly hot. 100% natural latex also offers a superb option for individuals looking for a less toxic bed solution.

Hybrid and innerspring 

hybrid mattresses come with a base of individually pocketed coils and foam layers on top. These mattresses offer a happy medium in terms of comfort, support, and pressure relief. If you’re considering an innerspring mattress, a bed with a pillow top will be more comfortable.

Ideal mattress firmness for side sleepers

Side sleepers need a cushy mattress that lets their shoulders and hips sink slightly for pressure relief. But the mattress shouldn’t be too cushy as gravitational pull may pull their spine out of alignment, causing back pain. This means getting a medium-firm mattress to balance pressure relief with full-body support.  
However, side sleepers should note that the ideal firmness level mainly depends on their weight. The heavier  you are, the firmer the mattress needs to be.

Thickness- does it matter?

While stomach sleepers prefer a relatively thinner mattress, side sleepers will benefit from deep and soft mattresses. In the mattress world, thicker mattresses tend to be softer and, therefore, offer the contour and pressure relief properties that side sleepers look for.
