Side sleeping is the most common position in the UK, but it puts extra pressure on the shoulders and hips. The best mattress for a side sleeper needs to cushion these pressure points while still supporting the spine in a neutral position. We have filtered our database of 200+ mattresses to find the ones that offer the best combination of softness, pressure relief, and support for side sleepers.
When you sleep on your side, your body weight concentrates on a smaller surface area compared to back or stomach sleeping. Your shoulders and hips bear the brunt of this pressure, and if the mattress does not contour around them, you can wake up with numbness, tingling, or aching joints.
The ideal mattress for side sleepers is typically medium to medium-soft (4 to 6 out of 10), with enough give in the comfort layer to let the shoulder sink in while keeping the spine aligned from neck to tailbone.
Memory foam is often the top choice for side sleepers because it moulds closely to the body, filling the gaps at the waist and cushioning the shoulders. Look for at least 5cm of memory foam in the comfort layer for adequate pressure relief.
Hybrid mattresses with a plush memory foam or latex top layer also work well. The pocket springs underneath provide support and prevent excessive sinking, while the foam layer handles pressure relief. This combination is particularly good for side sleepers who also want decent edge support and ease of movement.
Even the best mattress cannot fully compensate for the wrong pillow. Side sleepers generally need a thicker pillow (12-15cm) to fill the gap between the shoulder and the ear, keeping the neck in line with the spine. If you invest in a new mattress, consider reviewing your pillow at the same time.
Most side sleepers do best with a medium to medium-soft mattress (4 to 6 out of 10). This allows the shoulders and hips to sink in enough to keep the spine aligned. Heavier side sleepers may prefer a medium firmness to prevent excessive sinking.
Memory foam generally performs better for side sleepers because it contours closely around pressure points. However, a hybrid mattress with a thick foam comfort layer can offer the same pressure relief with added support and breathability.
Shoulder pain from side sleeping usually means your mattress is too firm. The shoulder cannot sink in far enough, creating a pressure point. A softer comfort layer or a mattress with zoned support (softer at the shoulders) can resolve this.
