Most people sleep on their side – roughly 50–75% of the population. This makes finding the right mattress crucial: side sleepers need pressure relief for hips and shoulders and spinal alignment. Without it, you risk back pain, uneven pressure distribution, and a generally uncomfortable night’s sleep. This article reviews the top 12 mattresses tested by sleep science experts, focusing on models that balance support and cushioning.
Why Side-Sleeping Matters
Side sleeping isn’t just a preference; it’s a biomechanical reality for many. Unlike back or stomach sleeping, side positions place concentrated weight on pressure points. A good mattress counteracts this by conforming to the body’s curves while preventing excessive sinking. This is where hybrid, memory foam, and cooling technologies come into play. The goal is the “trifecta” of lumbar support, pressure relief, and overall comfort.

The responsive coil core also helps regulate temperature.
