The best mattress firmness for side sleepers is typically medium-soft to medium-firm, or around a 4 to 6.5 out of 10 on the firmness scale. This range provides enough cushioning for the shoulders and hips to sink comfortably into the mattress, which helps relieve pressure points and reduces strain on joints.
At the same time, a medium-feel mattress should provide adequate support to keep the spine in a neutral position and prevent the midsection from sinking too deeply. The ideal firmness can vary based on body weight and personal preference, but most side sleepers achieve the best balance of pressure relief and spinal alignment with a mattress that offers contouring comfort and supportive underlying layers.
