Side sleepers generally prefer medium to soft mattresses for pressure relief on shoulders and hips. However, some side sleepers on the heavier side may benefit from a firm mattress to avoid sinking too much.
Do firm memory foam mattresses sleep hot?
Traditional memory foam can retain heat, but many modern firm memory foam mattresses incorporate cooling technologies like gel infusions, breathable covers, or open-cell foam to mitigate heat retention.

Quality firm memory foam mattresses last 7-10 years with proper care. CertiPUR-US certification ensures durability, and materials like high-density foam or latex may extend lifespan.
