Firmness and Support
Medium firm is a versatile choice. It suits back and stomach sleepers. Side sleepers may need extra pressure relief. Look for a mattress with a high-density base. This prevents sagging and extends lifespan.
Cooling Features
Memory foam often traps heat. Gel infusions help dissipate warmth. Some models use breathable covers or airflow channels. If you sleep hot, prioritize cooling tech. Check the foam density, as denser foam retains more heat.
Thickness and Materials
Thickness ranges from 8 to 12 inches. Thicker mattresses usually offer more support. Look for multiple foam layers. A comfort layer of 2 to 3 inches provides contouring. The base layer should be at least 6 inches of high-density foam.
Edge Support and Motion Isolation
Strong edges make getting in and out easier. Foam mattresses often lack edge support. Hybrids with coils perform better. Motion isolation is key for couples. Memory foam excels here. Test these aspects if possible.
