What Defines a Memory Foam Mattress
Memory foam is a viscoelastic polyurethane material that responds to body heat and weight. It slowly conforms to the sleeper, then gradually returns to its original shape. This process aims to reduce pressure points and limit motion transfer between partners.
Top-Rated Models in 2015

How to Choose the Right Firmness
Firmness depends on body weight and sleep position. Lighter sleepers often prefer softer layers, while heavier individuals may need a denser, more supportive base. Side sleepers usually benefit from deeper contouring, while back and stomach sleepers may choose a firmer feel. Always check the return policy and trial period before buying.
