What to Look For
Memory foam mattresses under vary in thickness, density, and firmness. Thickness usually ranges from 6 to 12 inches. Higher density foam lasts longer and offers better support. Check the CertiPUR-US certification for safety. Consider your sleeping position and body weight.
Firmness and Support
Firmness is a personal preference. Side sleepers often prefer a softer feel to relieve pressure. Back and stomach sleepers usually need a firmer surface for alignment. Medium-firm is a safe middle ground. Heavier individuals may need a thicker mattress to avoid sagging.
Cooling Features
Memory foam can trap heat. Gel-infused foams help dissipate body heat. Some mattresses have breathable covers or airflow channels. If you sleep hot, prioritize cooling features. Look for open-cell foam or phase-change materials.
Durability and Warranty
Budget mattresses may not last as long as premium ones. Check the warranty length, typically 5 to 10 years. Read owner reviews for reports of sagging or indentations. A higher density foam base often improves durability.
