Buying Guide
- Sleep position and support: If you primarily sleep on your back or stomach, an extra-firm option may help with spinal alignment. Side sleepers often benefit from a balanced or medium-firm feel with good pressure relief.
- Temperature management: Look for cooling covers, gel-infused foams, or breathable pocket-coil designs if you tend to overheat at night.
- Motion isolation: Couples or restless sleepers should prioritize memory foam layers or pocket-coil hybrids to minimize partner movement transfer.
- Edge support: Reinforced edges expand usable surface area, helpful for those who sit on the edge or share a king bed with a larger person.
- Durability and materials: CertiPUR-US certification and fiberglass-free construction are common indicators of safer materials and long-term stability.
