Whether you prefer side, supine, or prone sleeping position, this mattress is right for you.
- 【Cooling Effect & Heat Dissipation】: Sersper CertiPUR-US certified breathable foam keeps you cool when you sleep. Fiberglass-free inner knitted fabric cover also helps air circulate and dissipate heat from the surface of the hybrid queen size mattress. You’ll stay cool and comfy all night.
- 【Motion Isolation & Alignment Support】: Individually wrapped pocket innersprings rebound independently to avoid motion transfer between partners. No disturbance and wake-up will be caused by tossing and turning on Sersper 12 inch queen bed mattress. The supportive foam layer is contoured to your body for edge-to-edge support and resistance of rolling and sagging.
