A 3-layer construction:
| Designed to exceed the performance of fine luxury hotel mattresses and $4,000 in-store brands, the GravityLux Medium is constructed with the following layers:
|
Comfort Info | |
3 lb density memory foam rebounds (takes it shape) quicker making it easier to change positions. | Each tiny cell acts like an individual shock-absorbing cushion, releasing air independently as pressure increases, and ensuring individualized comfort and support. |
Support Info | |
Our CoolRest™ gel advanced memory foam quickly conforms to your body for pressure relief and support without letting you sink too far into the mattress. | The GravityLux features 7 progressive layers of support, relieving pressure through the hips and shoulders and providing enhanced support through the lumbar and lower back. We achieve this through a proprietary foam texturization and fabrication process. |
Comfort Specs | |
Open cell memory foam increases air flow, contributing to a cooler sleep. | Unlike traditional memory foam, AirCell™ isn't temperature sensitive, and dissipates body heat faster. It draws heat from your body, dispersing it throughout the mattress to keep you cool. |
Support Specs | |
CoolRest® Gel memory foam perfectly contours to your body providing improved pressure relief to reduce tossing & turning. | A two-layered Gel Foam top ensures your back, hips and shoulders get exactly the right level of cushioning and support, easing stress and muscle tension. |
Fabric Specs | |
The TENCEL® cover offers unique moisture management properties - absorbs 50% more moisture than cotton, making it a highly effective performance fabric. Rapid absorption of moisture proves most effective in inhibiting bacterial growth naturally, without adding any chemicals. | Sleep cool and dry with our Eucalyptus-derived TENCEL® cover. Tufted with 2" of premium cooling gel foam inside, it enables airflow and wicks away body heat and moisture. |
