Tired of waking up drenched in sweat? Yeah, us too. So we set out to create a mattress that actually works with your body to keep you cool, all night long. The GhostBed 3D Matrix Hybrid is the ultimate sleep upgrade, featuring 7 layers of comfort including our patented gel polymer-our secret sauce for cool, restorative sleep. Did you know that as you fall asleep, your body naturally tries to lower its core temperature? With GhostBed's patented 3D Matrix technology, now your mattress can work with you so you fall asleep faster and stay asleep longer. No more tossing and turning, just comfortable sleep so you can wake up to an amazing morning. (Alarm clock and coffee not included!)With our Spirited Edge support design, you won't have to worry about this all-too-common issue. Individual 6" coils create the weightless feeling you love, while wrapping them individually creates minimal motion transfer. Plus, two rows of specially reinforced coils along the edge of the bed make it easy to sit comfortably without slipping off. Size: medium. Color: White.
