Comfort	Our 7-layer hybrid mattress fuses the springy support of individually-wrapped coils with the plush comfort of gel memory foam. Experience out-of-this-world comfort, with the best of both worlds. Two one inch layers of special gel-infused Memory Foam absorbs and dissipates body heat as fresh air passes through the foam.	Every iComfort mattress is made with our exclusive Carbon Fiber Memory Foam. This system channels heat away from your body and provides exceptional strength for back and neck.
Support	The core of the GhostBed Flex features the patented Ghost Flex innerspring coil unit with our Spirited Edge Support design. Individual 8.5" 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. One inch of Ghost Flex Soft Transition Foam offers pure pressure relief. This layer of soft transition foam contours to your body and reduces the need to toss and turn. Individual coils offer the responsive support of traditional innerspring mattresses, without the worry of wearing out after just a few months. Additionally, the coils near the edge of GhostBed Flex are specially reinforced for better support - so you can sit on the edge of your bed without sliding off.	With iComfort, multi-layered mattress-cooling foam technology adds support, resilience, and temperature regulation for the coolest, most comfortable sleep ever.
