Support	The core of the GhostBed Flex features the patented Ghost Flex innerspring coil unit with our Spirited Edge Support design.

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.	Multi-layered foam technology adds support, resilience, and temperature regulation for the coolest, most comfortable sleep ever. Carbon Fiber Memory Foam provides exceptional strength for back and neck support. Air Support Foam (used only in CF4000 model) moves with your body and contours around it to help alleviate aches and pains caused by pressure points.
