The ultimate in luxury for base campers, the Comfort Deluxe Self-Inflating Sleeping Mat features four inches of plush foam and a 30D stretch knit fabric on the upper surface for a luxurious warm feeling when its cool, and a cool feeling when its hot. The flip-over multi-function valve makes packing up the pad relatively easy because it prevents air from being drawn back in as it's rolled up.Be aware - if you pull out a Comfort Deluxe for house guests, they may end up staying longer than originally planned!
