Sleep soundly outside with the Coleman SupportRest Double-High Air Mattress, Twin, Black. Camping in the backyard or at the campground The SupportRest Double-High Air Mattress with Built-In Pump, Twin inflates in less than 4 minutes. Getting in and out of the bed is easy because of the extra height. The antimicrobial sleep surface resists odor, mold, mildew, and fungus for peace of mind. Thanks to the Double Lock valve that stops air from escaping when the pump is removed and the factory-tested AirTight system, the air bed is leak-free. When it's time for bed, the ComfortStrong coils offer better support for a good night's sleep.
