TOUGH PRE-TESTED VINYL WITH A VELVETY FLOCKED SURFACE: The airbed is made from tough pre-tested vinyl to withstand a heavy amount of wear and tear. In the unlikely event that it does get damaged, a repair patch is conveniently included. The airbed has a velvety soft flocked surface to provide superior comfort with or without a bedsheet.COIL-BEAM CONSTRUCTION FOR ULTIMATE SUPPORT & STABILITY: Unlike many inflatables, the airbed has a robust coil beam construction. As the bed is inflated, the internal coil beams harden to provide the support and stability of a real mattress. The result is a more comfortable sleep, free from the aches and pains that are common with sleeping mats.ONE-WAY SCREW VALVE FOR FAST INFLATION: A one-way valve allows you to rapidly inflate the airbed without it losing any air. Simply unscrew the top cap and attach a pump to inflate. Remove the middle cap to allow air to escape and deflate the airbed. Can be inflated in under 3 minutes using an AC Pump (not included) but takes longer with a manual pump.
