The ALPS Mountaineering Vertex Air Bed is a great sleeping option whether you have out-of-town guests staying for the weekend or you're camping in the great outdoors. It is constructed of durable, lightweight, and completely PVC-free fabric. The coil system makes a solid and comfortable sleeping surface for a great night's sleep. Unlike most other rechargeable pumps, our innovative pump supports pass-through charging, which allows you to operate the pump with the included wall or car chargers regardless of if the battery is fully charged or not. The pump quickly inflates/deflates your air bed with the 'flip of a switch.' A convenient carry bag is included for easy storage and transport. The Vertex is available in a Twin or Queen size. 7612102 Blue Twin 7632102 Blue Queen
