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 a durable, lightweight and completely PVC-free fabric. The coil system used 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 bed is included for easy storage and transport. The Vertex is available in a Twin or Queen size.
