The ALPS Mountaineering Vertex Air Bed is a great sleeping option whether you have out-of-town guests staying for the weekend or youre 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 nights 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.
