Wht is great about this bed frame is that you can literally hide your bed away when not in use. This is perfect as a guest bed. In fact, it has become so popular, the item has been sold out and availability must be inquired from first.

This is the heavy-duty steel frame that elevates an inflatable mattress 20 off the ground, making it easier for guests to climb in and out of bed, and raising the mattress above cold, drafty floors for increased comfort. The frame unfolds and sets up in two minutes, then collapses into a compact cylinder that slides into the included storage bag for convenient portability. Durable nylon webbing provides an even surface to support your inflatable bed, and the frame has a mattress enclosure that keeps the air-filled mattress from shifting on the frame. Imported. Queen. Supports 450 lbs. Unfolded: 52 W x 791/2 L. (25 lbs.)
