The Intex Supreme Air-Flow Raised Queen Air Mattress is a best seller for many reasons. The main feature of this air mattress is its unmatchable comfort and stability. The ultra-soft surface is made with unique double-layered chambers. Even at 20 inches off the ground, its intended design allows the air to flow gradually throughout the bed. This makes all sides of the air bed completely stable, which ensures that each guest is not disturbed by another guest during the night. Even on the outer edges, the bed will not cave in, so it's perfect for those side sleepers. For setting up this air bed, there is a handy two-way pump, which inflates or deflates the bed. Fitted queen sheets won't slide off with the deep indentations around the mattress.
