The Simmons Beautyrest Fusion Aire 18" Raised Queen Air Bed Mattress with Built-in Pump provides firm support all-night long. The PolyFusion is three times better than a vinyl air bed. It combines the flexibility of premium poly vinyl with the strength and durability of Poly-Tex fibers, creating a real mattress-like feel that can maintain a firmer feel throughout the night. The never-leak PolyFusion creates an airtight barrier that keeps air in and prevents the mattress from stretching or losing pressure while you sleep getting your Beautyrest. Air stays in so you stay asleep. No need to add air to your bed during the night or be woken up by a pump that kicks on and vibrates. The built-in pump makes it easy to inflate and deflate your bed quickly. Get your Beautyrest with this never-leak technology.
