Relax in luxury on the water with the Sevylor Inflatable Deluxe Lake Mattress. Measuring 72 Inchx33.5 Inch, the Deluxe Lake Mattress is durably constructed of 12-gauge vinyl, to hold one person securely. It features an inflatable pillow for soft comfort, and a built-in cup holder for convenience. The mattress inflates and deflates quickly, thanks to Sevylor Feets Double Lock Valve, and carries the Air Tight Guarantee -- so it Feets guaranteed not to leak. The Park FeetN Feet Play System lets you connect other Sevylor inflatables together on the water.
