Rest easy knowing you"ll enjoy an exceptional night"s sleep on the Lightspeed Outdoors Deluxe TPU Air Bed with Battery-Operated Pump due to the patented stabilizer system, using 192 independent connectors between the top and bottom layers, providing adjustable but even firmness. TPU also does not stretch like PVC, which means minimized movement disturbances between partners. Mattress firmness can easily be adjusted from soft to very firm depending on preference, using the included battery-operated pump and built-in Boston valve. The bed fits queen-sized sheets and comes with built-in handles for easy carrying and an oversized storage bag for frustration-free packing. This deluxe air bed is lighter, more durable and less prone to stretching or ballooning in comparison to traditional PVC air mattresses thanks to the superior TPU (Thermoplastic Polyurethane) material used in its construction. At only six pounds, this portable mattress is less than half the weight of most air beds and packs considerably smaller than traditional air beds, making it convenient for travel and storage. While light weight, TPU is exceptionally tough, with great abrasion and puncture resistance that helps to insure leak-free reliability.
