Kelty"s new PVC-Free Sleep Well air beds are not only greener. they stretch less, weigh less, withstand higher levels of abrasion, and provide you with a comfortable and stable nights rest. On a traditional PVC airbed, the PVC stretches when warmth and weight is applied, giving you the feeling that the bed is losing air or has a hole in it. In reality, the volume is increasing on the bed while the pressure remains the same. With TPU, that problem is solved since warmth and weight don"t affect it the same way it does PVC. The circular coil design will give you support and make the Sleep Easy feel like your bed at home. Includes a repair kit and a Kelty Binto storage bag.
