Take the comfort of an indoor bed with you when you sleep outside on the twin size Coleman Signature Rugged Bed. The durable air mattress has a 25 percent thicker, heavy-duty bottom and offers extra support. Keep that perfect firmness all night long with the Double Lock valve, and when you're ready to pack up, that same valve deflates the mattress quickly. The built-in patented Wrap 'N' Roll storage system makes putting it away a matter of folding it, rolling it and storing it in the included carry bag. Extra-heavy-duty PVC with 32 inner coils to provide strength and firmness. Thick PVC on bottom make it durable. Uses the Double Lock Valve for fast and simple inflation/deflation. Wrap 'N' Roll Storage System for convenient built-in storage bag.
