The ultimate in versatility: use the Coleman 4-in-1 Quickbed as two separate twins, zip them together to make an instant king-sized bed, or zip, snap and stack them for a luxurious double-high twin! Each twin measures 74" x 39" x 5", with durable inner coils to provide strength & firmness. The 4-in-1 Quickbed is durably constructed of heavy-duty, puncture-resistant PVC, with a soft suede top for extra comfort. The Quickbed is easy to inflate and deflate, thanks to Coleman's extra-wide Advanced Double Lock Valve. Like all Coleman inflatable products, this Quickbed features Coleman's Airtight System, guaranteed not to leak. And the built-in Wrap 'N' Roll storage system makes packing and storing quick and easy.
