This is a handy idea: an air bed designed for the the backseat of a car or SUV. The mattress includes an inflatible base that levels out the mattress, and a bit of extra cushioning to cover the console. The whole unit measures 35x57 inches.

This inflatable mattress would be great for camping, festivals, or anything of the sort where you might want a bed that didn't have to be inside of a tent.
