6 Great Guest Beds
Great for: Kids. Just add a couple of flashlights and this cot and air bed will make a kid feel as if he's camping out. The two-inch-thick inflatable mattress, slightly longer and narrower than a standard twin, can be used alone or with the aluminum cot frame, which folds down for storage.
