Air Mattreses

Air mattreses are better than sleeping on the ground if you're camping, and they're tolerable for sleeping on if you have company for one or two nights. But they aren't good for more than that if you have any back problems.

And do they come in king size? Because I haven't seen any larger than queen. And for me, queen just isn't good enough for two people, at least not if I want to sleep like I normally do in my real bed. And if there are three cats on it with my and someone else.
