Do not buy this bed! Not because it isn't comfortable, because it is. Don't buy it because it's crap! The wonderful folks at Zappos have replaced it for me twice as the first one was wouldn't hold air right out of the box. The second developed a bad leak in a couple of months, and the current one, yes number 3, just started leaking today at almost 5 months out. I use it as my daily bed. Don't do it unless you're a glutton for punishment like I am. I have had excellent luck with the other models I have had for years without incident. There is one in my guest room and one on my motor
home, and they hold air just fine. This one is just a dud.
