They are excellent. So too is their double comfort high - just took delivery of one this week and it is extremely comfortable and easier to get in and out of (if you have a bedroom inner tent big enough), also is 5ft wide instead of 4'6".
I have just bought a 2nd Coleman to put on top of our first to make it double height. My poor old back is no longer up to getting on and off the floor so I'm hoping this will help. I'm taking some velcro in case they slide about so I hope this is the answer to my problem because the Coleman is a very comfortable airbed.
