We've bought from both Kmart and Rays. We got three from Kmart, only one is remaining after not a lot of use. DH and I have one double each and DD has a single. The ones at Rays, well one needed to be patched after the second night of sleeping on it. While we didn't buy Coleman, we did buy a brand name bed from Rats. I honestly don't think it makes a lot if difference, just keep a patching kit handy and a spare. One of ours actually popped and couldn't be repaired.
