We just bought one of those air beds, like the ones witht he sleep number system, but not that brand. We have a 90 night trial period and so far after a month, I don't think that I could go back to my other mattress.Both my wife and I love it. Each side is individually adjustable, mine is set softer than hers. (you can have it really soft, or really firm, change it daily to however you are feeling at the trime.)But you can't tell that they are separate air chambers. We bought ours online at
http://www.thesleepbetterstore.com half the price of the national brands, but a longer trial period, just as good of a pump and mattress warranty. And the bottom line.....Feel like a firm mattress, got it. Feel like a softer mattress, there it is.
Good luck on your search.
