Bought this about 3 month ago to replace the select comfort I bought for 4 times the money 2 years ago. I never slept on a memory foam mattress before, and I am very pleased with the feel. You don't really sink in like I thought you might, that's what has stopped me from buying a foam mattress before. I have problems with my hip joints aching half way through the night and I get that a lot less on this bed than I did on the select comfort (digital display on the pump controller burned up, and you have to buy a whole new pump to replace that, not willing to sink anymore money into this overpriced air mattress). Even if it lasts only 2 years, I'm still ahead on this deal!
