Purchased Queen size mattress and foundation on 12/17/08. The bed became saggy and it started popping in different places. Called and they sent a tech out on 2/7/2009. Was told by tech that someone would contact me in 24 hours and it took 4 days and I had to call. They replaced both mattress and foundation on 2/18/2009. Called them back on 3/2/2009 with same problem as before. Tech came out on 3/9/2009 and said some one would call me in 24 hours. I had to call 4 days later only to be told that they would only be able to replace with same mattress. If I have the same problem with my 3rd mattress I will call back and they will send a tech and replace the mattress again. To me there is a manufacturing problem with my mattress. I want a free up grade so I can get a good nights sleep!
