Bought 2 Sealy Atwater queen size Mattresses from Costco Canada. One Mattress developed *** on one side. Flipped over same problem. The other mattress squeaks very badly. I have called Sealy Customer Service, left several messages over the course of 2 Months. I reached The Receptionist 2 times, and assured me that I would get a call back. I asked to speak to someone in charge and was told there's no one to talk to me. This Mattress has a 10 Year warranty.I had not read the bad and low reviews ( 2.9) User's recommendation: do not buy any Sealy products, not a good value for the money.
