We liked the one at Costco, but didn't want to haul it home. Went to Sleep Country, and found their version, which is a Serta, priced the same, and they deliver and haul out the old mattress/box springs, too. Great mattress, but really, really thick, so it can't be turned over, just rotated side to side. We made sure we bought the mattress cover that protects against ALL stains (we have a very elderly yorkie who sleeps there, too). It was $100, but absolutely guaranteed to protect the mattress or they will buy the next one. If you have any stains on the mattress and it becomes a warranty issue, stains void the warranty. We also have an extra thick mattress pad on it, so it can be washed often. LOVE the mattress, its been on our bed around a year, and we're very happy with it.
