I purchased a top of the line Pillowtop Queen Mattress in April of 2010. It's very comfortable except for there's a bump at the foot of it where the foam had broken away.
It was purchased at Best Mattress. When I went and told them what had happened the saleman said that he would talk to the Serta Representative to see what can be done, but didn't think that they wouldn't warranty it since the mattress had been moved. Sure enough that's what they said.
But they did offer to give me a discount on a new one. Like I would buy another Serta.
