After a few months of complaining to one another "we seem to be sliding toward the center of the bed", we pulled the top cover today to find what appears to be water stains around the perimeter and large wet spots on the air bladders. When looking at the lateral supports, it's clear they are bending at the center which appears to be the cause of "sliding". I'm calling Select Comfort's customer service line tomorrow to hear what they have to say. My opinion is warranty has nothing to do with defective products, which these issues fall under. I'll post the results later in the week. read full review »
