My only complaint is not having bought this bed sooner. The bed is initially fairly stiff, however after 3-4 weeks it is breaking in very nicely. Actually I have a second complaint, and I hope that it finds tempurpedic employees. While I understand the importance of a mattress protector, it's moderately annoying to have one placed on top of the bed that moves around. You already have a cover that zips on the bed, why not make a protective cover that zips on to the bed? Even if it cost $250 I would buy it in a heart beat to avoid my current cover slipping on the bed every night.
