This is my second set of Tempurpedic sheets. The first set was the least expensive and have been great. We decided to splurge and get the top of the line-Egyptian Cotton. The fabric is wonderful, just what you would expect from Egyptian Cotton. The fit on these sheets is not good at all. The biggest problem is that one corner pops off, despite the elastic. This didn't happen with the least expensive pair. This happens several times a week. The other problem is that the sheets are somewhat loose, baggy, and wrinkly. This didn't happen with the cheaper pair. I definitely do NOT recommend these sheets. The fit is just not good.
