I was not happy with my TEMPUR-Could Topper at first. It arrived, well let's say imperfect. The topper was flat around the edges, but more importantly, it was an inch too short on all sides. Instructions said it would expand, however that was doubtful. I've had several toppers from other companies and none were like this. Needless to say I was disappointed. HOWEVER - Tempurpedic quickly sent me a replacement topper - which was near perfect and so, so comfortable. I love it.
