I was really excited when I purchased two sets for my new Tempurpedic mattress thinking they would fit like a glove. That unfortunately was not the case. The fitted sheet was left being really saggy and didn't fit at all. Now I'm stuck with two sets that don't fit and they were not cheap. I have never not been able to return unopened sheets before so I didn't even think to read the return policy beforehand. Super frustrating for sure. I don't recommend these sheets at all.
