HORRIBLE! I purchased a set of sheets (king size) and came to find out they don't fit my tempurpedic mattress! After several calls to customer services, I had to figure out that those sheets did not fit my mattress due to the depth. My mattress depth is 12 inches (it does not have a pillow top) therefore, the sheets fit HUGE! No one could figure this out- very disappointing that this company does not offer sheets for all of their mattresses! Will never buy a tempurpedic again!
