I bought a set of these sheets 2 years ago in white and love them. I decided to get another set in the blue color, which is lovely. The seams are all wrong and the hems are bunched up and unsightly, the pillowcases have a diagonal seam (rather than a straight side seam), so your face is on the seam no matter which side of the pillow is up. I returned those sheets, thinking they were sewn on a bad day, and bought another set directly from Tempurpedic. They are defective in exactly the same way. What has happened to quality control? I'm very disappointed. These sheets were expensive. I don't recommend them.
