These sheets are fabulous! They are soft, comfortable and fit my posturpedic perfectly.  The pillow cases have the envelope feature which is an extra bonus. The only downside is they wrinkle very easily. I thought they were wrinkle free, but once I pulled them from the dryer I realized there is no way I will get away without ironing these.  Aside from the wrinkle feature I love the feel, fit, and style of this sheet set.
