I purchased two My Pillows many years ago from a store, it was time to replace. After checking the tags on the old pillows, there was nothing to denote the type, so I ordered two new pillows, one with extra loft. It took three weeks to receive the pillows with instructions to place in the dryer for 15 minutes. It does not instruct heat value. After 20 minutes, pillows were removed and placed on the bed. Upon lying down, my head went almost to the mattress. Next day, an additional 30 minutes in the dryer did not change the outcome. I contacted My Pillow, I can exchange them for an upgrade pillow for more money. I looked at the web site again to make sure I hadn't missed a description--I had not. NEVER AGAIN. Either the material used to stuff is inferior to before or not enough is placed in the pillows. Completely unacceptable merchandise. I went to a store today and purchased new pillows from a reputable company.
