I have been sleeping on them for about 6 months and are the best pillows I have ever found. I purchased a real good zippered pillow protector to use with as you cannot wash them, and are a pricey investment that are hard to find. Target only carries the queen size. Excellent support, but you must get used to them. My son calls them "sand bags", and are heavy, very heavy. If you like a firm support pillow that stays in place, I highly recommend them. No more back aches, no more neck aches.
If you enjoy a pillow that is full and supports your head, this is the pillow for you! The buckwheat does not break down as fillers of other pillows do, including down. Read other reviews concerning the buckwheat filled pillows at other sites, investigate before purchasing! This is a pillow that will last many years!
