Pillow Ease, Coccyx Seat Cushion.  This is a wonderful product, you never know how badly you sit until you use this.  I have had great posture all afternoon.  It is extremely comfortable, and very well padded.  This will ease some of my lower back pain while I am sitting.  It has two covers, gray and a very soft black.  Zippers for changing the cover, very easy.  You can take this anywhere, car rides, plane, concerts, ball games, anywhere your going to be sitting for a length of time.  If anyone has back problems I would recommend purchasing this item, you won't be disappointed.   Thank you for allowing me to try your product  I recommend this product.  Disclosure: I received this product at a discount in exchange for my honest review.
