Review on Ultimate Comfort Solution: BOD Support Adjustable Memory Foam Seat Cushion and Lumbar Support for Effective Pain Relief in Office Chair, Car, Truck – Ideal for Back, Tailbone, and Sciatica by Chris Sweeton

Really good quality seat cushion set. It's a little weird at first because your tailbone is kind of floating. After sitting on a pillow all day, I felt a lot more comfortable at the end of the day. It seems many people are unfaithful on this issue. The opening point goes where your tailbone is. Thus, it offers you relief without putting pressure on your spine while giving it a place to sit. Nice hardness and the good thing is that the cover is removable and washable. I need to buy more than one of these 2 for home, 2 for car and 1 for work. They guarantee very well that they support their product!
