Input: Seems functional, but kind of hard. Maybe it will break in. I do notice a difference in posture so it basically works. 2 stars for flimsy zipper which, upon arrival was jammed in the halfway open position and not possible to close. I would return but I need it for my back and have doubts it would last anyway.
