I have many back and legs problems.  This chair...the back moves with my back, its making it so I can sit at my desk without pain again! Twist and turn with support at any angle.  There is very little stitching or quilted padding on the seat that caused circulation issues for me behind my legs, smooth seat with no lumps and bumps is perfect for my circulation.  Padding is very nice on the seat.  This chair was the answer to my back support issues as some chairs are only supportive on the lower lumbar area, this one is supportive all the way up no matter how you move, it moves with you.  Love this chair!
