This chair is wonderful! I am a seamstress and use it for sewing and for my long arm quilting.  It has adjustments on the lower foot ring height, seat height, backrest to go towards or away from you and the backrest can move with your body! The seat is cushioned well and contoured to fit your body. I am very pleased with my purchase and the great price from Wayfair. I would highly recommend this chair.  

Pros: Many adjustments for different tasks. Well cushioned. 
Cons: None that I know of
