Very nice chair for the money. Have not had any back/shoulder pain since receiving the chair. My husband said it was the easiest thing he has put together and that all parts were clearly marked and color coordinated along with clearly articulated directions.
Love this chair. So comfortable and offers great back support which was important to me as I have been working from home and sit at the computer for hours at a time. It was easy to put together(20 minutes). The only feature that would be a plus would be the ability to recline.
