The back of the chair didn’t fit properly on the seat. Two people tried multiple times and the back moved about six inches when you took hold of it. One of the screws that came with it was stripped. I returned it. This would have a no star rating if that was possible.
The chair is very comfortable if you are sitting for long periods of time the only down side is the only way to adjust the seat it to have the back of the chair tipped back.
This chair has seat that is only moderately deep which means that the chair back better supports my back. However the front edge of the seat is quite uncomfortable due to the metal bar along the edge that presses against the back of the thigh and made my legs go numb. I had to add a 3 inch thick foam cushion before I was able to use this chair.
We purchased this chair for my mom to use at her desk. We assembled it with a screwdriver in about 30 min. Directions were simple and easy to follow. The chair has height adjustments for the seat and the arms as well as lumbar support that adjusts. It’s a very comfortable chair and a great value for the price. I would buy another one.
