Worth the money!
Assembly was straightforward and didn't take long. The wheels slide very smoothly across the floor. Sitting on this chair feels really comfortable. The back support and lumbar support are fantastic, it holds my back very well during long work hours. I'm very happy with this office chair.

comfortable
I've been using this chair for a few days now and I'm pretty happy with it. It feels solid and comfortable, and the back support is better than I expected. The padding has a nice amount of cushioning without feeling too soft, and the armrests are comfortable for working at my desk or gamin

Very comfortable chair
The chair is very comfortable and I really appreciate that the armrests flip up. It is wide and feels very sturdy and the adjustable lumbar support is nice. I purchased in-home assembly and the gentleman that came out from Angie was very pleasant, on-time and cleaned up after putting the chair together. I am very satisfied with my purchase
