Comfortable chair
Color: Black, Color: Black
I wanted an all black out chair to match my cabinets and this chair fits my needs. It was easy to install took me about 20mins or so. Quality is great, the base is made out of metal hence very solid, it came with the polyurethane wheels, rolling on the hardwood floor is very smooth. Seat and arm rest have thick foam paddings makes it very comfortable to seat on and lean back. Adjustable recline tension and height adjustment. Great chair.

GOOD
Color: Black
The chair was more comfortable than I expected for the price. The back support feels good and the seat does not feel hard after working for several hours. I liked that the wheels roll smoothly and the assembly was pretty simple. The design also makes the office look more modern. So far it feels stable and durable.

Sitting on a very comfortable leather chair
Color: Black, Color: Black
I have been using this chair for a few days. First of all, the installation is very simple and convenient. You can learn it just by looking at the drawings. It takes about 20 minutes to install. The chair is very comfortable to sit on. Its support and comfort are beyond expectations. It can relieve the fatigue of the waist and you won't feel very tired when sitting. The leather material is also good. It can be rotated, moved up and down, and can be moved. The armrests can also be moved up and down. This price is worth it. Overall, I'm very satisfied and comfortable.

Very comfortable chair!
Color: Black
This office chair is a great addition to my bedroom. It offers really nice comfort because of its thick and cushioned back which helps make long hours at a desk much more enjoyable. The adjustable height is really nice as it makes this chair extremely versatile. The armrests are sturdy and positioned well for typing or resting your arms. They also move back if you don’t like them.  The assembly was straightforward and didn’t take long as the instructions were clear and easy to follow. The wheels roll really nice and don’t get stuck. This chair is really comfortable and nice.
