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.
