Good but not great. Limited adjustment
Color: Cream
Chair looks great and is very comfortable and well made. I took stars off because a couple of issues that I can’t live with and will require me to buy another chair.
The chair does not rise high enough. Unlike other office chairs, I feel like I’m a little kid at the adult table(I’m 5’10” male).
The most annoying feature is the chair back angle isn’t adjustable so I’m always at a slight recline. I have to place a pillow behind me to look like I’m not falling asleep while on camera. Suprised there isn’t an adjustment for that.
I would have discovered all of this if I was able to try it out before hand but the mass positive rating don’t mention these issues.

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.
