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.

Excellent chair for shorter users! The seat height and lumbar support fit perfectly, providing great comfort even after long hours of work. The PU leather looks sleek and is easy to clean. The wheels roll smoothly, and the 360° swivel works perfectly. Assembly was simple and quick. Great quality and amazing value for the price. Highly recommended!

Nice office chair!
Color: Dark
This is a nice office chair. All of the features work as stated. I would say the seat is slightly more firm than I prefer, but comfort is subjective. The pleather is soft and I like that the arm rests fold out of the way.
