Sturdy, heavy duty

I wished there was a wheel lock, because it just rolls randomly when I’m not sitting in the chair. Other than that, it is sturdy and heavy duty and very comfortable. I like the neck and back brace when I’m working. The adjustable arm rest is a plus as well. Good if you weigh over 250 lbs.

Comfortable and Excellent Value

I've been using this chair every day for both work and general computer use, and I'm very happy with it. The mesh back keeps me cool during long sessions, and the adjustable lumbar support provides good lower-back support without feeling too aggressive. The seat cushion is comfortable, even after several hours of sitting, and the armrests are positioned well for typing and everyday use. Assembly was straightforward, and the chair feels sturdy and well built for the price. If you're looking for an ergonomic office chair without spending a fortune, I think this is an excellent value. It's comfortable, supportive, and has made working at my desk much more enjoyable. I would definitely recommend it.

Great for a petite person

Basic chair but perfect for a petite person. I am 5' 1" and had the most difficult time finding a chair with small enough seat. This one works!
