About 6 months ago I bought this chair for my office and really liked it. I liked it so much that I bought a second one for my home office. Extremely comfortable. Very easy to put together. All screws are individually marked. I'm 185lbs and use the chair about 5-6 hours per day each. So I expect it should last. Highly Recommend.
For my personal use 2-3 hrs per day I find this particular chair to be comfortable sturdy and an easy to assemble chair. Cushion & back support could be a bit firmer and height adjustment range should be higher. Overall an excellent value from high priced alternatives.
