Overall great chair for the price. Attractive for home office, nice materials, nice functionality, easy to assemble. Four stars because one reason I bought this chair was for the tilt function and that part works some but does not work well - dial is very hard to turn. While back is nice, it does not have ergonomic type back support but is comfortable enough that I'll just use a small lumbar cushion for longer work sessions. Given what you get for the price, I like it enough to purchase a second for the other desk in our home office.
