I wish that the arm rests swiveled. The way they are it is uncomfortable to use them when typing. Otherwise I love the chair and the support it gives my poor old back.
The chair is a good fit for me. It's comfortable and supports my back. I like multiple adjustments for the height back and seat. The only thing I didn't like was the arms do not rotate. But I knew that before I bought it.
Very easy for one person to assemble. Lots of adjustments up down seat and back have separate tilt features (or you can freeze tilt). Back adjusts up and down so you can get the lumbar support in the proper position. Arms have set up/down adjustments but no swivel from side to side. (You do not have to put the arms on if you don't want them.) Seat cushion is not as soft as I would like but it provides good support. Seat is also 'warmer' than an open mesh seat (but I have found that those frequently put pressure on the back of my legs where the frame is.) I actually find this chair more comfortable than my much more expensive 'ergonomic' chair in my work office! Purchased for WFH Home office. I am very pleased with my purchase. I only wish I'd bought it earlier!
