It's a basic office chair for short term use. It's not an overly comfortable chair Sitting in this chair all day is tiring. It leans slightly forward to qualify as back support but I find that uncomfortable. The arm height is fixed. You can only control up and down for the seat. For the money I guess you can't expect more. I'll use it at a low volume station while continuing to look for a good value in an office chair with a better design that will be comfortable all day long.
This chair is exactly what I needed to be comfortable at my desk. I also appreciated the folks at Staples putting it together for me and taking it out to my car!
