If you need extra back support choose another chair
This is a nice inexpensive chair. The cushioning is ample. At 170lbs I can feel some give in the seat, so I wouldn't recommend it for anyone over 200lbs or someone who must move constantly. The fabric is very nice and not abrasive at all. The casters roll relatively smoothly but aren't meant for shifting from one desk to another. Swivel is smooth and easy. My biggest issue is that the chair is too deep to provide back support for long use. The back is slightly inclined requiring the user to self support during any desk tasks. I purchased these as a stylish accent in my home with dual purpose as homework task chairs for my kids. I see no issue with that use as homework is typically completed within 2 hours. The lowest height is a bit uncomfortable for a full grown person but would be perfect for a kid, while the highest adjustable height is perfect for the standard 30 desk height. I am looking forward to many years of use and visual enjoyment from these chairs.
