This chair doesn't fit me, I am 5'3". And I measured and compared to my current chair, it was a gamble buying a chair without first siting on it.  The highest setting is barely high enough to work comfortably at my desk and see computer.  The seat is too deep for me to sit back thus no back support so I need to buy a lumbar pillow.  Finally, the seat itself is very hard, so another cushion is needed. Only plus is that you can raise the arm rests.
If I could easily return it I would but it's already assembled.
