Very happy with my chair! I work from home and was in the market for a new chair. I was a little nervous buying one without sitting it in first but I love it. I am 5'11 and it fits me perfectly. Even if you are not 5'11" - it's so adjustable! I love the mesh, head rest, adjustable arms and the wheels. I am easily float to my two different desks with a push with my toe. But the best is the lumbar support and general fit - great purchase. Fast shipping and easy to assemble.
