This is a great chair. If you are tall it will be too small/short even if raised to the max height. I am 5'5" and it is a perfect fit for me. The seat is comfortable and the back can be in a fixed position or movable (similar to a rocker).
I have one of these in the office and it is so comfortable for all family members. When I needed a chair for another desk I looked at many others but in the end bought another one of these for the abvility to adjust it exactly the way you want it to be.
Per employee who received the chair.... I like it a lot so far. Very comfy. Adjustable lumbar is pretty cool. A lot of adjustments actually pretty versatile.
