The chair came with all the parts nothing was missing or broken. It was very easy to put together 20 minutes tops and that is me really taking my time. I had my younger sons help otherwise it would have been quicker. Has 3 components for seat height tilt and angle of seat. If this had a mesh seat then I would give a 5. Great chair for the money.
Solid chair with plenty of options to customize fit and it provides great support. I truly appreciate the curves of the design both in the “cupping” of the armrest and on all edges. Rolls easily
