This chair is really comfy and the persistent back pain I experienced with my previous chair is greatly lessened thanks to the lumbar support and head rest. It’s easy to assemble. I love it!
It seems pretty comfortable so far. However the padding on the chair arms have already lost their shape and flattened the padding is gone. I do expect problems in the near future with the seat losing it's hydraulic pressure because at times I find the seat lower than where I adjusted it to.
