Beautiful chair! Assembles easily and extremely comfortable. Has height adjustments but no lumbar adjustments which is ok. The lumbar support for me is perfect. I had pain from an improper home office chair I was using for a couple months. Within two days pain was gone. Only reason it is 4 stars vs 5 is there is a slight lump formation in the seat after sitting on it for a week. It my be the 20 lbs my ss has gained being in quarantine so take that feedback or leave it. Great chair!
