Chair is comfortable and fine. The assembly specifically the headrest was problematic. The screws were not aligned correctly with the holes. I had to go to my workshop and drag out a vise and they force fit the parts. Someone without the strength and tools might find this difficult to put together.
I use it daily I'm 6'3 and it fits all my needs perfectly good headrest good lumbar support was easy to put together. It was an ideal product at an ideal price.
