It chair was easy to assemble and has been super comfortable so far. I get the lumbar support I need and I enjoy the headrest as well. Great purchase :).
After 5 months of teleworking due to the pandemic I finally did myself a favor and got this chair. It is super comfortable for long hours of work adjustable and quiet so far. I would've given it 5 stars except that the headrest does not adjust up and down but that's actually not a big deal.
For the most part it was easy to assemble (was having trouble attaching the wheels to the brace). Very comfortable to sit in and like that I can lean back.
It's a pretty sturdy chair overall but the mesh cushion does sink a lot (even when brand new). I'm 5'11 145lbs and the sinking makes my tailbone hurt after sitting for longer than around 30 minutes. If you're on the larger side it may be even more of a problem. I would definitely recommend either sitting on a pillow or extra cushion to provide extra comfort.
