Overall this is a solid budget friendly office chair. Easy to put together comfortable with good lumbar support. I’m 6’4 and the headrest was not even close to where I need it to be even after extending the hight to it’s max. This was an easy fixe with an additional $20 purchase of a third party head rest cushion. Overall I am very happy with this purchase.
I picked this one over the Hyken for the larger size difference. Glad I did. But I wish the headrest wasn’t sitting on my upper back. I’m 5’10” and unless I’m leaning back does the headrest fit right. Upright it’s just too low. The lumbar moves randomly too. But overall great chair for the price. I can sit in this for 9hrs and more.
The chair is not very comfortable. There are large plastic lugs where the arms attach and the mesh stretches down so that your rear-end rests on them a little bit. After a few hours it is uncomfortable. The lumbar support is too aggressive in any position. I considered removing the lumbar support and grinding off the chair lugs but that seems like a lot of effort. The chair is getting returned. The chair seems to be of pretty good quality and assembly was easy. It's just not comfortable.
