Overall is great product except the head rest. I am 6’4” tall and head rest is pretty much at fixed height in other words you can not adjust the height. I used the chair without the head rest.
The sales person indicated it was simple to put together. I didn’t believe him but I tried anyways and he was right. I did it by myself and was pleased with my accomplishments The chair is very comfortable and helps out my posture. If I had to have my cons would be the headrest. I wish it could Move if I didn’t want it at certain times
I originally bought one for my gf but liked it so much a few months later I wanted one too. The mesh keeps me cooler and the ergonomics helps support my lower back when I have to sit for long durations.
