This is a great comfortable chair. I bought it to create a home office as I’m working from home during the coronavirus lockdown. It is shaped nicely to support my back arm rests are a good size height and leaning adjustments are nice and the headrest is a great added bonus support. Would definitely recommend.
Assembly is straightforward construction appears acceptable but not exceptional. I have only had it for a few weeks so no information on longevity. The mesh material is very rough to the touch which makes it uncomfortable if you have exposed skin (like wearing shorts). The major problem with this chair is it is it fits only a certain body type. At 6'4" the headrest landed solidly into the top of my shoulders at the highest possible setting. I've removed the headrest and the chair works OK as a mid-height chair with the top of the chair resting on the bottom inch of my shoulder blades. The arm rests are also rather narrow and brush my hips as I get in and out (at the maximum width setting). not enough to cause discomfort or difficulty but if I had more heft I would not fit. My wife is the opposite at barely over 5' she could not sit comfortably due to the depth of the seat and the lowest setting. I'm sure there is someone who this chair fits but it is not us.
I love this chair ... has helped greatly with my sore back/bum and the best part I didn’t have to pay $400-$1000 for a chair that is built for back issues!
I'm 6.1 and the headrest is way too low. It digs into my shoulder blades even on the highest setting. I went with this chair because of all the positive reviews; however I wish I would have searched through them to identify those written by tall people. I would say if you're 6.0 or taller - buy at your own risk as all those reviews complaining about the headrest causing discomfort are absolutely accurate.
The mesh pulled out from the base. I tried to repair it and found that the staples used in assembly had all been bent and were not holding i.e. clearly a manufacturing fault. FWIW I'm 175lb and use the chair 2-3 days / week so not an intense user. Pretty disappointing.
