Great chair for WFH. Overall extremely comfortable sturdy and lots of adjustments. I have to agree with other reviews mentioning the headrest though. I wish it was adjustable vertically because it tends to just slightly dig in to the top of my shoulders (I am 5' 11"). Other than that I can sit on this for 7-8 hours with no issues and would highly recommend it. The headrest can be removed if need be.
The chair is comfortable and I was excited about the headrest but since I'm 5'5 and have a long torso the headrest doesn't work for me. My shoulders actually come up higher then the bottom of the headrest so it pushes me forward if I sit up straight. If I slouch then it works great but that is not the intent of an ergonomic chair. Happy I can take off the headrest and deal because I'm not about to go back to Staples in the middle of a pandemic.
I searched for months to find an affordable chair that I felt would be comfortable and last a while. I did exhaustive research. I honestly think especially for the money you can not find a bet ergonomic mesh chair.
My wife has been working form home and she is the one that uses it. She loves the chair since the back pain has gone away after changing the one she was using.
