Several things I don't love about this chair in order of annoyance: 1) My hips sink down into the mesh and kinda get squeezed between the frame...not too noticeable if only sitting for a few minutes but been working from home with COVID so not happening for me. 2) Wearing shorts with the mesh is not very comfortable. 3) the bottom of the head rest support hits the top of my shoulders. I do like the ergonomics of this chair as my back stopped bothering me as much when I started sitting in this chair but the negatives totally outweigh it. I have already bought another chair & was going to return this one but my wife said she would use it in her office (a.k.a. our bedroom). Keep in mind I am 6'1" 240lbs and she's 5'1" and 100+ lbs lighter than me so we'll see if these things bother her as well (minus the headrest which she has indicated she has no interest in keeping).
This chair is a very comfortable. The only part that I would like to change is to raise the headrest up another couple of inches. I am 6 foot and the head rest sits on my neck but is still nice to lean back and relax while on the computer.
This chair is really great. Working from home 8 hours a day due to social distancing guidelines I need a chair similar to those really expensive Herman mesh chairs. This I feel is almost better in ways to thst chair. The lumbar support is right where I need it and the chair can rock and can lock in at any reclined angle if you want. There is a tension knob to increase or decrease the tension an adjustable head rest. Perfect for me at 5 ft 7. This can be removed if you want. Only complaint I have with chair is even though the arm rest can move up and down the armrest themselves are very hard. Softer arm rest would of made this a five star chair. Only other issue I had was I ordered black but got red instead. The box states black but it was red. I was also bummed that the black chairs are selling for like $160 a week after I bought when I paid about $230 for mine. My friend at work got the black one at the lower price. But still is a great chair a d a grew at value for a chair that is replacing one that is 5 times the costs of this one. SI did not return red because I didn't want to the hassel bit for those considering the red the red is not as red as the picture makes it on the site. It's a darker red mixed with the black mesh soit is a little muted. I'm ok with it but still was not the color I ordered.
