Other than being a good chair it has a few fallouts. The mesh of the seat and head rest are loose especially the seat is not firm enough for great comfort. The cushion (front part of the seat) and the hallow part of the seat is not flushed there is a dent because the mesh is not tight enough.
Overall I like the chair the seat height adjustment and the back tension adjustment have a great range. My only issue is I wish the arm rests lowered more. The lowest height setting is too high for me so it causes me to scrunch up my shoulders. I am 5'6" and average build for reference. I'm not returning the chair because I don't want to deal with the hassle of taking it back after I already assembled it. Also FYI the caster wheels will scratch hardwood floors so you need to put something down to protect them. Staples had really fast delivery and the chair was easy to assemble.
I love this chair. Love it. I had one for about a year and then the lift cylinder gave out and it kept dropping down so I had to relift the seat 5-25 times every work day. I tried to find a replacement cylinder but because of the size (it's way smaller than the standard) I couldn't. So I bit the bullet and shelled out another $200+ for a replacement. I've had this one less than 4 months and here we go again. I'm nowhere NEAR the weight limit for the chair but I've had to raise the seat up today alone 14 times and counting.
This chair is very supportive and extremely comfortable for long work days. The mesh back and seat support keep you cool and comfortable and the headrest is a nice feature. It is the perfect chair for someone who is of a slim to medium body type.
Good quality chair - same as what was observed / tested / chosen on the Staples showroom floor. The seat and back allow good flex which for me helps manage / mitigate pain in my lower back and tailbone regions. Headrest is attached in place but can be tilted it's location is comfortable if I want to lean my head all the way back / rest my head and neck.
