Bought the chair for my wife who works from home. She had a spinal fusion 2 years ago and struggles with any type of sitting for long periods. This chairs lumbar support made a huge difference for her!
Arm rest minimum height is slightly too high causing shoulders to shrug a bit. Also too wide. Seat depth is too deep making lumbar support difficult to use. Wearing shorts not recommended as the material is rough and causes imprints on skin. The backrest angle isn't adjustable and the default position leans back too much. It makes the headrest unusable unless I lean into it. Assembly took a little over an hour and was straightforward but the back rest was a little difficult to attach and required help. Overall I wouldn't recommend based on all of the aspects covered.
It serves the purpose I used it for like 10 hours a day and it is an ok chair. I usually sit on one leg folder which I can't do on this as I am afraid to break the mesh.
I love this chair it's very comfortable and for my height and weight it feels just right. The lumbar support is a lifesaver as I am not suffering from any backaches. Anyways I would recommend this chair to anyone that works long hours behind a computer.
