Nice chair rather easy to put together. I have only had it a week or so. Thus still trying to get used to the mesh 'seat' part. The back and headrest feels fine. But the seat part to me takes a bit getting used to. Sometimes I feel as if I am 'falling' off the seat. Other times as if my buttocks is not on the seat properly. Again I feel I just need to get used to the mesh since it moves to fit your body versus a solid piece of foam etcetera.
Due to Covid 19 I will be working from home indefinitely with no ETA for return to office. My old office chair was not conducive to supporting my back legs etc.. for 8 to 10 hours a day. This chair is what the doctor ordered.
My fiance whom this chair is for is 5'2" and this chair is perfect for her she can sit in it for an extended period of time without cramping or sweating and the headrest is positioned well for her. I on the other hand am 6'2" tall and the headrest is just barely above my shoulders and is not comfortable for me at all. Still give 4 starts though ss you do not need to install the headrest for the chair to function.
