The seat is very hard and uncomfortable. My back and bottom are hurting after spending about 8-9 hour days working with this chair. That is with standing for a few minutes every hour at least and stepping away for an hour lunch every day. I have been very disappointed by the comfort level of this chair.
For the price this is probably the best mesh chair one can buy. My only warning is to the tall folk out there: the headrest probably won't work well for you. I'm 6'3" and even when I adjust it to the highest setting my upper back is pushing into it too much. I'll probably just remove the headrest at some point
I found myself working from home (like many others) and the desk chair I had was not made for long hours. This chair is easy to assemble and has all the adjustments I need for the home desk. Super comfortable for 8 to 10 hours.
This is a very comfortable cool ergonically sound chair. It moves with me and adjusts for more chair sitting than I wish was needed. This is my second Hyken chair. I liked the red one in my office so well that I purchased a grey one for my home office. Assembly was easy for this 78 year old woman on both chairs. The included Allen wrench (for tightening screws) was the only tool needed. I like the way that it moves freely with my natural body movement rather than setting barriers and limits.
I think the price of my new chair was very good for the quality of the chair. The directions were easy to understand and the chair was very easy to assemble. I highly recommend this chair.
