I'm 6' tall and the headrest hits me in the shoulders. The seat is also to too short to be comfortable for me. It might be fine for someone shorter. The seat and back are very abrasive but they might smooth some with use.
Overall a great chair. I just wish it had a bit more fore-aft adjustability to the head/neck rest. For me it's too far forward to be comfortable. In fact I simply took it off as it doesn't seem to add much functional vaue and for me it was a bit uncomfortable.
The mesh seat and back are the only good points of the chair. It is not very comfortable and the head rest is not configured correctly. At least the headrest can be removed. The seat bottom is too short. Seems like the chair is made for people 5'-6" or smaller.
Purchased after trying demo in store. Seemed very comfortable. After using the unit for a few days (did not open it for a while) I found that there was a lot of pressure on my thighs. After an hour of so they began to ache. I feel that the arc of the seat is too extreme. I like the quality of the product and the adjustments provided in the design. However it is not the most comfortable chair for me. I liked my old worn out pretend leather chair much better (May it rest in peaces).
I bought this seat because it was mesh. That part is great. It's very comfortable and supportive. The only flaw in the design is the headrest. While the ability to tilt the headrest is nice it does not adjust up and down by more than an inch or so and consequently hits me in the shoulder. If I adjust the headrest back to not hit me in the shoulder then I do not find the headrest functional because it is positioned looking at the ceiling.
