I am a 5’9 165 lbs guy so pretty average in my opinion. So far I have it for a little over a month. Feels durable and the mesh allows for circulation. I can sit in it for long hours. Hopefully this will last me for many years.
It is wonderful for my back and posture with superb lumbar support but I found the chair to be very uncomfortable on my tush after sitting for a few hours and my butt ache. I will need to buy a gel cushion or return the chair.
Really like the form and fit of this chair has good adjustability for the price. I sit in this chair for 6+ hours a day at my home office with zero discomfort. Would buy again.
I have tried several office chairs and the Hyken is the best for my lower back that I have used. My son uses his for gaming for hours without any back issues. That is what sold me to get the chair. No regrets.
Same chair as they got me at work (after I brought a note from my chiropracter :) Only complaint is that for me the arms don't go down low enough or wide enough. I'm not a big person but I found my elbows were either banging on top or getting squished in even when sitting on a cushion. I found that there were an alternate set of holes on the bottom (but they didn't have the metal inserts - why not??). Using these instead made the arms lower and wider by about 3/4 inch (also moved them forward a bit but that didn't matter to me). Now Its great!
