I've only had the chair for a couple of weeks but it is very comfortable partly because you can make so many adjustments. I highly recommend this chair! I use it 4 to 7 hours per day.
I really think this chair is great for it's price! It meets all the ergonomic standards for my At Home office. I found the adjustments to be confusing but overall once set up it has been very comfortable to use!
This chair is comfortable and well worth the price. The chair is easy to adjust to fit anyone. I'm sure there are higher quality chairs out there but I prefer to have good quality and upgrade every few years to take advantage of newer technology.
