I use this product to do my school work, and that requires me to sit down for hours at a time. The chair is comfortable throughout this process. The only thing I don't like about this chair is that the lever for height adjustment is a little tricky to install properly.
My other chair had fabric and the dog hair was really attracted to it. This chair is great because it is leather..no dog hair. Very happy with my purchase.
Use it everyday and love it. Comfortable with better back support than my last one. Only problem I've had with it is the locking device to keep the chair from being able to lean back comes out and you have to re lock it.
