I purchased this chair for my job and so far it is very comfortable. I spend about 6-8 hours a day sitting and this has been one of the most comfortable chairs I have had in all my 4o+ years of doing office work. We ordered 2 more one for the general manager and one for the owner because they liked the way mine felt when they sat in it.
My husband and I bought this chair since we started working from home. When we first tried it at the store it was comfortable and worked for when we were not working a lot of hours. Over time we have seen that the cushion for your bottom flattens and the chair starts to move from side to side. Since I am working full time from home it's not as comfortable as it used to be. I've had to place a pillow to help give some extra cushion. We also have had to tighten the chair at the bottom to help stop the side to side movement. For the price I thought we were going to get more cushion. If you're not spending so many hours at your desk it can work for you. However if you're working full hours at your desk - you may want to find something more comfortable.
Using this on my gaming computer and it's pretty nice. The arms move out of the way so I can play but sometimes I just watch TV and lean back on the chair. It was very easy to put together and seems durable. I weight around 175lb and it feels sturdy enough for me. I would buy it again.
