I bought this chair because I worked around 10 hours a day and having a chair with a good support is important. I started using it today and so far it feels good. I cannot give the 5 stars yet as i am just using the chair. one of the characteristics that made me bought it was the fact that you can adjust the high (if you are a short person this is key) and also you can pull up the arms. Also putting the pieces together was easy and you can follow the instructions and you will have your chair ready in less than half an hour. Another good point is that i bought the chair in a sale event (-50$ from the original price) and it was shipped to my home without additional cost.
Extremely easy to assemble and very comfortable. I bought to replace an old chair and use this for my WFH status. Seemed like a good value for the money. This is our second of these. Purchased one earlier for my wife's desk about a month ago. She loves it!
