For the price you can't ask for much more. Offers so good lumbar support and the chair is sturdy and durable. Also the assembly instructions are easy to understand and straightforward.
I have been working from home for the past 6 months. I had a desk chair that I had previously bought with looks and decoration in mind rather than functionality. I had to kick it to the curb when it started hurting my back to sit in it too long as I work 12 hours a day from my desk. I did my research on what type of chair to buy and I figured this was my best bet. It arrived quickly and the first couple of months I LOVED it. It has cut down on the pain in my back and it is just overall a comfortable chair. My one issue with it is that the mesh after a while isn't as tight as it is when you first get the chair causing it to not be as ergonomic. It still is comfortable but I wish I got some more use out of it before it started to go soft. I will keep it until I cant but for the price (when it wasn't on sale) I expected it to last a little longer.
This is by far the most comfortable and adjustable office chair I have used. I love the adjustable head rest and arm rests. The FlexFit mesh is great as it provides good support and is comfortable.
