I purchased the chair after sitting in all the models available at my local Staples store... it was on sale for a great price and it felt pretty comfortable-however after having it shipped to my house and putting it together (also fairly simple and not too much time) I sat in the chair at my desk for several hours. Even though the chair is adjustable in many ways depending on your height (I'm 6 feet tall) you might find certain parts of the chair to be 'not adjustable" enough. This was the case for me with the arms on the chair. They just didn't go down far enough for me to comfortably rest my arms on them while sitting at the computer. The main "problem" however as I saw in other reviews was the "front edge" of the bottom seat pad - when you sit down on the mesh it "sinks" below the foam cushioning under your thighs and the "firm" ridge over time can cut off some circulation to your legs. I good chair and a great price but probably better for some people than others.
I bought this chair for my daughter since she is studying from home but I end up using the chair more than she has. I love it so much I plan to replace my budget gaming chair that I bought a prior year. The back support is great and I didn't realize how great the neck support is. I love the chair. My son has been begging me to get him one as he is sliding off the gaming chair and constantly complaining of back pains.
