This chair is really comfortable for long hours of sitting. It truly does support your back and your butt without aching. Also the installation was not hard at all.
Not very comfortable. The sides have a hard plastic rim that cuts into your hips when you sit. The rollers on the chair stick and makes it hard to move the chair when you are sitting on it and when your not sitting on it and just want to move it out of the way when you are cleaning.
Assembly was a breeze for my 13 year old son. It's adjustable just enough to be comfortable without being complicated. The head rest is the only part that isnt really adjustable to use comfortably. It can simply be removed though. It's comfirtable. After sitting in it several days in a row at work I had none of the pain or stiffness I was getting from other chair options. We'll see how it holds up over time but seems well made. My only other challenge is wrestling my 13 year old for who gets to use it.
