The seat and backrest are very comfy. The rollers and height adjuster work well. It was easy to assemble and looks nice. My only complaint is the armrests are hard plastic so they're not so comfortable to rest your elbows on. I wish they were padded. It's a good chair for home office setup overall.
For the price (I got it discounted and w/a coupon) is a decent chair if you're not at an 8hr desk job as it is very basic (arms don't move basic up and down function and some some give when leaning back). I move around a lot through-out the day and probably spend 4hrs on the chair a day. That seems to be my back's limit even with movement breaks.
