I just received the chair and I'm already in love. It is super comfortable and it is extremely sturdy. I did a lot of research before deciding on this chair. I made the right choice! I spend most of my time at my computer so I need a comfortable chair. I was in a car accident a while ago and my old chair was uncomfortable which caused me additional and unnecessary back pain. It does tilt, by the way. This chair feels great and fits me like a glove!  I am very happy with this purchase.
