The chair is okay. You can see that it has been made with quality materials and it does have nice features but, for the price I paid, I am a little underwhelmed by it.
Firstly, the arm rests are a real disappointment. For starters, they are far too short . They should be longer so that they support your whole arm but they don't. Also, the design isn't particularly very good. Although they are designed to slide back, (which is a nice feature), if the chair backrest is in the position where it leans forwards, it prevents at least one of the arms on my chair from sliding fully backwards. Also, the material the arm rests are made from aren't very comfortable. Why can't they add a bit of foam padding to them for comfort? You have to rest your arms against a hard, unyielding, PU plastic surface which isn't the most comfortable of experiences.
Another disappointment is the tilt feature. The chair doesn't recline very far back. You'd want it to recline at least a little further than it does to allow relaxation breaks between work.
Finally, I have had issues with the chair. When it arrived, the metal components on the underside of the chair were covered with grease and oil which has leaked off and caused cosmetic staining to the underside of the chair. Also, when testing the seat base tilt adjustment for the first time by just following the instructions in the booklet that comes with the chair, the chair made an horrendous cracking/snapping sound, so I am not sure if anything has broken.
So, it's a 3/5 for me. While better than most cheaper alternatives on the market, I think the overall design could be vastly improved.

I've just received the chair and it feels very well-built. The seat cushion conforms to my hips, and the strong load capacity handles daily use with ease. The adjustable seat and backrest meet all my needs. It was also the quickest chair I've ever assembled!

This chair is impressively supportive. It even fits my father, who is a bit larger, perfectly. The seat depth is adjustable and wide enough for a comfortable hip position. The adjustable seat angle improves posture and makes it even more comfortable for extended periods.
