I had bought the same chair for myself on 23-09-2020 and I was so satisfied that I bought the same chair (the order for which I am doing the review) for my father since he also has issues with his back.

Let's finish with the one negative of the chair. It is expensive. For a chair, as I think of chairs, it is extremely expensive. In my first purchase, it cost me 399 euros and in the second, it cost 420. That being said, it remains good value for its price (as I explain below).

One observation is that as a chair, it is quite low (compared to the others).

Due to excessive weight, the chairs I had over the last decade started to break down very early. Within the first weeks, you lose how easily the chair moves (mainly from the wheels). In the first months, the mechanism that lifts the chair breaks, and over time the "foam" in the seat has compressed and you can feel the metal parts of the chair in your butt, the back doesn't lean back anymore, etc. - until the breakages start. I have had this chair (from my first purchase) for 1 year now and it is literally like new. Nothing malfunctions, the movement is as it was when I first got it and my main fear before buying it (that since the seat is made of mesh only, it would tear from the weight) never happened.

The other positives can also be seen on its page (how customizable it is, etc.), I won't reiterate them here, but they all hold true and I literally have the most comfortable chair I have ever sat in. So much so, that I bought it again for my father.
