Initially, it was also quite comfortable to sit on, unfortunately, are the padding but after a very short useful life. The first chair I had complained after about 1 year (based on average use of 3 hours / day), because the padding was completely worn-out and we sat almost on the plastic. They told me a bit annoyed, but that I can not come back after 1 year with it because it was just normal in this price segment. After another year I had, as expected, the same problem (see photo) - In addition, the gas spring is now broken, causing the chair remains at its lowest level.
For the long-term use (+2 years) the chair is therefore unsuitable and not recommended. Anyone looking for a relatively cheap and nice office chair only briefly, perhaps here is the place to be.
