This executive chair, he was bought in 2009 for around 100 euros, continues to this day without any significant mechanical problems well. Of course, the leather used by the cheapest quality and therefore decomposes on the armrests and turns on the head rest and the seat easily. For a product with this price may be not the expected, after all, the executive chair is in almost daily use for several years.
Finally, I give this office chair by my long-time use 4 out of 5 stars because everything is still working as the day and the only maintenance is tightening some screws. The small deduction in the vote there because four screws hidden within the seat cushion part and I had to not only remove the leather sleeve for tightening these screws, but had to contend with the bonded foam.
I saw that dissolved in other chairs in this class better, therefore, not quite perfect score.
