Same here, owner from Belgium.
Bought the chair June 2019. It always felt on the low side, but my original desk was lower, so I didn't give it much thought.
I've since upgraded to a "Gaming desk", which is consideratly higher. This makes for a verry oncomfortable sitting position, and heavy strain on prolonged mouse usage.
I've started to investigate why this chair was just at 'kids' hight, and found this thread. Why there no recall or official statement is beond me...
My piston is sitting at 5mm from the floor.
