The too low armrests have often been addressed, however, disturb me less (1.80 am and have a rather high upper body).
Furthermore, I can not say that something squeaks, creaks or is otherwise poorly finished.
However, the padding is too thin. I'm not particularly difficult (80kg) and more athletic ... prefer also always hard mattresses and harder seating.
But in this part I feel at least a few hours pain / the tailbone. Something was completely unknown to me. I work in an office and have as a pupil / student days almost exclusively when using PC verbrachtkeiner the chairs caused me similar problems.
As I said I have problems definitely only in this model (in the work, I often sit 8-10h and feel nothing). After this now after a few days of placing around (back etc) did not improve I write for the first time a really negative review on Amazon.
Tip: Better to buy a chair in a shop and test it out beforehand.
The 2nd star there for processing and simple assembly (ka why many here rummeckern).
