The longer you sit on the chair, the more sensitive it reacts on slight movements of the sitting person and plays back some creaking sounds. Changes of pressure and tension become directly audible. Movements on the chair are proportionally translated into sound. It can be irritating as well as be fun to torture little herman.
Idee find ich gelungen, allein der Gedanke den ‘kleinen herman’ zu malträtieren bereitet mir entzücken. :]
