Just like the changing situations of everyday life situations, "Mingle" evolves with the situations in which it is used, whether in our private spaces, at home or in public places such as conference rooms, museums, etc. The image of the fixed stool is reinterpreted to make it flexible.The user can manipulate the seat as he or she wishes, in a very simple way, thanks to a system of pivots and axes that allows the stool to be a bench.
