A theater chair, with essential lines and a side that recalls the shape of a tuning fork (“diapason” in Italian) or a “Y” as in its name, has the special feature of being compact in size. Elegance and compactness are even more highlighted when the tip-up seat is completely closed and perfectly adapts to the side without projecting, maintaining its elegant shape. It comes in finishes that allow infinite combinations, experimenting with fine wood finishes and embracing upholstery.
