Seating

UNIGAMMA
The stackable skid frame always looks light and reduced, with or without armrests. The armrests open to the front are reminiscent of the capital letter Gamma Γ from the Greek alphabet; they offer unrestricted freedom of movement and facilitate the handling. The surface of the comfortable plastic shell is glossy on the back and discreetly matt on the front. Whether at the table or in a row, its unobtrusive elegance makes UNIGAMMA a universally usable piece of seating furniture that also leaves nothing to be desired in terms of function thanks to the optional linking device.
