Filo incorporates intelligent design like no other high density stack chair. Providing unsurpassed strength while eliminating the need for a front cross beam, allowing for leg under comfort, it will withstand the rigors of high-use environments. Options include stacking arm chair, stacking stool height, stacking stool height with arms and ganging clips. Designed by Alberto Basaglia and Natalia Rota Nodari the Filo features a renewable seat and back. Tired of the color you have? Simply replace the seat and back with our toolless replacement system. Although nearly impossible to remove without proper instructions the seats and backs can be exchanged once you know the secret removal process.
