Dorso is an armchair designed by GamFratesi for Hay. Available in various finishes for the base and a wide range of fabrics for the upholstery. Dorso is inspired by the changing shapes and curves of a human body in motion, combining a rounded exterior with a 360-degree swivel base, a rather rare feature for a four-legged armchair; so GamFratesi creates an armchair capable of offering great comfort without neglecting functionality. High level of comfort, functionality, all seasoned with rather compact dimensions, make Dorso able to fit perfectly into many different contexts, from conference rooms to lounge ones, from waiting rooms in public environments to private residential spaces. Materials:Molded polyurethane (PU) foam shell with internal steel frame.Seat cushion in polyurethane foam (PU) with padding and non-slip fabric on the bottom.
