A simple profile, clean lines and meticulous attention to detail have made Ludwig Mies van der Rohe's 1930 Brno chair an icon of 20th-century design. The KnollStudio logo and the signature of Ludwig Mies van der Rohe are stamped into the base of each chair. A steel frame with no visible connections between seat and frame; seat and back constructed of durable hardwood; fully upholstered seat and back with variable density foam. Opaque, plastic, snap-in-place glides are included for optional insertion when used on hard floors. 'Comfort' thickness cushions.
