The lateral sides and upper side of the seat are made of veneered beech plywood.‎ The underside is veneered in ash wood.‎ The backrest is made of solid ash wood.‎ Varnished in natural ash or lacquered black.‎ Bottom structure in tubular steel and pieces in cast aluminium with a powder coating in white or black.‎The B Table was the first in the Extrusions collection and an aesthetic which is the product of a combination of industrial and manual processes.‎ The result is a “highly crafted” piece which surprises with its solidity and lightness.‎ To complement it, Konstantin Grcic has now designed the B chair, a wooden chair with pieces of aluminium in its structure.‎ The legs are X-shaped and the seat folds, which allows for horizontal stacking and pays tribute to the name of the collection.‎ A detail of genius.‎ The decorative touch is concealed beneath the seat, which is offered in a varied and attractive range of colours.‎ Sides and back in solid natural ash, varnished.‎
