The frame of the Artek Armchair 42, is made from laminated birch shaped to produce a cantilevered chair; the seat and back are created from one piece of form-pressed plywood. The fluidity of the design creates a soft, comfortable place to sit. The result is an armchair without straight lines, an armchair of exceptional aesthetic appeal. Since wood changes over time, the armrests are formed from a single piece that is then split in half, ensuring that as the chair ages, it remains perfectly balanced. Artek Armchair 42 was designed by Alvar Aalto for the Paimio Sanatorium in 1932.
