The simple structure of this chair designed by Mike Dye responds to the sitter’s requirements for support over a lifetime. With adjustable features for seat height, back angle, and head support, the functionality is put above the rest, making this chair unusual for a domestic piece of furniture. The chair’s base is constructed out of steel and the perforated spine is made from kiln-dried oak. Since people love their options, the cushion seat also come in a variety of colors and materials.
