The award-wining design practice MDA has created the RW chair, an adaptable design that responds to the sitter's changing requirements for support.

The chair's distinct, simple structure puts functionality first. Rather than incorporating complex mechanisms, this pared-down approach focuses on gradually moulding to it user's requirements over a lifetime, with adjustable seat height, back angle and head support. This range of features are very unusual for domestic furniture.

Evident in the design process is the practice's knowledge of working with a broad, considered palette of materials. The RW Chair comprises of a steel base with a cantilevered arm that supports a padded seat and can be adjusted using a simple screw mechanism.

The spine of the chair consists of two pieces of kiln-dried oak which are also independently adjustable, displaying subtle curves and shapes that were created using CNC technology. The perforations in the beautiful crafted wood animate the seat and provide fixtures to attach head and lumbar support pads. The base frame has for adjustable feet in the form of stainless steel discs.

The RW Chair is a limited edition. The cushion on the seat is changeable and is available is a range of colours and materials.

Originally designed for the domestic environment, the RW Chair has a good mass to volume ratio being very slim and linear in profile. The design responded to a brief from a private collector who could not find a chair that provided head and arm support which could be gradually adjusted to reflect the sitter's changing posture. The upright position of the chair creates a position ideal for reading, studying and contemplation.

Mike Dye, MDA Design, said: "It's been an exciting project to work on, stripping back the mechanics of adjustable seating to create a simple aesthetic that will age gracefully and help the sitter do the same. It's always refreshing when a private collector decides to put their hand in their pocket and ask for something new and different."
