Named after its unique adjustable backrest, SIA, meaning movement, is a lightweight timber chair that is slender in design yet uncompromising in comfort.

Shaped from solid natural timber, the curved seat and articulated back is contrasted by a minimal steel frame that supports the sculptural timber elements and allows for a convenient stackable design.

While originally conceived for the dining room, the SIA chair is perfect for both commercial and residential applications.


Seat and Back: Natural Oak, Ash, Black Stained Ash or Walnut.

Upholstery: Mokum Strata linen, Kvadrat colline 228, Leather vero nutmeg (also available in various fabrics and leathers)

Frame: Black or White powder coated mild steel.

Also available in an unupholstered seat chair and bar stool.


410mmW x 510mmD x 775mmH, 450mmSH
