Designed to fit varying ergonomic needs


Inspired to create a design that fits varying ergonomic needs, the idea of Trioo was to create “one” chair but with three different characters. One frame, one seat and three different backs give the chair three different functions and expressions. All three variants provide support to the body, whether it is the back, arms or elbow, at rest or in motion, and with its rounded shapes without any sharp edges, users can sit comfortably composed in the chair. Trioo has been designed to fit any environment, be it at home or the office, café or university campus.



Johannes Foersom & Peter Hiort-Lorenzen were inspired by Lammhults´ design philosophy when creating Trioo – working to make a natural and uncomplicated form. They also wanted to exhibit the warmth and softness of wood as a material, using a transparent finish on the design that allows the structure of the material to shine through. The chair seat and back are available in moulded veneer in natural ash or oak and in stained ash. Stains available are white, graphite, black and mole (beige/grey). The seat is also available upholstered in fabric or leather. The steel frame comes either powder coated or chromium plated.

Some pictures may show products in a non-standard size, powder coat or fabric which can attract additional costs.
