The chair was designed by Arne Jacobsen in collaboration with Dr E Snorrason who gave advice on how to improve the lumbar support provided by the back of the chair. There is a sharper and more pronounced curve at the base of the back and the top of the back has a more generous width to support the shoulder blades.
The initial version made by Fritz Hansen was produced using a plywood faced with teak ... then popular and normally implying a more expensive piece of furniture.
With fairly straight sides to the seat and angled front corners rather than a smooth curve, the chair is more angular than the other shell chairs by Jacobsen - almost octagonal.
There was a version of the chair with a swivel frame with wheels so that it could be used as an office or desk chair.
height of seat: 42.5cm
smaller versions of the chair with seat heights of 36cm and 34cm were made for children.
