Design Classic – Influential and important design

Armchair 1957
- Designer: Eero Saarinen
- Material: fibreglass-reinforced plastic and lacquered aluminium and upholstery.
- Manufacturer: Knoll Associates, New York
The Tulip Armchair (model 150), Eero Saarinen’s last furniture design, was part of a five-year-long series of chairs, stools, and tables based on a single cast aluminium stem or pedestal. With the help of a research team from the Knoll firm led by Donald Petit, Saarinen faced the problem of treating the leg structurally and visually as part of the reinforced plastic moulded seat shell. This issue had plagued him since he and Charles Eames conducted their first experiments with moulded seat shells.
Biomorphic Design
The Tulip Armchair is shaped like a tulip and also a stemmed wineglass. One of Saarinen’s major concerns was clutter, which was addressed by this one-legged chair. He described his intentions to simplify and clarify the structure: “The undercarriage of chairs and tables in a typical interior makes an ugly, confusing, unrestful world. I wanted to clear up the slum of legs. I wanted to make the chair all one thing again.” Each piece of furniture in the Tulip series was created by Saarinen with a single pedestal leg, resulting in a coherent set of chairs, tables, and stools.
