Bertoia Seat Pad is a seat pad that complements the Bertoia Side Chair and Bertoia Stool from Knoll. The pad provides a warmer and softer seat while protecting the surface of the chair from scratches and wear. The Bertoia Seat Pad is available in a choice of colors. The pad can be used both indoors and outdoors. For outdoor use, the pad should be stored away when not being used, to protect it from strong sun and rain.

Bertoia was mostly known as a sculptor and designed only one furniture collection. Although he did not work primarily as an interior designer, his paintings were highly acclaimed and are sold around the world today.
