Platner Stool was designed by Warren Platner for Knoll in 1966. The stool is made from multiple bent and welded pieces, which generate a marble effect unique to the Platner collection. The stool has a round seat made of molded fiberglass and foam. The chair is available in several colors, in velvet or other. The metal base is available in two variants, either in a matte metallic bronze color or plated with bright nickel. The base is also coated with a transparent protective lacquer. Platner Stool is Greenguard certified.

Platner Stool is a comfortable stool with a soft, elegant feel. It can easily complement any of the chairs in the same series from Knoll. The Platner collection also includes a chair, table, side table, dining table and coffee table.
