Otto family

Design — Mario Ferrarini 2015 Otto interprets the theme of the stool, multifunctional element in domestic and community spaces, with a simplicity that expresses a strong personality. A single piece of tubular steel holds the round seat, wooden or padded, and acts as footrest. The gas-lift mechanism adapts the stool to many situations. It is available in black or white, or satin chrome.
