The Osso Stool’s gently concave seat perches on elegant round legs with footrests. Ronan and Erwan Bouroullec say the quality and "sensuality of the wood" makes the object; this object adds subtle elegance to any room it sits in. A high-technology, solar-powered system assembles the chemical-treatment free wood panels, legs, and footrests, creating strength to match their beauty. The Osso Stool is available in varying heights and in finishes including black, blue, green, dark grey, pink, white, natural ash, and natural oak.
