Designed primarily as a sculptural work of art, the Sphere can double as extra seating when entertaining. Its solid round shape radiates a quiet strength, while the off-center cutout near its base lets light and environment create spatial shadows. Though it gives the illusion of appearing perfectly round, the Sphere has a flat base to keep it from rolling. Constructed of solid O.S.B. (Oriented Strand Board), which is a mix of fast-growth hardwoods such as Maple, Poplar, Birch, and Pine. Fast-growth forests are harvested every few years and replanted. This reduces impact on old growth forests. Made in the USA.
