The Spubble Chair a.k.a. Spubble is a reproduction of a mid-century classic. These chairs are made in the United States by skilled artisans and upholsterers, and are crafted from durable and authentic quality materials, designed to last for years and years. The Spubble Chair is made from ½ thick cast-acrylic, and features a chrome plated steel ring and suspension hook. This is not the Eero Aarnio Bubble Chair, but it is very much like it. Each chair comes with a chain and a mounting hook. We recommend installation be done by somebody with experience in General Construction.
