Kartell La Bohème Stools. Designed by Philippe Starck for Kartell each stool is made from smooth batch-dyed transparent polycarbonate. Drawing inspiration from the curved forms of vases, these exquisite stools are durable, functional seats for indoor and outdoor use that have the appearance of two delicate vase designs. La Bohème 2 features a low base and flared top. La Bohème 3 has an amphora-style shape.
