Whimsical and versatile. The Colonna Stool from Kartell is a stylishly modern product with a playful side that is perfectly symmetrical and proportioned. This product’s flexibility lets you use it as either a stool, as the name suggests, or a side table to place a book or a lamp in a bedroom or living room. It’s made out of a thermoplastic technopolymer, which is then formed into an elegant shape that provides thoughtful urban appeal to your space.
