Italian company Kartell, founded by Giulio Castelli in 1949, creates versatile furniture and home accents that challenge traditional ideas of luxury by playing with color, material, and shape. Placing equal emphasis on function and form, the brand designs sleek products that are durable and weather- and shock-resistant. The award-winning pieces are often made in collaboration with famed architects and designers, such as Philippe Starck, Enzo Mari, and Tokujin Yoshioka.
