On a trip to Cape Town in 2013, the furniture-designing Texan twins Simon and Nikolai Haas, known professionally as the Haas Brothers, were browsing the stalls at a craft bazaar when they came across toy rhinos and baboons made by Monkeybiz, a collective of women from a local township called Khayelitsha. The brothers — who make weird, stoner-chic items such as ceramics that look like toxic coral or a furry daybed named for Anna Nicole Smith — collaborated with the Monkeybiz artisans, masters of beading, to produce creatures straight out of a Maurice Sendak story. The resulting collection, Afreaks, which includes a bench with an upright tail and an 8-foot-tall sculpture of a mushroom, will make its American debut at Design Miami in December and show again at Cooper Hewitt’s Design Triennial next year. And the women of Monkeybiz? They’ve started calling themselves the Haas Sisters.
