Ottoman. Bed. Lounge Chair. Armchair. If you're a habitual AT reader you probably know that we have a thing for multi-functional furniture. But Piero Lissoni's Trix for Kartell exceeds our usual standard, which requires that a piece be smart-looking and have a least two uses up its sleeve. Trix is the next generation Bingo Pouf. With just a few well-turned upgrades Lissoni elevated that cool idea to multi-functional furniture stardom. Wrapped in a luxe technical fabric and linked by a unique rotating rubber band system, these three expanded polyurethane cushions can be reconfigured from an ottoman into three other shapes. That's a total of four functions. (Four!) Priced to match its utility: $1,174, here.
