This very rare SZ15 lounge chair, designed by Kwok Hoi Chan for Spectrum in the 1970s, is a striking example of sculptural modernism. With its fluid, tubular steel frame and organically contoured seat, the design reflects Chan’s signature fusion of Eastern aesthetics and Western innovation. The cantilevered form gives it a light, floating appearance, while the original upholstery adds warmth and texture. Produced in very limited numbers, the SZ15 is a sought-after collector’s piece that rarely surfaces on the market. A bold statement chair that balances art and function, perfect for design purists and modernist interiors.
