One rational form, infinite configurations; Haldane Martin’s SuperRational outdoor modular sofas are infused with graphic elements of the 80s. An intentional nod to Memphis, but in finishes that are more liveable. Light, open and geometric recycled stainless-steel frames playfully contrast with weighty, textured upholstery and retro piping (Crevin’s innovative environmentally considered fabrics).
“The SuperRational inspiration comes from a very specific memory. As a design student, I was intrigued by an image of the Memphis boxing ring sofa. Its’ proper name is Tawaraya, designed by Masanori Umeda. The photograph showed the whole Memphis group gathered on it, headed by Ettore Sottsass. It was described as a space for intellectual sparring. But it looked like the beginning of something far more intimate.”
The SuperRational collection comprises one-seater units and an ottoman, which can be repeated and arranged to form multiple compositions: A play pen to stretch out and sunbathe on, seating surrounding a fire pit, an L-shaped couch without the need to be permanently built in. The modular nature of SuperRational sofas offers flexibility to move with the seasons. The open wire grid frames are strikingly beautiful features that allow water to drain straight through, ensuring that cushions dry fast. The upholstery is completely separate from the frame, meaning covers can be easily removed, washed, or even replaced in the years to come. Like a fractal in nature, the rational form of the square is repeated at every scale – a super rational logic that holds all the way from plan to detail.
