Winner: Seating design of the year 2025. Paul Crofts Studio has designed Knit One for Isomi, a 3D knitted modular seating system made from recycled post-consumer waste.

Knit One is a groundbreaking modular seating system that redefines upholstery from the inside out. Foam is replaced by air while traditional upholstery methods give way to 3D-knit textiles, radically reducing material waste.

Made using recycled post-consumer waste, the Knit One system showcases a continuous, visually solid volume that mimics the softness and fullness of upholstered furniture while being made almost entirely of air and knit.

Built on a lightweight metal frame designed for flat-pack shipping and easy local assembly, Knit One expands Isomi's portfolio of circular, environmentally responsible products, setting a new standard in material-driven innovation.

Judge comments: "This chair design not only functions effectively but, crucially, it is free from toxic and polluting petrochemical-derived foams. The comfort is derived from stretching the textile over the metal frame, which in turn informs the aesthetic. The design is simple in its material use and easily repairable. It sends a strong message to the industry that the construction of upholstered furniture needs a serious rethink."
