The Knit One chair is a seating design that replaces conventional foam padding with an air-based support system contained within a knitted textile structure. The chair uses a tensioned knit surface that works in combination with internal air components to provide seating support, allowing the surface to respond to pressure and movement without relying on foam materials.
The knitted exterior is produced as a single continuous surface, forming both the seat and backrest. This textile shell is stretched over a minimal supporting frame, creating a suspended seating surface rather than a layered cushion. The use of knit allows the material to flex and adapt under weight while maintaining its form when unoccupied.
According to the designers, the chair explores alternative comfort strategies by reducing reliance on traditional upholstery materials. The air-supported structure is intended to distribute weight across the knit surface while keeping the overall construction lightweight.
