Pleated Pleat by Raw Edges
I was almost certain we had featured the Stool, chair and lounger upholstered with pleated Tyvek by Yael Mer and Shay Alkalay of Raw Edges Design Studio here already…Not so. Pleating allows flat, non elastic materials to become a springy, three dimensional cushion when filled with soft polyurethane foam. That is what they did here.
Notably I’ve found an entire blog dedicated to pleating: Pleat Farm, which to my pleasure, has a Chairs section as well.
