Pleated Pleat uses a special material (Tyvek, patented by DuPont), similar to paper but more resistant, that when skilfully pleated and filled with rigid polyurethane foam can be used to create endless variations of padded seats. The advantages are evident: no moulding and no need for internal structures or even covering. Yael and Shay, Israeli but established in London, explain the transition from two to three dimensions: “We were fascinated by the fact that by pleating paper we can turn it into a stretchable surface. We tried pleating it in two directions (and not just in one as usually done with skirts) so it can be stretched into a dome shape.” Elena Sommariva
