The Peacock Chair is Studio Dror's first collaboration with Italian furniture manufacturer Cappellini. Designed by Dror Benshetrit, the chair's form is created out of three sheets of felt and a minimal metal frame. The folds of the felt are woven tightly to form a structured lounge chair, with no sewing or upholstery involved.
Looks like industrial felt to me gathered together to create those folds.
