Vintage teak wooden ladder chairs, 1960s

Set of 4 beautiful high chairs made of teak wood and plywood from the 1960s. The chairs have a ladder backrest and a curved shell-shaped seat covered with burgundy red leatherette. The chairs are often attributed to cees braakman for pastoe or topform. It is unknown to me who the maker is, but they are certainly cool! In very good vintage codnition with light traces by age and use.
