By using a folding technique, an air-consisting pillow is first enclosed by a platter of eternit and blown up afterwards. Thereby evolves the distinctive shape, which forms a very stable hollow body in the hardened state due to its bulges and folds. This simple technique uses the characteristics of the building material eternit and combines its high stability with a stunning lightness. Because of the little mold constraint of this manufacturing process, each piece of furniture becomes a one of a kind, since each pillow of eternity differs slightly from the others. The copper or brass electroplated steel frames support the light appearance and keep the pillow firmly in its position.
