Stack is a cushion casually tossed on top of another cushion. The sofa is merely a magnification of this all-too-common scenery. In order to convert the soft features of a cushion, an object with a frameless structure, into a structured piece of furniture, hidden elements were added to join the stacked elements together, securing them in such a way as to remain invisible. Though the placement of the cushions might appear random, it actually took careful consideration and numerous prototypes to determine the best configuration. The production was conducted with extra effort and care in order to lend the design an effortless and care-free look.
