Sit on paper.

From USA, designer's comment: "cardboard stool folded from 4'x4' cardboard sheet. this stool developed from a folded paper design exploration involving many small folded joints. scoring in the cardboard allows the sheet to collapse in on itself. clear tape secures the exposed edge."

From Spain, designer's comment : "foldable, comfortable, easy to move around and resistant. this folding chair, made of cardboard, is a versatile, easy and cheap to manufacture, made in one piece."

From Belgium, designer's comment: "private park is a foldaway seat to take out to the garden, the park or the beach. unfolded, it creates oneself a personal space in the outdoor environment. the angle of the backrest can be adjusted to any position thanks to the little feet that dig into the ground. following the seams of the quilting, private park folds up into a little bag (a triple seam indicates each fold); handles incorporate to the quilt makes it is easy to carry it around. sliding the backrest out of the canvas, private park can be machined wash. material: quilted cotton, canvas & plywood."

From USA, designer's comment : the name of this piece is origami chair. the construction of the photographed
prototypes is from polycarbonate and polyester mesh- polycarbonate stiffeners sandwiched between 2 layers of mesh. the chair folds together from a single sheet into a structural volume. due to the semi-transparent nature of the materials, the internal fold structure remains visible. the strength of the piece is in the clever series of folds that provide the structure and crisp angularity of the finished form.
