Chicago based designer Dan Goldstein created a minimalist chair, named Re-Ply, made of a steel frame and discarded cardboard boxes. A chair which reminds me a bit of the of the Hardoy chair (butterfly chair).
Goldstein discovered a way to mold 4 plys of cardboard into a comfortable shell. The fibers of the cardboard fibers are strong enough for the chair's construction. The shell is attached to a triangular steel base with two bolts. The bolts make it possible for one to gently rock the chair.
I love the concept that the shell can be created from up-cycled cardboard and easily can be recycled after years of use. The use of cardboard also makes it possible to easily customize the shell yourself after purchase.
