Inspired by the flexible accordion, designers have created these breathable furniture that can not only use as decorations, but also furniture. This paper sofa utilizes recyclable kraft paper with a concertina design to expand into a sturdy matrix to hold things. These materials are waterproof and the stretching ratio can reach 1:50. It can also fold back into a two dimensional form which is ideal for those that are short in space or that tend to move around a lot. Available in many sizes, the small size can use as single chair, the bigger size, sofa as well.
