German based designer Yuya Ushida has recently completed Sofa_XXXX, an incredible product that is both contractible and retractile, which makes it highly versatile. According to Co.Design, the designer used no less than 8000 chopstick for this uncommon sofa, cut into four different lengths in order to form X-shaped components that could build the structure. All the elements war joined perfectly (check out the photos for amazing details), so much so that up to three people of 70 kilos each can sit together on the sofa without it being caused any damage. Moreover, the unusual looking furniture piece can be easily transformed into a chair and then back again by expanding (pulling) and contracting (pushing) the structure. We’ve also uploaded a video with a demonstration. Have a look and let us know what you think of this crazy design project.
