Sofa_XXXX is the creation of German designer Yuya Ushida, is a unique expandable sofa made from 8,000 wooden chopsticks.

Showcased during the Designers Fair at the IMM Cologne 2011 exhibition, Sofa_XXXX attracted a lot of attention because of the unusual medium Ushida used, and its ingenious folding mechanism. The expandable and retractable sofa was created from 8,000 wooden chopsticks, individually cut to four different lengths and sanded to just the right angle, connected with metal rings and plastic joints. German-based designer Yuya Ushida spent three months working on the Sofa_XXXX project, but the stunning end result was definitely worth the effort.

Perhaps the most remarkable thing about this one-of-a-kind chopstick sofa is that it can actually support up to three 70-kg-heavy people at any one time.
