This is so simple yet very effective. One of those why-didn't-I-think-of-it things!
This clip is taken off the Youtube posting of Children's Publications Co. (CPL), a publisher from Taiwan that focuses on children's books, videos and merchandises. I do not think this is one of their books, but it is really good of them to share.

Flexible Love

FlexibleLove™ 16
64cm x 56cm x 22.5cm(Collapsed)/720cm(Extended), recycled materials (post-consumer recycled paper and post-industrial recycled wood)
I watched the designers of Flexible Love present their product on a Taiwanese variety show and really wish to share! The Flexible Love concept is an accordian, honeycomb structure, which can be stretched to seat as many as sixteen individuals. Made entirely from recycled materials the seating uses pre-existing production processes to reduce environmental impact during manufacture. currently, Flexible Love comes in 3 sizes that seats 16, 12 and 2. Excluding the miniaturised version. See the video below for the varieties of the system.
