yuya ushida: sofa_XXXX

‘sofa_xxxx’ by yuya ushida



‘sofa_xxxx’ by german-based designer yuya ushida is an expandable and retractable seating unit which transforms from chair to sofa. presented at designers fair at imm cologne 2011, the furniture piece is constructed from 8000 chopsticks which have each been individually cut to four different lengths and sanded to achieve the correct angles needed to build the structure. rings and joints are used to connect the sofa and aid in its adaptability and flexibility. overall, it took three months of work to finish the object. three people of 70 kg each, can sit on the sofa at any one time.

assembling the sofa

  • Incredible! Pure graft!

    Leslie Wilson-Rutterford says:
  • How much?

    cronun says:
  • fascinating~

    adoptme says:
  • This piece of craft really is something. Its only lack resides in the tediousness of its process, but so did umbrellas’ opening-system before it became a standard.

    why are there always people whose sole interest when looking at a project, is the price ? cronun can’t you at least place a few words about the sofa itself, or is your being perceived as a mere consumer satisfactory enough for you ?

  • fantastic! 🙂

    zmia_zmuk says:
  • Absolutely amazing! great work and patience

    solar says:
  • Great. Fantastic idea!!!!!

    sysscore says:
  • R the chopsticks used B4 the couch is made – so that it is made from recycled materials – how much cooler would that make the piece?

    meekangel says:
  • Que quemados estan estos muchachos….. Muy bueno

    Negro says:
  • a perfect pattern! magnificent work.

    ckbingol says:
  • Très beau travail!
    Mais le genre de processus de fabrication qui fait froid dans le dos.
    Me rappelle le cliché du travail forcé, sous-payé et abrutissant commun à tant de pays asiatiques!
    Je vois mal un artiste/designer européen ou américain se donner tant de mal.
    Yuya Ushida aime se faire du mal, dirait-on.
    Est-ce culturel?

    Made in Belgium says:
  • not sure about the ergonomy of the sofa. had they used damaged chopsticks or discarded chopsticks of something more recycable it would make it justified but getting a bunch of chopsticks, gluing them together to make a bigger component doesn’t really make sense. overall however it has great sculptural qualities and packaging would be so much easier than an average sofa. I am also interested in the price because this will have a bearing on the success of the product not just in terms of sales but because being a product – that should be one of the aims!

    bvel005 says:
  • actually i just realized that the chopsticks are not glued together – so sorry for any misunderstandings. ignore that part of comment
