XXXX_Sofa by Yuya Ushida
for Ahrend


Following our video interview with designer Yuya Ushida, this film demonstrates the earlier bamboo version of his Sofa_XXXX expanding seating system, which is made from thousands of components. Ushida developed the concept while studying at Design Academy Eindhoven.

Here are some more images of Yuya Ushida's expanding plastic sofa for Dutch company Ahrend:

Called XXXX_Sofa, the piece is made of 8000 sticks and 2000 rings that snap together.

The components are injection-moulded from recycled plastic bottles.

A stool version with 600 parts is available in kit form.

Here are some more details from the designer:

Dutch office furniture company Royal Ahrend NV is producing transformable furniture XXXX_Sofa and XXXX_Stool designed by Yuya Ushida.

XXXX_Sofa by Yuya Ushida for Ahrend

XXXX_Sofa/XXXX_Stool are industrial version of Ushida's Graduation project SOFA_XXXX for the exam at the Design Academy Eindhoven in June 2010. It was rewarded with the maximum level of 10 and the graduation was cum laude. This original model is handmade of about 8000 bamboo sticks and 2000 rings. The basic idea is that a chair can change into a sofa by a simple movement without any tools...

A chair becomes a sofa, and a sofa becomes a chair.

“Whenever I see it the beauty of the simple geometrical structure and its repetition always fascinates me. SOFA_XXXX is made of just 4 different lengths of sticks, rings and joints. the parts on their own don’t seem to be special, but when put together in a regular pattern their beauty appears. It can be contracted, which makes it easier for transportation...”

This was a my concept for SOFA_XXXX, which was my graduation project 2010. I used bamboo sticks and It was all hand made. Therefore it is hard to mass produce. However I prefer to focus on our daily life rather than making an art.

In order to use as a daily life object, we chose to use plastic injection molding. And you can click in to build it up. It consists of only 8 elements, you can make many shapes. (e.g. Sofa, Stool, Table and Bench etc...)

Also it is used genuine recycled PET, no glass fiber for strength. I wanted to do something with the PET bottle that overflows in our society.

My design motto is to make people happy while using things that I have made. Also, I would like to translate a beauty that is surrounding us into my objects.

XXXX_Sofa and XXXX_Stool suit this very well. Of course these can be used as a furniture, but also you can enjoy the geometrical structure like your own Eiffel tower! Then, if you put together it by yourself, I am sure, it definitely will be existence more than furniture for you.

XXXX_Stool is made out of around 600 parts (sticks and rings)

    As nice as this might seem to be in concept, in reality 8000 compents….for 1 sofa is totally crazy. You cant even use the green card with the material becausew the energy to produce all those compenents out weighs the 'eco' material

  • HydrangeaGirl

    Imagine trying to dust those though …

  • Mario De Vries

    In some way I agree with eco buster. I think the amount of plastic used for one sofa is a bit over the top. Wether it is recycled or not, it would be at least a better gesture to use a bit less plastic.
    Concerning esthaetics; it looks mathematical and complex which is nice.
    If I order one, will it be preassembled???

  • Priscilla Seminario

    I love the concept behind it! I think in this case, is not about dusting it or the practical use for it, but the way he explored new ways to compose an everyday object, is as playing with mecano, genius!!!

  • As product design it is not very appealing —frankly, I wouldn't feel like sitting on it.

    On the other hand, I really can envision how this sort of approach could some day enable the consumer to order some product online, and subsequently print it with a home 3D printer, once these become cheap enough to be ubiquitous.

  • rosko

    Well, that's a real coin-trap :)

  • I love the design concept, but it looks really labor intensive and ultimately I question how comfortable it would be as a piece of furniture. That said, the idea of taking a small component and multiplying it on a large scale to make interesting and intriguing design is fascinating and really requires the designer to think through the design on a micro scale. Great study!

  • guest

    Doesn't seem very comfortable

  • osker wright

    looks like michael young's link objects / stuff , in principle ….as trends go

  • If this were the superstructure of a building it would probably translate well if they were steel girders. It would probably be a lot stronger too, because it is made of triangles while most buildings' underlying structure is a bunch of boxes. I only wish the photos gave a better description of what is going on with the structure. It looks like nested/tessellated octahedra (or at least related) to me but I can't tell.

    This can be built using poly lactic acid based polymers so it is compostable to some extent, and mass assembled via robotic or automated fixtures to eliminate the labor equation. Energy is also a non issue, a few solar panels or wind turbines powering the electric plastic injection molding machinery, and robots, this could be a ultra low impact fully sustainable design.
