Created by Japanese designer Kei Harada, the sofa you see above is similar to the structure of marshmallows.  Because of this structure, it allows a user to explore different sitting positions.

Although it is not exactly made for children, Harada says, “although this sofa was not built specifically for children, it was my impression that the children intuitively understood my intentions of inducing motion through the sofa”

The official name of the sofa is the ‘O’keeffe’ sofa.
