‘sofa-dress’ is a job of space design and a suggestion of furniture design. The act of putting on the clothes of the “sofa” on the existing chair in itself makes the previous object become a little more cushiony furniture and it also can achieve an intention as a unified space with the same cuticles. The ‘sofa-dress’ projects the past objects through the rays of space, which makes a new present without removing the past completely. The black and transparent cuticles reveal the past objects in secret. Its material is the special blowing-type urethane foam and plays a role in screening the rays and simultaneously getting rid of a feeling of weight. Simply beyond the cuticles covering the chair, ‘sofa-dress’ holds an intention of a new-styled design experiment with its own form and mass.
