Designer Tokujin Yoshioka takes the notion of negative space to the extreme with the ethereal, well-nigh invisible, Prism Chair for Glas Italia.

First shown at Milan in 2014, Prism is sublimely simple. Seven sheets of thick, highly transparent pieces of glass come together to make the most elemental form of a chair.

However, the transparency that is the Prism Chair’s calling card is undercut—and enhanced—via the chamfered edges of the individual glass sheets.

Therein lies the prismatic phenomena, as the beveled edges reflect and refract the light into the visible spectrum we know as a rainbow. It’s a beautiful effect—testament to Yoshioka’s assertion that Prism is “a chair like a shimmering sculpture… miraculous expression is brought by the refraction of light.”

Prism’s companion pieces include the Prism Sofa and Prism Table.
