The Inception Chair by RISD student Vivian Chiu is a series of ten interlocking chairs made of ash, meant to mimic the dream within a dream concept from the 2010 film Inception. Each chair has hand cut grooves on the inside edges of its seat frame as well as notches in the seat back. The mechanism works so that the pegs fit into the grooves of the chair one size bigger and slides into place so that the horizontal edge between the chair seat and back line up. The simple mechanism allows the chairs to be taken apart and put together with ease. Although the concept behind Chiu's chair design is based on a dream within a dream, the chair displays a perception of perspective when viewed from the front and back elevations also.
