Pack Chair Grows Before Your Eyes

French designer François Azambourg, known for his inventive creations has developed an ingenious transforming chair that grows into full form before your eyes. The Pack Chair comes in a small plastic package, and shapes itself from a compact flat block into its final form through a chemical reaction.

Design Boom explains:

..Designed with the intention of selling it via mail order, the chair is fabricated with an internal airtight polyester cloth pouch and a double lining that contains a two-part liquid polyurethane foam. activating a switch on the side of the flat chair, the user can start the release of the material, causing it to combust and fill the inside. the ‘pack chair’ will get its ultimate shape when the double-walled textile fibers harden on the contact with the emulsion of these two chemical products. perhaps you’ve seen a demonstration of polyurethane ingredients being mixed together, causing a very rapid and almost violent foaming reaction…within a few seconds the form is rigid.

At the moment the Pack Chair works, but is only a limited edition concept design. You can catch it at the  Design in Mutation exhibit at the Design Centre of the UQAM in Montreal, Canada until March 1st, 2009.
