Dutch designer Mario Minale created this Red Blue LEGO Chair made entirely out of LEGO bricks and aluminum. Due to the aluminum frame, the LEGO chair can be used as functional, albeit uncomfortable and cushion-less, seating. The chair is 84 cm or 33 1/8 inches high and was manufactured by Amsterdam-based Droog Design. The extremely limited edition chair is on auction at Phillips de Pury and Company, a New York-based auction house, and is estimated to fetch between £20,000-25,000. Only five editions of the LEGO Chair were made plus two artist’s proofs and one prototype.
