‘tank chair 2’, 2007 (photo by ryan p)

jeff michael is an american designer who designed these two unusual chairs while attending ferris state
university in the us. the first chair ‘tank chair’ took inspiration from the heavy equipment rental shop at
which michael worked. using the principles most commonly seen in military tanks and construction
equipment, michael transformed the chair itself into a movable tread. using a three point structure,
the wood frame can rotate around the axels and support its user. michael liked this design so much he
decided to make a second iteration he calls ‘tank chair 2’ this newer model uses the same principle but
uses steam-bent maple instead of flat wood slats. the chair also uses a painted steel, cast iron and
urethane rubber on the internal structure. the designer put in over 300 hours to design and build
this chair.
