As with the base, history also serves as a backdrop for Permobil’s new Corpus 3G seating system. Developed in conjunction with the original Corpus designer–world-renowned Swedish seating expert Bengt Engström. The Corpus 3G uses Engström’s concept of Interactive Counter Pressures as a blueprint. Incorporating the latest in ergonomic design as well as electrical and mechanical technology, the M400 Corpus 3G fuses form and function.
