Our deluxe kit consists of all products in the intermediate kit, with the addition of the new Disc Prolapse Simulator ZJZ-222-P. The prolapse simulator allows both students and instructors to have a hands on approach in showing the sort of movements that may cause a herniated (slipped) disc, meaning it is now possible to show in graphic detail the effects of poor postures on the spine. This comprehensive kit is suitable for all levels of course and allows instructors to show all elements of back problem prevention in interesting and memorable ways.
