Abstract: A modular mannequin has a plurality of individual mannequin sub-parts and one or more flexible couplings. Each of the flexible couplings is configured to releasably connect two or more of the plurality of individual mannequin sub-parts to one another. Further, one or more of the individual mannequin sub-parts is each configured to receive at least one removable material. The modular mannequin may improve the ease of which a bariatric mannequin, i.e. a mannequin having a sufficient size and/or weight to simulate an obese human, is transported and/or stored when not in use and may improve the simulation of an anatomically correct weight distribution in such a mannequin.
