Abstract: A dummy body for testing of sitting, reclining and supporting cushions of upholstered sitting and reclining furniture, by means of which a complex interaction of various muscles can be simulated, true to reality, in a variable way, and which is distinguished by a cost-effective and simple construction. The worn parts can be replaced quickly and cost-effectively. The dummy body has a plurality of discs arranged adjustably next to one another and having different material properties in terms of the degree of hardness. Therefore, the muscle hardness of a dummy body to be simulated can be set variably according to a predetermined test program.
