Abstract: An arrangement of a modular interior furnishing system for rooms consisting of at least two pieces of furniture or household appliances on at least one platform is described, wherein the at least one platform has a base and a support element mounted for simultaneous translational and rotational movement relative to the base, the base and the support element having planar bearing regions facing one another, guide cam tracks being formed in one of the bearing regions and guide cam tracks being formed in the other of the bearing regions, guide elements guided in or on the contours of the guide cam tracks are arranged, so that the support element can be rotated relative to the base at least partially positively guided in one of two possible opposite directions of rotation and can be moved in a predetermined direction of translation, the guide cam tracks are shaped in such a way that when torque acts on the support element, the support element is rotated from an initial position via an intermediate position in whi
