Abstract

Disclosed is a component positioning structure for a combination sofa. The predetermined connecting section of each component of the sofa is mounted with wedge-shaped connecting elements. Once all the components are completed, the corresponding connecting elements of each two adjacent components are connected to facilitate assembly of the sofa and to ensure the components are accurately positioned. Moreover, the component positioning structure allows the components to be stacked for shipment, thus reducing the space occupied. If a certain component of the sofa needs to be reupholstered, this component can be detached without impairing the accuracy with which its wedge-shaped connecting elements connect with the corresponding connecting elements.
