Description
Technical Field
[0001] The utility model relates to the field of sofas, in particular to a detachable sofa. Background Art
[0002] The inner frame of a traditional sofa is usually made of wood, steel, etc., and then a layer of leather is applied on the surface of the inner frame. The structure is mostly processed into an integral whole. Although the appearance gives people a feeling of being smooth and flat, the outer leather is easily damaged by external forces during daily use, especially in households with pets, such as cats, dogs, etc. Pets have a natural tendency to sharpen their claws. When encountering leather fabrics, they are easily damaged by pets, resulting in a significant reduction in the service life of the leather. However, the existing leather is designed as an integrated unit with the inner frame. When the leather is damaged, the inner frame can still remain intact, but because the leather is on the outer surface of the inner frame, the entire sofa can only be replaced, resulting in waste of use.
