The living room is a high utilization space in the living culture, and the furniture frequently used in the living room is the sofa. Different people prefer sitting, and some prefer anti-sedentity, while others prefer sitting. Even if they wanted to sit in a sitting position on the sofa mat and relax, they had to rest on the floor because of the narrow width of the sofa mat.

To be used by these people, the width of the sofa mat was advanced forward by the thickness of the backrest so that the sofa mat could be rested in a seated manner. The sofa's mat is so wide that it can be used as a single bed. The sofa mat can be removed and a functional ondol mat can be used as a single ondol bed in winter.

Electric sofas have been used in Europe and the US for some time. Conventional electric sofas, however, were sofas with fixed mats, backrests and calves.

Electric sofas with such a structure were mostly apartments, and many Korean homes lacked space. Even if the backrest is fixed and there is a sofa with the sofa mat moving forward, there is one electric cylinder in the center or one electric motor mounted on the armrest to move by using the recker gear. It is composed of a sliding upper frame and a lower frame that fixes the electric cylinder, and not only is heavy, but also the lower frame and the upper frame must be aligned by engineering mechanisms, so that when the electric cylinder is pushed or pulled by the sofa mat, eccentricity does not occur. , The upper frame could be sliding. The problem is that the sofa cannot be designed for three long sofa mats, such as three, four, five or six, etc., the components cannot be modular, and the sofa must be made in one piece. It was uncomfortable.
