PURPOSE: A multi-purpose mat set is provided to use a mat as a sofa or a bumper bed by folding the mat while using the mat for a baby or a noise-proof purpose. CONSTITUTION: A bumper guard(100) is changed to a folding state or an unfolding state to be folded in half. A part of a vertical frame(111) of the bumper guard is cut. A folding portion(120) for connecting the cut part is formed on the bumper guard. A mat(200) can be folded in plural layers. The mat is inserted to be matched with each internal standard of the folding state and the unfolding state. A line-shaped connection member is attached to a pair of connection member fixing portions placed on the bottom of the inside of the bumper guard.
