[0003] In general, a sofa is positioned at a predetermined height from the ground, includes a seating part on which a user can sit on the top, a backrest formed at a rear side of the seating part to support the back, and armrest parts formed on both sides on which arms can be placed, and is filled with a filler having cushioning force to provide comfort.
[0004] Such sofas have recently been manufactured and sold in small sizes for use by children. However, since their function is limited to that of a chair, there is a problem that, despite being expensive products, children easily lose interest and tend not to use them.
[0005] Meanwhile, in general, a trampoline is an exercise apparatus that allows a user to jump into the air on an elastic or resilient mechanism, and generally includes a trampoline mat exhibiting elastic force coupled to a central portion of a support frame generally made of steel. A trampoline mat is coupled to the support frame through a connecting member composed of a spring or an elastic band to attenuate and absorb a dynamic load that is applied to the top.
[0006] That is, when the weight of a person falling from above onto the mat of a trampoline mechanism is applied, the trampoline mat vertically moves due to the elastic force of the connecting member that connects the mat and the support frame, which is suitable for growing children to enjoy balance exercises combined with play.
[0007] Therefore, when the above-mentioned trampoline function is applied to a sofa, children can easily take interest and even indoor play can be enjoyed using the sofa, so there is a need for improvement in this regard.
[0008] The above description is the background for helping understand the present disclosure and does not means the related art well known in the art.SUMMARY
