[0002] A folding chair is a type of seating that can adjust its shape, function, or structure according to user needs or changes in the environment. Its design aims to enhance the user experience, save space, or adapt to various usage scenarios.

[0003] Folding chairs are typically designed to be lightweight and easy to fold, making them convenient to carry and store. They are ideal for outdoor activities or spaces with limited capacity. When folded, the chairs are compact and can be easily stored in cabinets, car trunks, or backpacks without taking up too much space. Folding chairs are suitable for various occasions, such as camping, picnics, family gatherings, outdoor concerts, outdoor movies, and sporting events, providing users with flexible seating options. With the development of design, many folding chairs are not only practical but also stylish and beautiful, adding to the aesthetics of the environment.

[0004] In the existing technology, folding chairs have the following drawbacks: the folding function of the chair is often relatively simple. When it is necessary to adjust the chair to be unfolded and seated, the height of the seat is fixed, which leads to discomfort in the sitting posture, or the person can only use other objects to support the seat, making the chair posture adjustment operation cumbersome. Therefore, a multi-functional deformable chair is proposed to solve the above problems. Utility Model Content
