Generally, when people are sunbathing on the beach, on the beach, beside the swimming pool, or on the grass in the suburbs, they often lay some items on the ground or on chairs, such as towels and straw mats. However, towels do not have a frame support, are easy to roll up, and are not easy to lay flat on the beach. Although the woven mat can be laid on the beach relatively easily, it is difficult to clean after use and it is easy to break. In order to overcome the above disadvantages, two relatively similar designs have been proposed in the two patents of US Patent No. 6,073,283 and International Application No. W09959452A, both of which have a two-layer structure, and the lower structure includes an elastic member, which is supported by a cut-out oval. In the shape of the surface layer, the lower layer forms an oblong frame structure, and an upper cushion is set on the frame by a zipper or an elastic rope. Although the above structure has many advantages compared to towels and straw woven mats, it still has the following problems: 1. Since the shape of the entire mat is determined by the shape of the lower structure surface layer, if the lower structure surface layer is removed, the cushion It will become round, and it becomes difficult to fold. 2. Since the lower layer is used to fix the frame, cleaning the concrete layer is very inconvenient. 3. The above structure can only be folded into one-third of the outer diameter of the original display frame, and cannot be reduced. Summary of the invention
