Sponge, air mattress, and sponge fabrication process

Abstract

A sponge, an air mattress, and a sponge fabrication process are provided. The sponge is provided with cutting seams. When an external force is applied, the sponge is expanded, and gaps are formed. The gaps are equivalent to holes of an existing sponge block formed by a conventional vertical punching method. Compared to an air mattress that requires punching the entire sponge, the air mattress only requires cutting the sponge without punching holes, such that corresponding gaps (i.e., corresponding conventional holes) are formed when the sponge is expanded by an external force. After the sponge is combined with an air mattress body, a corresponding pattern is formed. The sponge avoids waste materials formed by punching holes, and is environmentally friendly.

Dependencies are inferred from the claim text.
