The existing office chair seat cushion foam assembly is mainly foamed and cut into a specified shape, and then covered with an outer skin before being put into use.

[0003] The existing anti-tilt seat foam cushion is a polymer material with good softness, so it is easy to collapse when people sit on it. Therefore, a support plate is usually installed at the bottom of the foam cushion to support it to prevent it from collapsing. Since the existing anti-tilt seat foam cushion does not have a limiting mechanism, when the force is uneven and one side is too heavy, it will tilt during sitting, affecting the comfort, so it needs to be improved.
