The mat for the slide chair is usually called "slide mat" or "slide mat". This kind of cushion is usually made of soft and non-slip materials, such as foam, rubber or plastic, to provide a comfortable riding experience and prevent children from being injured during sliding.

Slide mats are usually placed at the top or bottom of the slide to provide additional cushioning and protection. It also helps to keep the slide clean and hygienic, because the slide pad can prevent children from directly touching the surface of the slide.
