US Patent 9155974 Play mat and system

A play mat is formed from a cushion material enclosed by fabric. A flexible rod-like element with a substantially continuous outer surface may be fixedly coupled to a portion of the mat. A slidable member is slidingly coupled with the rod-like element. In some cases, at least one article is coupled to the slidable member. The article includes a first item coupled to a second item by a length of material. The first item may be resilient so that the article is coupled to the slidable member when the first item is compressed and passed through an opening of the slidable member so that at least a portion of the length of material is positioned within the opening.
