Abstract: A seat for a child's swing is of the type having a plate-like substantially rigid member to bear the weight of a user sitting on the seat, and resilient polymeric material secured to the plate-like member. The resilient polymeric material extends beyond the outline of the plate-like member to form a border around the edges of the plate-like member, and forms a peripheral dependent skirt of substantial thickness. To achieve greater safety in use, the border includes a hinge-like portion of the resilient material, the plate-like member in the region of the hinge-like portion is configured to provide room for the dependent skirt to hinge beneath the plate-like member, and in an impact between the edge of the seat adjacent the hinge-like portion and an object, the skirt is progressively deformed and forced to hinge inwards against the resilience of the hinge-like portion.
