Abstract: A device for resting upon the seat of a vehicle for receiving the feet of a child in a child's seat or the like on the vehicle seat comprises an upper receiving surface which is supported by a support surface relative to the seat so as to be inclined slightly forwardly from a rear edge toward an apron at a front edge which overturns the front edge of the seat and extends downwardly therefrom. A side wall around the receiving surface prevents liquid from running to the sides and confines the feet of the child onto the surface. The device is formed by rotational moulding so as to form a hollow body with a flat lower supporting surface, a rear upstanding wall and the receiving surface which are triangular in shape with a hollow interior.
