A child- or infant-sized safety seat is disclosed with relatively horizontal seat and relatively vertical back support elements designed with flotation effecting materials sufficient to keep said child or infant at the water's surface and with critically positioned and apportioned (relative to the weight of the back and seat support elements and the anticipated weight of the child) counter-weight effecting materials to result in that portion of the vertical back support element supporting the child's head and shoulders well above the water's surface. The safety seat is preferably constructed by injecting a semi-rigid, resilient polyurethane foam into a die cast mold into which the weight materials have been pre-positioned to result in the up-righting of the safety seat at the water's surface, and the foam, upon rising and curing, forms around the weighted material to fix its position.
A flotation safety seating device comprising a relatively horizontal seat support element and a relatively vertical back support element each of which are at least partially constructed of a flotation effecting material and further comprising weight effecting material approximately centrally positioned below the seat support clement in an amount in proportion to the flotation effecting material to result in causing the safety seating device to be in an upright position when floating in water with at least the upper one-fourth of the back supporting element above the water's surface wherein the weight ratio of the seat and back support elements to the weight material is about 0.75-1.5:1, respectively.
