Abstract: A seat for a childs swing is of composite structure having a first member, which is sufficiently rigid to bear the weight of a child, and a second member made of a compressible polymeric material. The first member is substantially laminar and the second member covers at least part of the peripheral edge of the first member. The force-deflection characteristic of the second member is such that, on any impact with an object, the second member initially deforms to conform with the shape of the impacted object and then deforms further to absorb the main energy of the impact.
