The slat comprises a rigid thermoplastic resin having a cellular core and an integral solid skin along the longitudinally surfaces of the slats and a density of 0.4 to 0.6 g/cc. The upper and lower surfaces of the slat have a radius of curvature less than the width of the slat and, preferably, the upper and lower surfaces have substantially the same radius of curvature.
