A cradle-type swing seat includes two main parts: a steel tube ring made in two halves joined together to form an oval frame, and a resilient, flexible carrier formed by a cruciform moulding of resilient, flexible polymeric material. The frame halves have holes for fixing chain suspension parts and holes for fixing the two halves together. The carrier is fixed to the frame by apertures at its extremities so that it can be slotted onto the top ring. The flexible carrier is moulded flat and its limbs are folded up to fix to the frame. The completed assembly forms a safe swing seat for young children.
