Abstract: A baby swing seat having a generally horizontal seating member with top and bottom surfaces, a generally upright back support and two arm rest support members. The detachable leg extension is adapted to be placed adjacent the seating member top surface and adapted to extend generally horizontally and forwardly of the seating member, thereby supporting the legs of a baby seated in the swing seat. The seat may also be configured with a cross-member extending between the support arms to provide additional positioning support. Additionally, the rearward end of the seat may be of increased thickness to provide additional support.
