A full size baby crib of novel construction which provides a range of vertical mattress positions about double those available in existing standard cribs for the dual purpose of safety and convenience. The construction comprises two balcony type modules at each end of the crib which are cantilevered from four generally upright inboard posts. On the side of the crib containing the gate, the two inboard posts are stabilized and made rigid by a plurality of stabilizers which are all functional parts of the crib. This permits a gate of about one-half of the standard width to move vertically from the top rail to the floor.
