Abstract: A baby crib includes a bed frame structure, a fabric member mounted on the bed frame structure to define a surrounding wall around the bed frame structure, and a plurality of positioning posts mounted on the fabric member. The bed frame structure includes a plurality of upright tubes, each of which has a tube wall defining a receiving hole and having a slit that extends along the length of the tube wall and that is in spatial communication with the receiving hole. The positioning posts are inserted respectively into the receiving holes in the upright tubes. The fabric member is clamped between each upright tube and a corresponding positioning post, and extends outward through the slit in each upright tube.
