A joint between a bed frame and a fabric member is revealed. The bed frame includes a plurality of vertical tubes each of which includes an assembly space with a narrow opening. A connection portion connects a plurality of positioning blocks to the fabric member and the positioning blocks are corresponding to the assembly space of each vertical tube. Thereby positioning blocks are mounted into the assembly space from one end of the vertical tube and the connection portion is extending outward through the narrow opening of the vertical tube. Each positioning block is unable to be released from the assembly space axially due to that the outside diameter of the positioning block is larger than the width of the narrow opening. Thus the fabric member and each vertical tube are connected firmly.
