Disclosed herein is a pocket spring structure for a bed mattress, in which a rigid support capable of resisting compressive strength due to applied load is further integrally formed in a partial region of a spring mounted in a sealed pocket, thereby preventing deformation of the spring and increasing its durability. That is, the present invention provides a pocket spring structure for a bed mattress, in which a separate rigid support capable of resisting compressive strength due to applied load is integrally formed in a partial region of a spring mounted in a pocket formed of fabric to prevent deformation of the spring, even when large and small loads are irregularly and repeatedly concentrated on the spring, thereby increasing its durability and further improving the quality of the bed mattress.
