Abstract: A crib is provided which includes a dropside mounted to endboards of the crib. The dropside is secured to opposing pairs of tracks. Each lower track includes a pair of generally parallel grooves, one of which extends substantially below the other. The dropside is coupled to the lower tracks by a pair of spring bracket assemblies, each of which includes a laterally extending spring arm. The spring arm includes a continuously curved upper surface. In order to prevent the inadvertent displacement of the dropside, the relatively short groove includes a portion of reduced width. Each spring bracket assembly includes a longitudinally extending pin which may be moved easily through each groove except the groove portion of reduced width. Assembly of the crib is facilitated by coupling one of the spring bracket assemblies to the dropside as the final step of mounting the dropside to the crib.
