Simmons Model no 6407 97 62 Mattress Supports

This looks like a corner-mounted mattress support bracket used on older Simmons cribs. These brackets typically attach near the crib posts and support the metal spring frame at each corner.

On many Simmons models from that period, the crib mattress support system used four metal brackets, one at each corner, along with a spring frame or wire grid. The hardware may be described as a mattress support bracket, spring frame bracket, or corner support bracket.

Exact part names and designs can vary by model and production year, so the model number is usually the best starting point when comparing older Simmons hardware. Because older cribs may not meet current requirements, it is also smart to review current crib safety standards before making any decisions about an older crib.
