Abstract: A mesh crib bumper enclosure having four connected vertical mesh fabric panel sections installed in a crib by suspending it from the top and bottom corners and securing it to the crib's four corner posts, the same way ropes are suspended in a boxing ring. The mesh crib bumper enclosure's four mesh fabric panels are stretched tightly between the four corner posts using a locking fastening means. The mesh fabric panels allow air to circulate through the crib, preventing the baby's exhaled carbon dioxide from building up in the crib cavity and the possibility of Sudden Infant Death Syndrome (SIDS). Each of the taut mesh fabric panels acts a trampoline surface preventing a baby from impacting the crib's balusters or getting lodged between the crib's vertical balusters and rails. Each of the mesh crib bumper enclosure's four corners receives vertical support members for vertical compression structural integrity.
