Abstract: A portable infant protective bed for protecting an infant especially when sleeping in close proximity to a sleeping adult is disclosed. The bed is sized to accommodate an infant and is provided with a resilient bumper member around the perimeter of the bed. The resilient bumper is provided with spring-loaded switch activation members as part of an alarm assembly that is so configured to sense if an adult rolls on to the bumper member, the alarm either sounds a loud alarm or vigorously vibrates the bumper member, or both, if desired.
