A neonatal retention or support system including a horizontal base configured for at least one of attachment to or placement on a mattress of a bed, and a wall attached to and extending vertically from and at least partially around the base, the wall comprising at least one pair of hinges to allow the retention system to follow an adjustment of the bed. The wall is flexible inwards to allow a person to lie on the bed, and inflexible outwards so that an infant disposed within the retention system is prevented from falling from the bed.

A safety bed for children and adults who may special needs includes a frame having a base frame, an upper frame and four vertical poles between the base frame and the upper frame at their respective corners; a mattress support structure supported by the base frame; and an enclosure attached to the frame, said enclosure comprising a ceiling, a base and four walls. A mattress within the enclosure is supported by the mattress support structure so that a sheet may be attached to the four walls of the enclosure at a position approximately equal to the top of the mattress. The enclosure may include a variety of device for monitoring and communicating with an occupant of the bed, including a camera, a light source and other sensors that may be remotely controlled over a network.
