Abstract: An infant sleeper is provided that has raised wall portions positioned to approximately correspond to the center of mass of the infant so as to provide maximum retention support and security to the infant. The raised wall portions, in combination with a horizontal surface on which the infant rests, secures the infant to the bed. The head can be inclined at an angle so that the head of the infant can be kept slightly above its foot. The portion of the bed that lacks the raised wall portion provides as little obstruction as possible to the head of the infant so as to reduce potential feelings of claustrophobia as well as possible obstructions to breathing such as from blankets. Hence, the present invention combines a secure place for an infant to sleep with a sense of openness and freedom. It is believed that this position allows the infant to rest in a more correct anatomical position so as to ameliorate potential respiratory conditions and especially sudden infant death syndrome (SIDS).
