Abstract: An inclined pulmonary-assisting mattress with a profile assisting infants and small children with respiratory problems and other adverse medical conditions, including asthma, wheezing, colic, SIDS, ear infections, and acid reflux. It can be used with a crib, bassinette, or other defined infant sleeping area, as long as it appropriately fills that sleeping area to eliminate all injury, entrapment, or breathing obstruction risk for the child using it. The mattress is not used on top of a crib mattress, but instead replaces a crib mattress until the child recovers or outgrows the breathing difficulty or adverse medical condition. At such time, the inclined pulmonary-assisting mattress is removed and the child is allowed to sleep on a regular crib mattress or other substantially horizontal surface. Intended applications include, but are not limited to, use in hospital neo-natal units, children's nurseries, and by parents of infants suffering from breathing or digestive issues.
