Free flow of fluids and digested food through the surface of Nettress and the ability to raise the head of the mattress decrease spitting up and prevent inhalation of regurgitated food.

The classical presentation of uncomplicated Gastroesophageal Reflux (GER) in infants is effortless, painless vomiting in a well appearing infant with normal growth. Usually simple parental education and reassurance is all that is needed. Thickening the baby formula is a simple measure. Elevation of the infant’s upper body is another measure good for reducing GER.

The ability to change the mattress angle and the unique quality Nettress' porous netting which enables liquids including regurgitated food and vomit to flow through the bottom of the mattress are important for treating GER.

Changing the mattress angle allows the baby's head and trunk to be raised, thus reducing regurgitation especially when combined with special or thickened infant formula. In addition since regurgitated food and mucus seep through the sleep surface the infant does not wake up in a "pool" of regurgitated food and the risk of inhalation of the food is decreased.
