The Nest is a patented medical-grade foam-mattress sleep system. It has provided pregnant women in the United States and Canada with a restful night's sleep since 1994. Most pregnant women experience sleep deprivation associated with the discomfort related to distention of the abdomen. The problem becomes pronounced as the pregnancy progresses and is most significant during the last three months. Frustration and anxiety associated with sleep deprivation frequently results in elevated maternal blood pressure, which may complicate the pregnancy. The new, innovative Nest sleep system from Nest Corporation is the answer to sleepless nights and discomfort during pregnancy!
