Abstract: A prenatal mattress enabling a pregnant woman to lie more comfortably and safely upon her abdomen during the pregnancy term is disclosed. The mattress can comprise a lower layer of cloth carrying releasable fasteners, an abdominal cushion, a head cushion, and an upper layer of cloth. The abdominal and head cushions are disposed in appropriate locations between the lower and upper layers to support the respective portions of the body of a particular user. The cushions can be fillable to an extent desired with a suitable fluid, and can be placed between the sheets of cloth and attached to the fasteners carried by the lower layer by means of coordinating fasteners carried on lower surfaces of each. In use, the pregnant woman lies frontally downwardly upon the mattress, her abdomen and head being placed upon their respective cushions.
