Abstract: A mattress like structure is provided which is designed to not only give good support to an infant while sleeping, but may hopefully reduce the possibility of the infant suffocating while sleeping on its stomach. It includes a generally rectangular shaped rigid frame with a resilient, flexible fabric of special construction tightly stretched over the frame to form a top and bottom surface. The fabric is of an open mesh type with relatively large openings to provide excellent air flow to the infant. The non-open area of the fabric is such that it will support the infant in a very comfortable manner without making any creases or lines in the infant's skin. Moreover, the openings, although relatively large are not so large that the infant's fingers can be caught in the openings. The special fabric is constructed in the form of a generally rectangular shaped sleeve closed at one end and provided with a zipper or other closure means about a portion of its perimeter.
