Maternity comfort mattress

A maternity mattress is disclosed which provides a cavity for accommodating the protruding abdomen of a pregnant woman as she lies in a frontally downward position upon the mattress surface. The maternity comfort mattress is essentially comprised of a foam core; of a cavity in the foam core for the enlarged abdomen of a pregnant woman; of a plurality of straps and a means to attach the straps to the foam core; and, of a removable cover to encase the entire device. Attachment and adjustment features are built in to the invention. These features include, but are not limited to, strips of material that have a loop and hook fastening means along two longitudinal sides of the mattress core and at each end of each of the straps.

Mattress structure

A mattress comprises a support plate having a plurality of mounting holes, a plurality of independent spring assemblies individually mounted to the support plate, and a cover enclosing the support plate and the plurality of spring assemblies. Each of the spring assemblies includes a tubular mounting member fixed to the support plate preferably by snap-fit through a mounting hole in the support plate, a sliding cap axially movable relative to the mounting member, and a spring acting between the mounting member and the sliding cap, wherein the spring is axially compressible when the sliding cap is forced in an axial direction toward the support plate. A spacer of chosen length can be provided to set preload on the spring. In a "flippable" embodiment, the mounting member includes a mid-portion snap-fitted to the support plate and upper and lower portions each having a sliding cap associated therewith, wherein the spring acts between the two sliding caps. In yet another embodiment, the sliding cap is replaced by a bellows attached to the mounting member.
