A mattress includes a chamber defined by upper and lower panels and a peripheral border all constructed from synthetic polymeric/copolymeric plastic material and housing therein a spring unit. The spring unit includes a plurality of springs having upper ends connected to a peripheral border rod. The spring unit is devoid of a peripheral border rod at lower ends of the springs. Upper edges of the spring unit can be deformably gripped by the upper panel, the peripheral border and/or both to prevent "swimming pool" effect.
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.
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.
The invention relates to a piece of seating and/or reclining furniture, especially a bed, which emits rays of light. In particular, a mattress (10) is provided with illuminants (12) in the mattress core (17) and/or in the cover (18), or between the mattress core (17) and the cover (18). The light irradiation, to which a person (11) is exposed promotes the stimulus for sleeping and/or waking up. The mattress also promotes therapeutic effects, for example wound-healing properties.
