ABSTRACT:
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.
