a seat pad having an outer surface;

a pair of support members embedded within said seat

a net embedded within said seat pad and extending along a substantial portion of said seat pad between said pair of support members, said net including predetermined sections extending along said outer surface and being formed of a heat weldable material; and

a seat cover enveloping a portion of said outer surface, said predetermined sections of said net being welded to said seat cover.

2. The seat assembly as defined in claim 1, wherein said seat cover is also formed of said heat weldable material.

3. The seat assembly as defined in claim 1, further including a plurality of means formed of said heat weldable material for adhering said heat pad to said seat cover, said adhering means being positioned on said seat cover proximate said predetermined sections.

4. The seat assembly as defined in claim 3, wherein said adhering means include a plurality of individual tape sections.

5. The seat assembly as defined in any one of claims 1 through 4, wherein said heat weldable material consists of material weldable by high frequency electric heating selected from a group consisting of nylon, polyester and vinyl chloride.
