Title: Aquatic mat
Claims: What is claimed is: 1. An aquatic floatation mat capable of floating in water and supporting one or more persons, comprising an elongated planar member having top and bottom planar surfaces and a headrest secured to and extending from an end portion of said planar member; said planar member and said headrest formed from closed cell, unicellular, plastic foam slab members, which are flexible, resilient and non-water absorbent, and which have a surface coating of a tough, pliable, plastic material; said headrest slab member having ends thereof secured to an end portion of said planar member, said headrest has a generally rounded shape and includes one open transverse void above said top planar surface. 2. The aquatic mat of claim 1 wherein said headrest slab member is curved around an end portion of said planar member, the ends of said headrest are secured to the top and bottom planar surfaces at an intermediate portion near the said end portion of said planar member, and the end edge of said planar member is secured to an inner surface of said surved headrest slab member thereby forming two transverse voids, wherein one void is above said top planar surface and one void is below said bottom planar surface of said planar member. 3. The aquatic mat of claim 1 wherein said headrest comprises a curved slab member on each said top and bottom planar surface at said end portion of said planar member, one end of each said respective slab member secured to the said end portion of said respective planar surface and the other end of each said respective slab member secured to an intermediate portion of said respective planar surface near said end portion thereby forming two transverse voids, wherein one void is above and one void is below said planar member. 4. The aquatic mat of claim 1 wherein said headrest comprises one curved slab member on said top planar surface of said planar member, one end of said slab member secured to the end portion of said top planar surface and the other end secured to an intermediate portion of said top planar surface near said end portion thereby forming one transverse void above said top planar surface. 5. The aquatic mat of claim 4 wherein said headrest comprises end members enclosing said transverse void to form an air chamber, and vent holes disposed through said planar member communicating with said air chamber. 6. The aquatic mat of claim 1 wherein said headrest comprises one curved slab member on said top planar surface of said planar member, one end of said slab member secured to the end edge of said planar member and the other end secured to an intermediate portion of said top planar surface near said end portion thereby forming one transverse void above said top planar surface. 7. The aquatic mat of claim 1 wherein said plastic foam is produced from polyvinylchloride. 8. The aquatic mat of claim 1 wherein said plastic coating material is firmly adherent to said plastic foam. 9. The aquatic mat of claim 1 wherein said plastic coating is a sprayed coating. 10. The aquatic mat of claim 1 wherein said plastic coating is a dipped coating. 11. The aquatic mat of claim 1 wherein said headrest comprises end members enclosing said transverse voids to form an air chamber. 12. The aquatic mat of claim 11 wherein said headrest has an enclosed transverse void disposed below the bottom planar surface comprising vent holes in the bottom portion of said headrest communicating with said enclosed air chamber.
