The foam core has a top surface, a bottom surface, and a peripheral side surface. The upper skin covers both of the top surface and the peripheral side surface of the foam core, but extending not beyond the bottom surface of the foam core. And, the lower skin covers both of the bottom surface of the foam core and a peripheral end surface of the upper skin. ## Claims ### Claim 1 A foam product, comprising: a foam core having a top surface, a bottom surface and a peripheral side surface; an upper foam layer covering the top surface of the foam core and at least a portion of the peripheral side surface of the foam core, but extending not beyond the bottom surface of the foam core, wherein the upper foam layer has an inner surface bonded to the top surface and the peripheral side surface of the foam core, an outer surface, and a peripheral end surface; and a compressed lower foam layer made of EPE or EPP and covering both of the bottom surface of the foam core and the peripheral end surface of the upper foam layer, and having an inner surface, an outer surface, and a peripheral end surface, wherein the inner surface of the compressed lower foam layer is bonded to the bottom surface of the foam core and the peripheral end surface of the upper foam layer; a non-foam plastic plate made of polyethylene and covering the outer surface of the compressed lower foam layer so that the compressed lower foam layer is disposed in between the foam core and the non-foam plastic plate, wherein the compressed lower foam layer is compressed and therefore having a thickness smaller than each of the non-foam plastic plate and the upper foam layer. ### Claim 2 (depends on 1) The foam product as recited in claim 1, wherein the compressed lower foam layer covers the whole peripheral end surface of the upper foam layer. ### Claim 3 (depends on 1) The foam product as recited in claim 1, further comprising a sealing member, wherein the peripheral end surface of the upper foam layer is partly covered by the compressed lower foam layer, and the sealing member is filled in a gap between the peripheral end surface of the compressed lower foam layer and an uncovered portion of the peripheral end surface of the upper foam layer, wherein the peripheral end surface of the compressed lower foam layer has no contact with the uncovered portion of the peripheral end surface of the upper foam layer so that the gap is formed between the peripheral end surface and the uncovered portion. ### Claim 4 (depends on 1) The foam product as recited in claim 1, further comprising a plastic film covering the outer surface of the upper foam layer so that the upper foam layer is disposed in between the foam core and the plastic film, wherein the upper foam layer has in its inner surface a plurality of concave dents adjoined to one another; the foam core has on its top surface a plurality of convex bumps adjoined to one another; and each of the convex bumps of the foam core is bonded in a respective one of the concave dents of the upper foam layer. ### Claim 5 (depends on 4) The foam product as recited in claim 4, wherein the bottom surface of the foam core is relatively flatter than the top surface of the foam core, and the inner surface of the compressed lower foam layer is relative flatter than the inner surface of the upper foam layer. ### Claim 6 A foam product, comprising: a foam core having a top surface, a bottom surface and a peripheral side surface; an upper foam layer covering both of the top surface and an upper area of the peripheral side surface of the foam core, and having an inner surface and an outer surface, wherein the inner surface of the upper foam layer is bonded to the top surface and the upper area of the peripheral side surface of the foam core; and a compressed lower foam layer made of EPE or EPP and covering both of the bottom surface of the foam core and a lower area of the peripheral side surface of the foam core, and having an inner surface and an outer surface, wherein the inner surface of the compressed lower foam layer is bonded to the bottom surface and the lower area of the peripheral side surface of the foam core; and the upper and compressed lower foam layers are partly overlapped at the peripheral side surface of the foam core; and a non-foam plastic plate made of polyethylene and covering the outer surface of the compressed lower foam layer so that the compressed lower foam layer is disposed in between the foam core and the non-foam plastic plate, wherein the compressed lower foam layer is compressed and therefore having a thickness smaller than each of the non-foam plastic plate and the upper foam layer. ### Claim 7 (depends on 6) The foam product as recited in claim 6, wherein the compressed lower foam layer is laid on top of the upper foam layer. ### Claim 8 (depends on 6) The foam product as recited in claim 6, wherein the upper foam layer has an end portion overlapped with the compressed lower foam layer; the end portion of the upper foam layer is thinner than the rest portion of the upper foam layer; the compressed lower foam layer has an end portion overlapped with the upper foam layer; and the end portion of the compressed lower foam layer is thinner than the rest portion of the compressed lower foam layer. ### Claim 9 (depends on 6) The foam product as recited in claim 6, wherein the upper foam layer has an end portion overlapped with the compressed lower foam layer; the upper foam layer is formed on its outer surface a plurality of protrusions and concaves staggered from one another, except that the overlapped, end portion of the upper foam layer is substantially flat and smooth. ### Claim 10 (depends on 6) The foam product as recited in claim 6, further comprising a plastic film covering the outer surface of the upper foam layer so that the upper foam layer is disposed in between the foam core and the plastic film, wherein the upper foam layer has in its inner surface a plurality of concave dents adjoined to one another, the foam core has on its outer surface a plurality of convex bumps adjoined to one another, and each of the convex bumps of the foam core is bonded in a respective one of the concave dents of the upper foam layer. ### Claim 11 (depends on 10) The foam product as recited in claim 10, wherein the bottom surface of the foam core is relatively flatter than the top surface of the foam core; and the inner surface of the compressed lower foam layer is relative flatter than the inner surface of the upper foam layer.
