An athletic mat is made up of uniform plastic foam slabs that are coated with plastic on each face and covered with adhesive along their edges. A mat of the desired shape and color is then assembled by abutting adhesive coated edges of selected slabs to bond together the foam; and the plastic coatings on each face of the bonded slabs are heated, and a heated plastic tape is pressed against the heated coatings to form a fused union between the tape and the coatings on each face of the slabs. The top and bottom coatings along the peripheral edges of the mat are heated, and a heated edge tape is formed into a channel shape and pressed over the peripheral edges and against the heated plastic coatings to form a fused union between the edge tape and the plastic coatings.
