Abstract
A massage ball having a plurality of adjacent foam layers including at least one first density foam layer, at least one second density foam layer and at least one third density foam layer, and a glue layer between each adjacent foam layer thereby adhering together the plurality of foam layers. A density of the first density foam layer is different from a density of the second density foam layer which is different from a density of the third density foam layer. The massage ball may also include a solid core in the center thereof.
