<p>An interlockable foam pad (12) adapted with other interlockable foam pads to form foam pad structures (30, 40), such as a three-dimensional structure (30) or a foam pad exercise mat (40). The foam pad comprises a core foam layer (16) of a polyethylene foam layer, the top and bottom foam layers (14, 18) having a higher density than the polyethylene foam in the core foam layer, and having a thickness considerably less than the thickness of the core foam layer. The foam pad (12) includes at least along one side edge, and typically along a plurality of side edges, a plurality of alternatingly spaced apart uniform male and female sections (20, 22), and which sections are adapted to interlock together with slight hand pressure with the male and female sections of an adjacent foam pad. The interlockable foam pad, which is a very low density of the core foam layer, and the higher density of the top and bottom of the foam layer, permits the employment of very light pressure, such as pressure exerted by a child, to provide for the interlocking of the male and female sections to form a foam pad structure.</p> |
