Abstract
A method is disclosed for fabricating an anti-fatigue mat that employs a layer of resilient gel material that exhibits a first durometer. The method employs a frame assembly that receives a flexible support sheet. The frame assembly includes an aperture that receives a layer of heated liquid gel which cools to form the layer of resilient gel material exhibiting the first durometer. In one embodiment, a barrier layer exhibiting a second durometer is situated on the gel layer that exhibits the first durometer. In one embodiment, the barrier layer prevents the flow of oils from the gel layer to a flexible base sheet disposed on the barrier layer. In another embodiment, the flexible base sheet may exhibit a second durometer. In either embodiment, the layers exhibiting the first and second durometer cooperate to influence the feel of the mat to the user.
