Abstract
Convoluted foam layers for mattresses, cushions and the like include at least one convoluted surface including at least one convolution that is structurally heterogeneous. The convoluted foam layer is formed of at least two foam layers fixedly attached to one another, wherein the foam layers are of different materials and/or have different properties. Also disclosed are processes for forming the convoluted foam layer and convoluted foam layers having multiple zones of a convoluted surface pattern that includes at least one convolution that is structurally heterogeneous.
