Abstract 1. A method for manufacturing a multi-density foamed article which comprises the steps of injecting into an enclosed mold cavity a first foamable material into a first section of said mold cavity divided from a second section by a divider means which will not be distorted while substantially simultaneously injecting a second foamable material into the second section while maintaining said first and second foamable materials separated by said divider means, and foaming and curing said first and second foamable materials with said divider means in place, said first and second foamable materials upon curing yielding foamed products differing substantially in physical characteristics.
