The polyurethane foam is prepared from a polyurethane-forming composition that uses water as a blowing agent and polyol or polyol mixture that has a high functionality and an average hydroxyl equivalent weight of 100-130. The selection of polyols permits cycle times to be reduced by allowing for faster demolding and shortened aging times before post-molding heat lamination steps can be performed.
