A body support structure includes a support frame having at least first and second opposite side portions and defining an opening therebetween. A molded elastomeric member is connected to the first and second side portions and suspended over the opening. The molded elastomeric member includes a mechanical structure decoupling the molded elastomeric member in first and second directions such that the molded elastomeric member has different load bearing characteristics in the first and second directions, wherein the first direction is different than the second direction. A method for forming a load bearing structure is also provided.
