A suspension member for a seat assembly includes a plurality of zones which define spatially varying properties of the suspension member. Each of the zones produces a response to an occupant load imposed on the seat assembly by a seated occupant, where the response includes one or more of a stiffness response, an energy dissipation response, and a thermal response. The response produced by each zone is different from the response produced from any other of the zones. The suspension member can be made of a homogenous material or made of a combination of materials such that each zone is made of a different material. The suspension member can include a textile material formed by weaving, knitting or crocheting. At least one zone of the suspension member can include one or more apertures.
