In a deflection member comprising a framework having a web-side, a backside defining an X-Y plane, and a Z-direction perpendicular to the X-Y plane, the framework comprises a multi-layer structure formed by at least two layers joined together in a face-to-face relationship. Each of the layers has a deflection conduit portion extending in the Z-direction. The deflection conduit portion of at least one layer is fluid-permeable and positioned such that portions of that layer comprise a plurality of suspended portions elevated in the Z-direction from the X-Y plane to form void spaces between the X-Y plane and the suspended portions. The deflection member can comprise a reinforcing element positioned between the web-side and at least a portion of the backside of the framework. Each of the layers can comprise a substantially continuous network, a semi-continuous network, or a plurality of discrete protuberances. A process for making the deflection member comprises the steps of forming each of the layers and then joining the layers together in a face-to-face relationship such that portions of one layer corresponding to the other layer's deflection conduit portion. Each of the layers can be formed by selectively curing a coating of a curable material through the mask comprising a pattern of transparent and opaque regions, and then removing the uncured material. The opaque regions can comprise regions having differential opacities and regions having gradient opacities. The mask can also comprise a three-dimensional topography.
