1. A dressing assembly configured to treat a tissue site, comprising:
a manifold comprising a porous material configured to contract and to distribute a reduced pressure to the tissue site, the manifold further comprising a first side, a second side opposite the first side, and a thickness between the first side and the second side, the second side configured to face the tissue site; and
a reinforcing member coupled at the first side of the manifold and configured to support the first side of the manifold such that the second side of the manifold is configured to contract a greater amount than the first side when the manifold is exposed to the reduced pressure, wherein at least a portion of the reinforcing member is positioned at a periphery of the first side of the manifold.
