A unitary deflection member. The unitary deflection member can have a fluid pervious reinforcing member and a patterned framework. The patterned framework can have a plurality of regularly spaced protuberances extending from the reinforcing member. At least two of said protuberances can be similar in size and shape, and each protuberance can have a transition portion having a transition portion width and a forming portion having a forming portion width. The transition portion width can be less than the forming portion width. 1a fluid pervious reinforcing member;a patterned framework comprising a plurality of regularly spaced protuberances extending from said reinforcing member, at least two of said protuberances being similar in size and shape;wherein at least two of said protuberances have a stepped, multilevel shape; andwherein said plurality of regularly spaced protuberances are linear segments, the linear segments having a cross-sectional shape, the cross-sectional shape being selected from key-hole-shaped, mushroom-shaped, circular, oval, inverted triangle, T-shaped, inverted L-shaped, egg- or pebble-shaped and combinations thereof..
