Abstract
A cushion assembly defining a thickness direction comprises at least one covering layer and a core layer. The core layer comprises a first member and a second member. The covering layer spans continuously across both the first and second members in a direction generally transverse to the thickness direction, and the first member is disposed adjacent a forward area of the cushion assembly. The second member is disposed adjacent a back surface of the first member. The second member has a higher resistance to resilient deformation than the first member, and the first member has a higher resistance to resilient deformation than the at least one covering layer.
