a main portion having a front, rear, and lateral sides; and
a support portion at least partly within the main portion such that it is centrally located between the lateral sides of the main portion, the support portion being more resistant to deformation than the main portion and including:
a core portion of substantially uniform vertical thickness that is centrally located between the lateral sides of the main portion and which extends towards the lateral sides of the main portion to a width for supporting the ischial tuberosities of a user;
lateral peripheral portions which extend laterally from the core portion toward the lateral sides of the main portion, the lateral peripheral portions tapering in vertical thickness from the core portion in a direction toward the lateral sides of the main portion; and
a forward peripheral portion which extends forwardly from the core portion toward the front side of the main portion, the forward peripheral portion tapering in vertical thickness from the core portion in the direction toward the front side of the main portion,

wherein the support portion includes a top surface and a base surface substantially parallel thereto, the top surface having a greater area than the base surface such that it extends beyond the base surface at the forward and lateral peripheral portions, and, at each of the forward and lateral peripheral portions, a sloping wall extends from the base surface to meet the top surface, and
wherein the sloping wall at the forward peripheral portion slopes at a steeper angle to meet the top surface than the sloping walls at the lateral peripheral portions.
