A seat cushion for an office chair or the like, the seat cushion including:
- 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;
- and
- lateral peripheral portions which extend laterally from the core portion toward the lateral sides of the main portion, the peripheral portions having lesser vertical thickness than the core portion so as to provide a different support profile in the seat cushion when compared to core portion.
