Base for a container, the base being made of polymeric material, including a support surface having an outer perimeter defining a first dimension along a major axis and a second dimension along a minor axis disposed approximately 90° from the major axis. An inner wall is coupled to the support surface opposite the outer perimeter. A dome projects upwardly from the inner wall and has an initial depth with respect to the support surface. The dome includes a major radius of curvature along the major axis and a minor radius of curvature along the minor axis. The dome is deflectable in response to a differential pressure across the base of at least 3.2 PSI without permanent deformation of the base.
