A base structure (16) for a hot-fill plastic container (10) provides the container (10) with enhanced structural integrity. The base structure (16) uses a series of vertically staggered circumferential ribs (28, 30, 32, 40, 42) interrupted by radial lugs (44). The disclosed base structure (16) enables the container (10) to withstand the various forces encountered in filling, cooling, and handling.
