Discrete localized structures are found in optical cavities with focusing saturable nonlinearity. Families of both bright and gray solitons exhibit multistability as they develop internal shelves in the pinning region around a Maxwell point. Both saturability and discreteness are required for these solitons to be observable, but they can occur for either zero or finite losses.
