A new proof of the mean field bounds for magnetizations is presented. It applies to any single-component spin system which allows GHS inequality, and to an N-vector model for N ≥ 3, and to an N-solid sphere model for all values of N, provided that the interactions are ferromagnetic and translation invariant.
