A support assembly for a mattress, the support assembly comprising compressible blocks having individual degrees of firmness, and a sleeve defining spaced-apart pockets holding the blocks therein, the sleeve positioning the blocks adjacent one another and the sleeve being composed of a material having a slippery outer surface permitting individual compression of the blocks so that each compressible block moves in a vertical direction independently of adjacent blocks to enable at least two-dimensions of firmness zoning.
