A mattress (900) provides a user with three-dimensional firmness zoning, the mattress (900) cooperating with a mattress shell (720). The mattress (900) includes a plurality of longitudinally spaced, transversely extending resilient blocks (910) being independently movable relative to one another, an inflatable bladder (914) positioned to lie upon the top side of at least one of the blocks (910), and a topper (912) positioned to lie upon the inflatable bladder (914), the topper including opposite ends configured for attachment to the shell (720).
