A mattress with adjustable hardness comprises at least one resilience supplying module, at least one air bag module and a lining provided for the resilience supplying module and the air bag module to be placed therein. The lining is provided with a plurality of lattice-like units, each lattice-like unit defining a mounting space therein. The resilience supplying module is provided with a plurality of elastic bodies respectively provided in one of the mounting spaces. The air bag module is provided with a plurality of air bag units respectively provided in one of the mounting spaces. In this case, the air bag units may be inflated consistently, and the expanded volume of each of the air bag units after inflation may be limited to be uniform by the corresponding lattice-like unit. Thus, the problem of incapability of being kept evenness after inflation in the conventional practice is solved.
