A new mattress essentially characterized by its springs are constituted by steel leaf springs in variable number and force, whose leaf springs are mounted on the frame of the bed frame, solidly fixing them at one of their ends and passing the opposite one through a slot made in the crossbar opposite of the frame, in such a way that it is freely sliding in said slot when flexing under the weight of the body that rests on the mattress.
