A mattress has at least one inflatable top layer made up of a plurality of adjacent elements that are secured together and that are individually inflatable by a pneumatic inflation and pressure regulation device and at least one bottom layer supporting the top layer. The bottom layer is provided with a recess for receiving a sensor connected to the pneumatic inflation and pressure regulation device, and making it possible to determine the pressure applied by the body of an individual bearing against the inflatable top layer and to regulate the inflation pressures of the elements of the top layer correspondingly, in order to facilitate desired penetration of the body on the device. In at least one support zone designed to support the sacrum of an individual, the top layer is made up of a plurality of inflatable elements that are of a width smaller than their height, the width of said individualized inflatable elements of this zone being smaller than the width of the inflatable elements of an end zone adjacent to the sacrum support zone.
