A bedding element including a first large principal face opposite a second large principal face and divided lengthwise into portions that define. on the first large principal face, first successive receiving areas (A1 to A7) of which a first succession (A1 to A7) defines a first resting area and of which a second succession (A7 to A1) opposite the first defines a second resting area; and on the second large principal face, second successive receiving areas (B1 to B7) of which a first succession (B1 to B7) defines a third resting area and of which a second succession (B7 to B1) opposite the first defines a fourth resting area. The portions of the bedding element that define these receiving areas have differentiated mechanical characteristics so that the four resting areas have four different receiving profiles.
