A deformable body, wherein the body is constructed from a multiplicity of layers of a polymer construction material and in which a construction direction is defined perpendicular to the layers. The body preferably comprises layers with a multiplicity of curve pairs (10) which are formed by the construction material and which run in the same direction as one another, the curve pairs comprise in each case two periodic curves (20, 30) running oppositely with respect to one another, and the curve pairs comprise portions of maximum spacing to one another (40, 41, 60, 61) and portions of minimum spacing to one another (50, 51, 70, 71). In one part of the layers, in adjacent curve pairs (10), at least one portion of maximum spacing (41) of one curve is connected to a portion of maximum spacing (60) of an adjacent curve, in a further part of the layers, in adjacent curve pairs (10), at least one portion of maximum spacing (41) of one curve is not connected to a portion of maximum spacing (60) of an adjacent curve, in a further part of the layers, in adjacent curve pairs (10), at least a part of the portions of minimum spacing (50, 51) are connected to one another, and in a further part of the layers, in adjacent curve pairs (10), at least a part of the portions of minimum spacing (50, 51) are not connected to one another. The invention also relates to a method for producing the body and to a device for supporting and/or bearing a person having the body according to the invention. The boy may be used inter alia as a mattress or as a vehicle seat.
