1. A spring module for an adjustable sleeping system, comprising:
a spring rail that defines a length, a width, an upper surface, and a lower surface, the spring rail having a plurality of apertures extending between the upper surface and the lower surface along the length;
a plurality of adjustable spring assemblies spaced along the length of the spring rail;
each adjustable spring assembly comprises:
a motor with a stator and a rotor, the motor coupled to the spring rail within one of the plurality of apertures;
a lead screw coupled to the rotor and extending above the upper surface;
a spring plate coupled to the lead screw for translation along the lead screw away from the spring rail in response to rotation of the lead screw in a first direction and for translation along the lead screw toward the spring rail in response to rotation of the lead screw in a second direction opposite the first direction; and
a main spring having a first end coupled to the spring plate, the main spring extending away from the spring plate to a second end opposite the first end, wherein the main spring is configured to be compressed in response to the spring plate translating along the lead screw away from the spring rail, and to be de-compressed in response to the spring plate translating along the lead screw toward the spring rail.
