1. A method comprising:
receiving data from one or more sleep sensors including an inductive sleep sensor, wherein the inductive sleep sensor comprises at least one fixed coil and a hinged metallic portion, the inductive sleep sensor integrated in a mattress system including a mattress and a solid base, wherein the at least one fixed coil of the inductive sleep sensor is directly attached to the solid base and the inductive sleep sensor measures force placed on the inductive sleep sensor by inductively sensing, by the at least one fixed coil, movement of the hinged metallic portion in a direction perpendicular to a sleep surface of the mattress system;
detecting two or more sleepers using the received data;
analyzing the received data to determine movements of the two or more sleepers on the mattress system, wherein analyzing the received data comprises:
monitoring relative data of the two or more sleepers; and
attributing a portion of the received data to a sleeper of the two or more sleepers using the relative data; and
providing results of the analyzed data to a user's mobile device via a wireless connection, for display to the user.
