1. A controlled sleeping surface, comprising:
a memory for storing a precalculated user-specific optimal sleep rhythm that specifies an optimal sequence of sleep states that are optimal for a specific user based on one or more user characteristics of the user, the user characteristics comprising the user's age, gender, weight, and height, wherein the optimal sequence of sleep states further includes a time period that the specific user should be in each sleep state of the sequence of sleep states to yield optimal sleep for the specific user;
a processor implementing an identity determiner to determine an identity of a user on the controlled sleeping surface based on sensors of the controlled sleeping surface and to obtain the precalculated user-specific optimal sleep rhythm of the user from the memory for the identified user;
a monitoring system to determine an actual sleep state of the user on the controlled sleeping surface;
sleep phase logic to determine a current optimal sleep state of the user on the controlled sleeping surface based on the actual sleep state of the user, the precalculated user-specific optimal sleep rhythm of the user, and a period of time that the user has been in the actual sleep state; and
a controller to adjust a firmness of the controlled sleeping surface based on the determined current optimal sleep state of the user, the controller further to adjust a temperature of the controlled sleeping surface based on the current optimal sleep state of the user.
