Sleep Phase Dependent Pressure Control And Learning Methods To Optimize Sleep Quality
A bed includes components to control pressure of a sleep surface, for example based on sleep position and sleep stages of a user. In some embodiments target pressures for the sleep surface are iteratively adjusted over multiple sleep sessions so to achieve improvements in sleep states and/or sleep quality for the user.

- 1. A bed including a sleep surface having controllable firmness, comprising:
pressure devices used in adjusting thinness of the sleep surface; pressure sensors configured to sense indications of pressure of the sleep surface; and a controller configured to command the pressure devices to target pressures, as indicated by at least one target pressure profile specifying the target pressures; with the controller further configured to, from time-to-time: command the pressure devices to test pressures instead of at least some of the target pressures specified by the at least one target pressure profile; determine if a sleep metric for a sleeper on the sleep surface indicates improved sleep performance using the test pressures instead of the target pressures specified by the at least one target pressure profile; and, in response to determining that the sleep metric for the sleeper indicates improved sleep performance, replace the at least some of the target pressures specified by the at least one target pressure profile with the test pressures.
- 15. A method of conditioning a bed with a sleep surface having controllable firmness, comprising:
commanding pressure devices to target pressures, specified by at least one target pressure profile, with the pressure devices being under the sleep surface of the bed; and from time-to-time: commanding the pressure devices to test pressures instead of the target pressures specified by the at least one target pressure profile; determining if a sleep metric for a sleeper on the sleep surface indicates improved sleep performance using the test pressures instead of the target pressures of the at least one target pressure profile; and in response to determining that the sleep metric for the sleeper indicates improved sleep, replacing the target pressures of the at least one target pressure profile with the test pressures.
