US20190336720

1. A bed including a sleep surface having controllable firmness, comprising: (5) (6)

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.

2. The bed of claim 1, wherein the at least some of the target pressures are target pressures of a pre-sleep profile associated with the sleeper. (2) (0)

4. The bed of claim 1, wherein the sleep metric for the sleeper comprises an amount of slow wave sleep. (0)

5. The bed of claim 1, wherein the sleep metric for the sleeper comprises a total sleep time. (0)

6. The bed of claim 1, further comprising biometric sensors configured to provide biometric information regarding the sleeper. (1) (0)

7. The bed of claim 6, wherein the controller is further configured to determine sleep stages of the sleeper based on the biometric information regarding the sleeper. (3) (0)

11. The bed of claim 1, wherein the controller is configured to utilize the test pressures over multiple nights, and to use a statistically calculated value for the sleep metric. (0)

15. A method of conditioning a bed with a sleep surface having controllable firmness, comprising: (6) (5)

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.

16. The method of claim 15, wherein the at least one target pressure profile is associated with the sleeper. (0)

17. The method of claim 15, wherein the at least some of the target pressures are target pressures of a pre-sleep profile associated with the sleeper. (2) (0)

19. The method of claim 15, wherein the sleep metric for the sleeper comprises an amount of slow wave sleep. (0)

20. The method of claim 15, wherein the sleep metric for the sleeper comprises a total sleep time. (0)

21. The method of claim 15, wherein the controller is further configured to determine sleep stages of the sleeper based on the biometric information from biometric sensors. (2) (0)

26. The method of claim 15, wherein the test pressures are utilized over a plurality of sleep sessions, and the sleep metric is a statistically calculated value based on information over the plurality of sleep sessions. (0)
