Abstract: The disclosed technology provides for improving sleep quality of a user by adjusting a sleep environment. A bed system can include, for example, a controller that can retrieve, from a data repository, data for a set of past sleep sessions of a user, identify, based on the data, a past sleep session in the set of past sleep sessions that satisfies sleep quality criteria, determine thermal settings for the bed system based on the data associated with the identified past sleep session of the user, and apply the thermal settings to the bed system for execution during at least one subsequent sleep session of the user.

Abstract: A bed has a mattress. One or more temperature sensors are used, each sensor configured to: sense a temperature for the sleeper; and transmit, to a controller, temperature readings; one or more pressure sensors, each pressure sensor configured to: sense a pressure applied to the mattress by the sleeper; and transmit, to a controller, pressure readings. A controller may include a processor and memory, the controller configured to: receive, from the temperature sensors, the temperature readings; determine a skin temperature for the sleeper based on the temperature readings; receive, from the pressure sensors, the pressure readings; determine at least one cardiac parameter for the sleeper; and determine, from the skin temperature and the cardiac parameter, a core temperature for the sleeper that is different than the skin temperature and represents thermal state of a core of a body of the sleeper.
