Abstract: 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.

Abstract: A bed includes environmental control components, which may be temperature control components and pressure adjustment components in some embodiments. The environmental control components may be configured to provide different sleep environments based on identity of sleepers using or expected to use the bed. A controller may determine a number of sleepers for the bed, identify the sleepers, and determine if there is an expectation of later arrival of sleeper in determining a configuration for the environmental control components in providing a sleep environment for the bed.
