Abstract: A bed system includes microclimate control capabilities for providing quality sleep experience. The bed system can include a microclimate control subsystem configured to supply conditioned air (e.g., heated or cooled air) to a mattress, or draw ambient air from the mattress, to achieve a desired temperature at the top of the mattress. Utilizing supply of conditioned air to provide air at desired temperature to the mattress system, or utilizing air suction to drain heat away from the mattress system, can provide precise microclimate control at the mattress, thereby permitting conformable sleep.

Abstract: A sleep system can introduce outside stimulus such as simulated heartbeat and/or respiration to induce a response from the sleeper which can cause the sleeper's body to mimic or mate up with the delivered heartbeat and/or respiration sequence. Simulated heartbeat and/or respiration introduced to the person's sleeping environment can guide the person from an awake state to a sleeping state, help the person transition between sleep stages, help the person maintain one or more sleep stages for longer or shorter durations, and gently guide the person from an asleep state to an awake state. The simulated heartbeat and/or respiration can also improve the quality of sleep that the person experiences in a given sleep phase.

Abstract: Described herein are mattresses with localized air chamber support. A mattress can include a first air chamber positioned at a shoulder region, a second air chamber positioned at a hip region and fluidly connected to the first air chamber, and a foam insert positioned between the air chambers. The air chambers can share a common internal pressure. Decreasing the common internal pressure in the air chambers can cause the foam insert to increase support at a lumbar region of the mattress. Additional foam inserts can be positioned between at least one of the first air chamber and a head end of the mattress, the first and second air chambers, and the second air chamber and a foot end of the mattress. The mattress can also include a foam rail structure that extends around a perimeter of the mattress to surround the components therein.

A mattress can include a first air chamber, a second air chamber stacked beneath the first air chamber and fluidly connected to the first air chamber, and a support stacked beneath the first air chamber and positioned between the second air chamber and a foot end of the mattress. The first air chamber can extend across a length of the mattress from a head end to the foot end of the mattress. The second air chamber can be positioned at a shoulder region of the mattress. The first and second air chambers can have a common internal pressure, such that decreasing the pressure in the first and second air chambers cause the support stacked beneath the first air chamber and positioned between the second air chamber and the foot end of the mattress to increase support at a lumbar region of the mattress.
