US Patent 9474384 Mattress thermal management system

The disclosure generally relates to a mattress thermal management system, for example a mattress cooling and/or heating system and in particular a suction- and/or discharge-based cooling and/or heating system. Deck-mounted fans beneath a mattress operate in various embodiments to induce a uniform suction flow, a uniform discharge flow, and/or a combined suction/discharge (circulating) flow that enhances the cooling and/or heating rate of the mattress. The mattress thermal management system can be incorporated into a conventional mattress/bed system or into an adjustable bed system.
