Abstract: An air distribution unit for environmentally controlled furniture, such as a bed. In representative embodiments, the air distribution unit includes a fan enclosure for accommodating a fan, with a fan enclosure inlet upstream of the fan and a fan enclosure outlet downstream of the fan, the fan enclosure including an air-flow guidance member positioned in the fan enclosure, which defines at least in part, an air-flow path between the fan enclosure inlet and the fan enclosure outlet, wherein an inner surface of the air-flow guidance member, adjacent to the air-flow path, is at least partially sound-absorbing.

Abstract: Upholstery support arrangements for conditioned furniture are disclosed herein. A representative arrangement, such as for a ventilated bed, comprises an upholstery support structure having a support platform that defines a support plane, for supporting an upholstery item, the upholstery support platform having a first array of apertures that allow a flow of air through the support platform; the upholstery supported on the support platform (e.g., a mattress) having a bottom face facing the support platform and including a second array of apertures positioned to allow the flow of air through the bottom face into the upholstery; wherein a periodicity of the first array of apertures and a periodicity of the second array of apertures are matched to one another.
