Occupant support and topper assembly with liquid removal and microclimate control capabilities

摘要

One embodiment of a topper assembly for a mattress comprises a liquid permeable cover layer, a liquid transport layer beneath the cover layer that directs liquid transport therethrough in a preferred direction, a liquid impermeable base layer beneath the transport layer, an air mover in fluid communication with the transport layer and a reservoir positioned downstream of the liquid transport layer. Operation of the air mover moves air and liquid through the liquid transport layer in the preferred direction such that the reservoir captures liquid discharged from the liquid transport layer. A related support apparatus comprises a mattress and a condition management assembly atop the mattress. The condition management assembly includes the liquid transport layer, the liquid impermeable base layer, the air mover and the reservoir.
