Air circulation and bed-cover suspension unit for a bed

An air circulation unit introduces air into a space under the bed cover from a foot-end of a bed. The air circulation unit includes an assembly for suspending the bed cover so that an occupant or occupants of the bed are partially relieved of the full weight of the bed cover. In use, the unit serves to introduce air which may be heated or cooled or at ambient temperature into the space under the bed cover and so circulate air over the occupant or occupants of the bed to keep the occupant or occupants as comfortable as possible during sleep despite surrounding conditions.
