The bed is supported above a plenum chamber arranged to be supplied with conditioning medium being supplied from means comprising an inlet duct for conditioning medium under pressure, said inlet duct communicating with a first and second duct each communicating with said plenum chamber, heating means provided in said first duct, and bleed-off means associated with at least one of said first and second ducts whereby the relative proportions of heated and unheated conditioning medium entering the plenum chamber can be adjusted.
