Abstract: A shelf (20) for a refrigerated cabinet has a first curved surface or formation (25) on the underside of the shelf (20) adjacent the front (22) of the shelf (20) and a second curved surface or formation (24) on the underside of the shelf (20) adjacent the rear (23) of the shelf (20). The first curved surface or formation (25) is configured so that air flowing along the underside of the shelf (20) towards the front (22) of the shelf (20) is deflected in a generally downward direction. The second curved surface or formation (24) is configured so that air flowing generally upwardly towards the shelf (20) is deflected to flow along the underside of the shelf (20).
