The grain filling is provided as a cushion or similar insert (6, 7) and which is removable by an opening from the gap. The interior material and the external material consist of a washable textile material. The opening is closed by a catch mechanism (2, 3) such as a zip, a hook-and-loop fastener or a button fastener.
