Abstract
Abstract Rail attachment arrangements for attaching the ends of a sinuous spring band to the rails of a furniture seat frame. The attachment arrangements include clips which facilitate rapid and accurate positioning on a frame rail. The clips can be fastened with little or no stapling or nailing, yet will not pull out. The clips provide rail top and ''''drop rail'''' spring band connections.
