This pad is made from a composition of rubberised horse hair and is very durable. The pad is glued to the squab frame and then needs to be trimmed to follow the outer edge of the frame. The white wadding material is then laid over this edge and softens the edge of the pad before the seat cover is fitted. To aid seat fitting, we recommend cutting a strip off the plastic bag that your seat covers were packed in and lay over the wadding. This will help the seat cover to slide easily over the padding. Please note these are sold individually.
