4ft 6 mattress as new +

Hi, I have a Pine King 4ft 6 (Durabeds) mattress as new (used only 1 night). I bought it by mistake (I was meant to buy a 5ft) and the shop did not want it back because there is a very small scratch (please see photo) that we probably made carrying it up the stairs. The mattress: - firm, orthopeadic; - high loft upholstery; - luxury damask cover; - deep hand tufted; - suitable for divan beds, pine or metal bedstead. It is kept in its plastic cover in a non-smoking house. Collection only, Thanks
