Unused Bath/Shower Stool (TN38 St Leonards-on-Sea)

I bought this for my mother-in-law but due to a miscommunication she doesn't want it, so it has never been used. It is supposed to be rust free (aluminium, plastic, rubber and brass parts). There are very slightly darker grey marks on the grey foam cushion but it arrived like that - a quick inspection will confirm it is brand new. It is light but sturdy, 19.5 inches high but can be lowered using the adjustable legs. the seat is 20"w x 12"d, legs are 15" x 13.5" if you include the ferrules. It has handles and a slot for a shower head.
