Sofa bed, double (Helton CA10)

Sofa bed, 2 seater sofa folds out to double bed, covered in beautiful Liberty fabric. Includes 2 matching cusions. Old and much loved, the fabric has finally worn at the front of the sofa, can be covered with a throw or you could use the cushion material to make a patch? Arms have been covered with covers so are in good condition. The mattress is a little stained - see photos.
