Fabric covered Sofa and chair (Maidenhead SL6)

I have loved and used this furniture for years but now have to face replacement as the spring covers are worn and I have support boards underneath the cushions, which in truth work. Either they go to the tip or I find someone whose animals would like a soft bed. I am not offering for human use as they are old and the chair has a tear I cannot mend. But yours (or your pets) if you want anyway. Any ideas bar the tip? Even if it is just for the cushions which are in very good nick.
