OK new Sofa bed is about to be ordered......

Looking now before it arrives to get a waterproof/stain proof cover/s so that
the sofa is protected from the 5 mad hounds..
Ideally one that covers the arms and the cushions...

Big bonus if they can come in different colours.

Any ideas of where to look?

Might have what you want? Or there might be someone local to you who's handy with a needle & thread that can craft up exactly what you like.

I was lucky enough to find attractive throws that match my sofas that are washable, I've seen similar in Hhomebase.

If you want waterproof too you could buy a waterproof matress pad, fit that over the seat cushions, and then put your throw on top. 

I got a cover thats waterproof one side and tarten the other, that you sit on for picnics, then brightly coloured throws at £5 a time from Ponden Mills to use over the waterproof one that we wash when hairy!!!!. Dogs who's have em..... and decent furniture.
