I have an outdoor bean bag for Spud upstairs which is hose-able and rather funky in bright red, being filled with polystyrene it's also very warm and insulating and molds to the dogs shape. I also have a Danish Design Lounger which has been in use for 10 years now , it is completely water-proof, wipable , but the whole cover also comes off for washing, it's been through incontinent dogs, lots and lots of puppies, and is still in good nick, I put another duvet in it in the winter, Louie used to like it over other beds as although it's well padded it was easy for him to get up from.
I'd like to get one of these, Orvis, but look at the price !!!
