We need a rug for this area and would like a simple durable non patterned rug. Does it need to fit in front of the sofas or a little under them? We'll be painting the walls next month a creamy offwhite as they're way too gray. And with two cousin dogs and a cat moving in next month for 6-12 months we need a sofa cover. Thank you for any help on both a rug and sofa cover.
