I love the slip cover but not the customer service. 
I received the slip cover today and immediately went to order five more (I had ordered only one just to make sure it would fit) but the price had increased by $12.00ea. I contacted Wayfair immediately but they said there was nothing they could do. I guess I should have ordered all 6 of them and then returned them if they didn't fit. Thought I was doing the right thing.
