We love our covers! We bought expensive, new furniture...then got a puppy 2 months later. We suffered through blankets to protect the furniture, but then found Nolan! So comfortable, fits all shapes! The company says the back cushion covers do not work if they are attached. They work great for us. Our pup banks off the back, and sits on the top, of our sofa. The covers never come off. She chews her bones on it...just a quick soap and water sponge, back to just like new! I will be ordering anoth...
