I bought one for my sofa and another for the love-seat. (Pics show the love-seat.) I'm moving into a smaller house and don't want to bring my nice furniture. As I will be keeping these in storage for the next year, I wanted a way to keep them protected. I feel confident about these covers. They're thick and seem impenetrable to dust, moisture, odors and other possible effects of the "elements." They're super easy to apply, considering how large and awkward the shape is. I would describe the material as equitable to covering with a huge, super thick and durable contractors trash bag, except clear. I plan to tape them shut before transporting.
