Similar to a swimming pool blow-up mat

The material is a kind of vinyl rubber and it comes with a patch kit just like a swimming pool lounge mat you'd use to float around the pool. The instructions tell you NOT TO STORE the mat rolled-up for the season, so guess they expect you to leave it laying around all unfurled. STP's new corporate owners have changed the return policy to one year on all products, so I guess it's a matter of if you feel lucky. Well, do ya?
