I received it as a gift and installed it in RedHot. It has two coated bendable metal fingers that go under the rear carpeting and secures it. Once you install it you don't need to fuss with those again. It rolls up and secures with Velcro straps, out of the way of the sub-woofer. I like it and use it when I put in or remove my golf clubs so there is zero concern about scratching any part of the car. Other than when I use it for that it is out of the way and doesn't really take up hardly any trunk space. So bottom line, if you put bulky things into your trunk with some frequency I would recommend it.
