The worst thing there is. 100 times better a big sheet. For indoor use and for a porch it's OK (as long as you put something soft underneath, like padding). Not for outdoor use.
Be careful with the placement because it tears with the slightest touch.

The worst hood I ever bought. Money wasted. The first time it ripped on the seam within a month. Luckily, the store where I bought it agreed to replace it and they were indeed impeccable and very helpful. The second hood I received also ripped in the first strong wind. Specifically, it was tied with the strap it has and it completely came off around the car. I regret buying it.
