To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I used this on a window seat cushion and am so happy with the results, it lays flat and smooth, was super easy to see in place. I also really like the pulls this comes with. Looking forward to using the rest of my zipper length on pillows for my window seat.
