Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
Not true to size, shows picture over a double bed and sofa. My son has a single bed and its not even the length of his headboard. Doesn't stick, when left for any length of time, comes away from wall and curls up. Very disappointed. Wouldn't purchase again
