To calculate the overall star rating and percentage breakdown by star, we do not 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.
Usually lazy to write reviews but this product is so good I bought a second one in the end. My dad fractured his ankle so he’s been bed ridden and this has been great in helping him sit up comfortably while in bed. It was well packed and shipped promptly. Would recommend.
