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.
Good product for the price - it's sturdy in the sense that someone overweight can sit on it with no problem at all. But the rubber coverings on the legs aren't stuck on and three fell off and bounced away while moving it for the first time (down the street - couldn't retrieve them and now the legs can scratch any wooden floors!)
