I got this for my husband because it has a 550 lb weight capacity so I figured it would be pretty durable. When it arrived, I assembled it and sat on it to try it out. One of the wheels immediately broke… and I am nowhere close to 550 lbs!  I tried to return it but amazon referred me to the manufacturer. The link they provided just took me to the sales website. The phone number rang to a message service. I bought my own set of replacement wheels and it’s working out ok now.
