I used this to support a compact dryer/washer stack of 280 lbs. total. I left the stack on the castors for a few hours and the corners supporting the weight of the appliance where bent downwards due to the weight. Then, when the base legs were used to support the weight, a similar thing happened after several times of operating the appliances. I was not even using the whole span allowed which would make it even worse.The manufacturer would be better off making metal corners.
