I would give them 5 stars if the skates didn't wobble. You don't have to push the cart really fast for them to really wobble like an "L". It doesn't matter whether the trolley is loaded or not. I solved the problem by attaching the front of the mounting plate with a 1/8" flat washer. This greatly reduced the problem. I can't say they are all the same as the pair I received, hence your upholstery requirements may be different.
