I had an experienced handyman attach the wheels, and even he was confused since the instructions are poor. So allow yourself some extra time to assemble the wheels. However, once attached and placed upright, the wheels are smooth and its very easy to position. And it folds up into a small footprint just as advertised. Looks great. No issues with quality.
