If you use a wheeled rollator, this is not for you. My 97 year old mother would lose her balance picking up and moving this. Or she had to put her hands in an awkward position to move it, and keep her balance. The construction was not stable, and after limited use for two weeks, it was out of align and wobbly and unsafe. It also was difficult to close.. Had the staff of her residence not trashed the packaging, we would have returned it. In the meantime, I am looking for the manufacturer's address as she wants to write to them, giving them her insight into the problems, The concept is great, however.
