My husband uses this product around the kitchen and to transport meals, newspapers, and other items from room to room.  He has Parkinson's and has balance problems, so he loads up the cart - pushes the cart ahead a step, then is free to worry about walking without carrying anything.  Pushes the cart another step, walks again.  That is why sturdier wheels would be good for us, if we just used it in the kitchen it would be fine.  I enjoy using it in the kitchen area if he isn't in need of it.
