The grooming arm is pretty sturdy. I used it with combination of a table and another arm to hold the dogs legs still. Sorta  I have a very uncooperative 8lb Morkie and Yorkie. Really helps to trim them up. Whole set up paid for it self after 2 groomings. Has a clamp that will attach to most tables. May not hold up to a large dog. I would recommend to small to medium dog owners.
