Gibraltar 4608 Drum Throne Round

The product itself is of good quality. At least so far. But the locking system is not great, if you put a heavier weight, perhaps an heavier child, or a case like mine, where an adult also sits on it, to give examples during the training exercises.
It ends up loosing tension and not holding the vertical position/setting. But one can surpass that, by moving an addition clamp that limits the vertical movement. It is just not much practical. A threaded system is better, as the ones used in the units oriented for heavier demands.
Otherwise, all is good.
