Free Standing Legs allows your reformer to free-stand. This is ideal for multi-function Pilates studio where you need to stand your reformer up out of the way so you can use the floor space. Warning when standing your reformer: Your reformer should only be stood up in places where there is no risk of it being knocked over by other activities in the same room. Never stand a reformer in a room that can be accessed by children. The reformer must only be stood up indoors on firm, flat surfaces.
