Bailey wheels have a standard 19" tolerance from the ground to the top of the wheel head. To encourage correct posture for all the different sizes of potters, Bailey has developed the best optional adjustable leg system on the market. This Short Leg Set is practical for variable "higher sit" positions and the wheelhead to be set between 19" and 27" high. Sitting on a higher stool, such as a drafting chair, is far healthier and more comfortable on your back. Each leg set includes hardware. Great for leveling your wheel!
