The chair wipe is an at-home drill designed to help you feel the direction of the wipe movement as you start your release. Many golfers who struggle with shaft lean at impact benefit from doing wipe training at some point in their swing building phase. This simple addition of using a chair can help elevate the feel your brain gets from wipe drills. That additional feel can often be enough to help give you that elusive eureka moment and move the wipe into one of your shaft lean keys.
