Brent I agree with you and knowing your families will help avoid landmines like that.
their are also a lot of other creative ways to use seating and/or standing in your classes.
Some really good examples that I have seen besides the video is yoga balls and wiggle while you work. these are perfectly safe for children. It will take you a few years to work on your class and you will reach an equilibrium of seating in your class. I once walked into a first grade class that had no seats in it just stations and students would sit on the rug during whole group instruction and then move to a center of their choice. For my self I have found that a hybrid of seating at desks and sitting on the rug gave students the best of both worlds.
