I am trying exercise balls for seats this year. I will tell you...they do squeak and it took me some time to adjust to heads bobbing, but I keep telling myself that they are building core strength (that's what the OT told me ;), this is helping them focus... this is good for them... calm down Danielle you can ignore the bobbing. I took pool noodles and taped them together at the ends to create a base for the balls. Without the base I was constantly chasing the balls around after sessions!
