I posted a project on Donors Choose with the following description.
Our new items arrived on Monday morning! That's right...Amazon prime shipping is amazing. I went from posting the project to receiving my items in 5 days total. Crazy, right?!? I combined our new stability discs, wobble seats and balance balls with the items I already had. I spent that afternoon rearranging furniture until I made everything work. Click on each picture to see the new item on Amazon.
Here are a few pics from our current new arrangement. I realize this might change as we get more comfortable with our flexible seating. The dice cubes were something I picked up a few years ago at Walmart. The crate seats were made a few years back and the "buddy" bench is a yard sale find from 11 years ago. :)
