If you have a child who is on the spectrum or has Sensory Processing Disorder, your OT may have suggested an astronaut board. I have to admit I had no idea what this was before I googled it. I found a few sites selling them but they can be expensive (about $130), so I was happy when I came across this site that has instruction to make your own for a fraction of the cost.
I am changing mine up a little. First, I'm using natural hardwoods to make sure I'm limiting the chemicals in the wood. I'm also rounded my corners and sanding them so I don't have any sharp corners. And I'm going to add more padding for added comfort and safety. I can't wait to finish it!
