Once my wood shop got to a point where I could effectively build most anything, I posted that fact on my Facebook. Then my niece saw that and requested this stool for her kids. She sent me a link to a stool designed by The Wood Whisperer that others that some of her friends had already. Once again, I was more than happy to have a project.
I chose to build it out of red oak that was readily available in our local hardware box store. I also made it so that it could break down flat.
By all accounts, it has happily worked out very well for them!
