It's nice to see someone trying to make stuff in the US. Maybe you should market aggressively to schools and art studios? I don't know. I hope that even if you aren't super successful with this effort you keep at it and keep inventing. I think eventually you'll come up with something great!
Here are my issues:
1. It's just ugly. To my eye it looks too American Industrial floor shop item vs kindergarden furniture. I think it's a great idea, but it ain't sleek lookin. The metal base one is better. It needs to look more "IKEA"
2. The video. Not sleek either. It's sad, but slickness sells and you're commercial ain't slick enough. Get one of your artsy fartsy gay film friends to go over it with you and remake parts of the video. You sound like you're from NY so you probably know someone who knows someone.
Just my 1 cent.
Also, I think if you find a market for this thing, maybe it would be like in a university art studio. Maybe you can send a flyer to every university head of the art dept in the world and get some response? Just a thought.
