As a coherent story this chair is terrible. The parents start off saying they couldn't find a good chair for their kids. So they designed a decent looking chair and it seemed like a great idea that it would work for kids until they were about 10 years old. That's a great solution, adult chairs can be pretty bad for kids at the dinner table. Anyway.
Then inexplicably, halfway through the video this crap about measuring the child's weight every time they use the chair. Nothing in the original problem says anything about tracking weight? Ridiculous leap from "can't find a good high chair" to "high chair with built in wireless scales".
Is there something in the kickstarter ts&cs that says "projects must have wireless connectivity and an app" that I'm missing?
