One more Earth Day-themed post just fell in my lap. A few weeks ago, an architect friend told us about the me too! Portable Chair, which they loved. It turns out to be the most expensive of the three brackets-on-the-table-edge style portable chairs we considered, but it was the best-designed with the least materials. Very form follows function.
The me too! is contructed like a piece of climbing equipment, with a trim, lightweight nylon seat and milled aluminum hardware. The hefty, square brackets look awesome but heavy; if they were smaller, this thing would weigh nothing at all. [Of course, the clamps that support your firstborn child are the one place you probably don't want to start compromising on, so I'll deal with it. They're still much better than the competition.]
So what's the Earth Day hook, you ask? The me too! folks have kids, too, and they want "to make sure the world we leave them is as good or better than the one we inherited. So when your last child has outgrown the me too! seat, just send it back and we'll recycle the aluminum." Of course, if you recycle it on ebay, you'll have more to leave for your own kid's inheritance, too.
