Folding Stool from Takashi Sato

While looking around the Moco Loco site the other day, I came across this really cool folding stool from designer Takashi Sato. Sato was born in Japan and only recently began showing his wares in Stockholm and Milan. The stool is made from plywood and felt and is collapsible. I'm thinking that this would be great to have around your apartment for those impromptu playdates (that is if you don't have the space for chairs for each tot). You could tuck these away neatly in a closet or under a bed. Not quite sure how much these go for, but it would be cool to find something that looks this cool but is still affordable.
