Mystery chair

So we went to the library the other day. Besides books, of course, there's a little sort of toddler play area, in which we duly played. I was fascinated by these amazing wooden chairs, sort of round and slotted and just really cool. They seemed way too cool to be lurking in the library. So I took a picture with my phone (which I can't post, but will later) and came back and Googled, and they're made by Lakeshore. They aren't these, although they are similar.
