All I recall about it is that it seems to have zips of some kind running up the inside corners of the legs which didn't make any sense to me. I guess I can look for a manufacturer's name but I think I have had it for ten years or so, so don't really care.
The bird chair looks a little like the Paulin ameoba chair. We have one of those and it is very comfortable though it is the last chair used in the room. I think that is only because the height makes it look less inviting (a problem the bird chair doesn't have).
