I saw the slide pictured in the following link at a Gymboree Play & Music. I could not find any manufacturer name on this molded plastic slide. The Gymboree staff person did not know where it came from.
Does anyone know of a source for it?
Do a google image search for "circle Slide." THere is a picture of one in a picture inventory. If you contact them, they should be able to tell you who makes it.
Here is a link that might be useful: Nautilus slide from Learning Products
