Thanks for your interest in American Girl dolls!

I don't know the answer to this one, but I suggest that you come to our new location to ask the members what they think. See the stickies at the top of this page for instructions on how to do that.

To answer one part of your question, I believe that the bottom is wood or pressed-board.

Since this board is closed, I am now locking this thread.

Best wishes,
Joy
