Bed Part Name, What do you call it in English? Hello Everybody, I am trying to translate a text into English and there is an item that I don't know what to call. It is the base of the bed, but that contains wheels. Here is an image of what I mean. http://www.todomercado.com/tm/aviso/img_avisos/1324078947045_1324079318187_pvaldessara.jpg Do you think I can get away with "wheeled bed frame" or something like "wheeled bed base"? Any suggestions? I would appreciate your help. Thanks in advance! Marco
