Some of them do, yes. In our desire to bring the relaxing beauty of rustic decor possibilities to a wide range of shoppers, we have added metal framed log beds to our huge line up of rustic bedroom furniture. You will find these on both lower priced log beds and more exotic priced beds.
Many of the log beds with metal frames will have log or log sections that cover them. This will give you the strength of a metal frame with the look of a log frame.
