I ended up with an eleven-legged bed, because I had a mountain of soda bottles to get rid of. 9 legs is probably plenty. Each leg is made up of 7 bottles. Make yourself a template by balancing 7 lidless bottles upside down on a piece of paper, and trace around each neck. Put one in each corner, middle of edge, and center of bed, as shown. The extra 2 at the head of the bed as shown here are probably unnecessary and reduce the amount of storage under the bed for suitcases etc.
