The popular Cup Holder Pedestal is about 5" tall.  It features an adjustable flywheel base that expands to fit varying cup holder opening except for those that are so large that the 7-Eleven Big Gulp falls over.  

This is a great solution for those that do not want to drill or loosen seat bolts.  We have lots of other mounts as well as you can see from our store listings.
