Over the last year I have been designing an inexpensive easy to use front and back seat cup holder for a Model S and X Tesla. Along the way I added a place to hold two cell phones, which is a need often overlooked, and adds significant value and utility. Being able to use the arm rest at the same time while enjoying a cold or hot drink makes the Tesla EXPERIENCE complete. I hope you will try one of our cup holders out as we guarantee your satisfaction. Now in stock and shipping daily.
