First I tried to make a “prototype” and then a longer and more definitive example with a cover. I used an old thin camping mattress, so it is light and flexible stuff. Now I have to  make the definitive version which follows the form between quest bottom and side better (it’s not a sharp 90 degrees corner 😉    ).

I wonder how long it takes when I finally make the definitive version……………..

When the cover is closed I can use it as an armrest for my left-arm, while my left hand is in the right position to give the turn-signals. I am usually steering with my right hand.
