In our old Superb from 2011 with leather seats we had a rear cupholder in the foldable armrest. Our new 2015 with "normal" seats does not have one in the armrest.

 

What have you guys to fix that problem?

There are two cupholders in my rear centre arm rest along with the mounting hole for the optional tablet holder.

 

Fold forward flap A to reveal the cupholders B.

 

Ours looks like this:

 

Well at least you have a strap to pull it down which is more than I have!

Time to get the power drill out? 

I wondered (when we had the fabric seats in the Mk2 Superb) how easy it was to retro fit a rear arm rest to the back seat.
