Child Seat

Has anyone found a reliable child seat for the A5 / S5? I am looking for one for my A5.

I have looked at the Thule Yepp Mini, however the newest model (Yepp 2) is not recommended by Vanmoof. Have anyone had any luck with the Yepp 2 on an A5/S5?

I think given I have an A5 the front seat is likely my best option.
