Can anyone explain to me whether it's possible to adjust the front seat once an Axkid Minkid 2 is installed behind it? Or does the front seat have to remain fixed in position once the AM2 is tethered to it? Wondering if it's possible to have it tethered to the driver's seat, which will need constant adjusting as DH and I are very different heights - or will that mean that every time we need to switch drivers the whole seat would need to be uninstalled, driver's seat adjusted, and then seat reinstalled? I can't understand the instructions I've found online.
