I have a 20 plate Scala, and for a while now I've found I'm forever adjusting the seat back and height adjustment to get comfortable.
I previously thought it was just me preferring a different position, however this morning I've found this not to be true.
I set the seat to the position I liked and aligned two markers, and then sat in the seat and gently rocked back and forwards for a minute. The adjuster had rotated backwards. (I'll be trying this in the dealership with their car when I'm there too)
I adjusted the seat back four times in a two hour journey, and had to raise the seat a little too.
I'll be in contact with the dealership today. I'm in the fortunate position that I work in vehicle safety testing for a west midlands automotive manufacturer, so I know the seat requirements pretty well.
The first aim is to have a courtesy car until the seats are fixed - which would be a new set of row 1 seats (the passenger side does the same, but not as bad).
If a new set of seats does the same, I'll be aiming for Skoda to retrofit electric adjusting seats to my car; swap the vehicle for one with electric seats; or buy back my vehicle.
Depending on how I get on, it will be taken up with the Motor Ombudsman if I'm not satisfied with the resolution.
NB. Having a quick look in this forum it seems to be a common issue across car-lines, so I doubt a new set of seats will fix the issue.
