Polo 9n3 seat fitment

[polo1.9TDI SPORT]

How do all.
Looking to change the front seat in my polo as I need some more support than what mine give, which isn't a lot.
Nearly got some gti seat but missed them.
So the question is would you be bale to fit the following into the polo without too much diy, and if so what would I need to do?
It's just the front seats at the moment , I would get the whole interior and come to sorting e backs at a later date.
Ibiza and Fabian should go straight in, long with a1.
But can I get the leon cupra/fr seats in? Or any golf seats easily or is the car not big enough to fit them, or would a sub frame need to be made? I was told golf mk 4 fit ?

Something like ths

If you are still looking for the gti interior I have a three door full set of seats front and back in mint condition. Open to sensible offers.
