We have a Pajero.  We're empty nesters now, and I can't remember when we last used the 3rd-row seats.  .

I could remove them (they're designed to be removable) and store them the attic above the garage.  They weigh around 15kg, so that's some weight/fuel savings right there (I already remove the compressor and second battery).

The only problem is ... it gets hot above the garage.  Steel roof, Marlborough summers etc.  I'm worried what this might do to the leather/foam long term.

But it also gets really hot inside the car, and all the other seats are fine.  So ...  if I condition the leather wrap the seat it in an old woollen blanket and it should be fine?

Any advice welcome.
