The question that begs to be asked is - what is going to be gained by using seat covers ?, what are they hoping for for ?
Extra cushioning /comfort and seat protection from wear are reasons we use them. I will try and remember to comment more in the morning it's 3am here.
Edit: We had the non premium 2017 PD SR (no heating or cooling) We got custom made sheepskin covers, which do negate the need for heating and cooling to be used and do add some extra comfort/padding to the seats.
Our previous car to that was a 2014 Holden Calai V which had heated seats. There was a warning about possible overheating when used with seat covers so we no longer used that function when we added Sheepskin seat covers to those seats.
Obviously cooling would also be compromised depending on the type of cover chosen, but at least the cooling funtion wouldn't cause any damage to the cover or seat when covered.
