Car seat covers that don't stretch the leather seats?
 

Hoping someone can help me out. I go to the gym everyday and leave sweaty. I'd like to use one of those throw-on car seat covers, but the few that I tried had a leather/sticky backing and would stretch the leather seats from the downward pulling action when I'm sitting.

Any suggestions on a cover that won't stretch my seats?

Not sure about a seat cover, but I give myself a quick sponge bath using a wet gym towel before drying off and putting on some clean 'gym' clothes, usually a t-shirt and lightweight warm-up pants. It's less hassle than showering there and I don't have to worry about my seats.

Are Aston Martin seats prone to excessive wear? I've noticed many late model low mileage cars for sale who's driver side seat bolsters look like they have 50k miles of wear and the seat bottoms very stretched.

Bolsters don't hold up terribly well. Pretty common on most Aston seats I've seen - probably due to how soft the leather is with those being high-abrasion areas (they get rubbed every time you get in and out of the car).

I simply bring a change of clothes and change into them for my ride home.
