I agree with the others. What's the use in having them not to have them in the car for the style and function? You can always recover them again if you mess them up, right?
I put a towel down on the bottom part of the seat to keep from wearing out the upholstery, looks kinda corny but it works, also an old T shirt over the back, if you want to show them off just pull the T shirt off and toss the towel in the back.
