We have an incoming Three, and I'm looking for suggestions for a slippery, (preferably waterproof) seat cover for the passenger seat. My wife transfers from a wheelchair and I'd like to find a fitted, slippery cover to make it easier to position her in the seat. Only the seat bottom needs to be covered and I'd prefer something removable. I know I could have gone with a Four with leather, but I don't like driving on uncooled leather seats. Thanks for your suggestions.
Regardless of what seat covers you get, applying a leather conditioner such as Zaino Z-10 Leather in a Bottle on a regular basis will make it far more slippery than otherwise.
