DISCLAIMER!!! I have no affiliation with this seatcover maker -- just think his covers are excellent.
We always use seat covers on our cars, and usually, REGARDLESS OF PRICE AND "CUSTOM" CLAIMS, we have to settle for cloth bags that detract from the car's appearance. (BTW, I have owed dozens of cars with leather seats, and if left out of a garage and not protected, the leather breaks down within 7 years or less -- no, I won't spend my weekends "feeding" the leather; heck, I don't even want to waste time mowing the lawn.)
Sometimes we end up with sheepskin covers, but the backside of the sheepskins is typically a rough "cheesecloth" material that actually abrades the underlying leather seats.
So, I decided to try some custom seat covers advertised on EBay for our 06 Cayman S, and I'm pretty impressed with the product.
"Sherif" is the fellow who makes these covers, and when I ordered the covers, he called me up to ask some questions about the fitment.
Turns out he moved here from Paris (France, that is, not TX), and owns 2 Porsches. He had bought seatcovers for his cars and was so disappointed with the product that he figured he could do a much better job. He therefore started making covers for all Porsche models -- and only Porsches (I think he will make them for any model, but only advertises 996/997s, Boxsters and Cayman.)
The covers are some type of canvas outside, with the Porsche embroidered crest on the headrest, and with your choice of colored piping as well. They are lined with a soft material, and they fit tightly WITHOUT using any of the usual series of straps that other covers require to fasten under the bottom cushion. (He uses an elastic drawstring.)
They are side-airbag-friendly, and they feature a side pocket on the console side, which, using the metal slat (included), is used to push the fabric down between the seat and the console.
Some pictures are attached, showing some details, the side pocket, and first fitment in the Cayman. I have to pull them in tighter and align the edges better.
AGAIN, this is an UNSOLICITED description of this product, and I have absolutely no affiliation with Sherif, his family, his business, etc. I don't even know his last name.
Here is a link to one of his ads on EBay: http://www.ebay.com/itm/porsche-seat...918271?vxp=mtr
Sherif's phone number is 305-300-1288, in case you want to ask him to make a set to fit a special Porsche application.
