I faced the same replacement issue on our 2014 SR5 (cloth seats) and on my 2005 Honda Accord (leather seats). While researching the Honda, I found ridiescom on e-bay. Inquired if the they would do Honda seats and they replied back:
Sorry, we don't have the pattern for your seats. If you are willing to send us your old seat covers then we can make the pattern out of it, but it will take about 2 months for you to get new ones. And please know that you will not get your old seat covers back.
If you are interested, then please know, and the 2 front seat covers in genuine leather will be $550 and in nappa leather will be $700.
That’s a very decent price for leather seats. I don’t always use the car as I ride a train to work in LA. I had bought cheapo Chinese seat covers which go over the existing leather. They looked good in the pics, but they slide all over the place. The real challenge is finding replacement foam, but I’m told that shops can make those.
