I had the factory Nissan neoprene seat covers in my 2000 Xterra and they lasted for about 14 years. I think that they were made by CoverKing. I replaced the fronts with Wet Okele. That was the worst decision that I ever made. The Okeles started to show wear after about a year. and the seams started to go shortly after.
I put Cover King Neoprene covers on my '14 Xterra since it was new. They have two levels of neoprene covers, these are the bettor of the two. They still look and work as new after three years. I had some sun fading on the passenger seat bottom cover, I called customer service and they replaced the part in a week at no cost to me. I recommend them without reservation.
