The Wet Okole seat covers are around 20 years old and still working well, albeit showing some wear on the outer fabric layer. I've been covering them with other seat covers for about 10 years now. I find the snug neoprene cover really helps with the comfort of the lower seat cushion. I also have an inflatable lumbar cushion built into the driver's seat back cover that's still working fine.
