FWIW, I installed some Wet Okole seat covers in my 2016 Tacoma. Cost new was around $700-800. I installed them myself and they were not difficult to do at all.
The fit on them is really great. The front seats are near perfect, and the rear is very close, there is only one small spot on either side the bugs me, but I might just need to make some adjustments with the straps to alleviate it.
They are neoprene, padded with foam, and you can choose all sorts of options. I added map pockets to the back of the front seats and two small pockets on the front edge of the driver seat, for phone and knife. I also added the center console cover. The quality seems really good, the workmanship seems really good, the fit is the best I've ever had. The only drawback for me was the smell, at first....they stunk pretty bad for a while, but it has all but dissipated now.
I bought them in one of their RealTree camo patterns and couldn't be happier with that. It matches my truck color, Quicksand, and hides any potential dirt or stains really well. Here's some pics of the front, couldn't' take pics of the rear seat as it's covered under a dog blanket currently.
