The amazon description doesn't say it, but the Coverking catalog that came with the covers says "not the best fit, but the most durable." The first part is true. The later - not so much. The zippered part for the rear bench backrest broke the instant I pulled on the zipper. Looks like the zipper itself was broken on arrival making the zipper malfunction. Also - the design doesn't work with my 2010 Tundra rear bench (which the description clearly states it does). The two flaps that are supposed to Velcro together to secure the bottom of the backrest cannot possibly velcro together because the design of the seat doesn't make it possible (fabric/plastic of the seat runs from the back all the way to the front, there is no access to the back from the "hinge"/bottom of the backrest). Absolutely ZERO instructions in the package. At least a diagram of how the various flaps are supposed to secure around the fold down armrest would be nice. I bought these because I have a dog and wanted to test them before buying the front bench as well. Will return and try another brand. Reviews I've read elsewhere say the denier rips easy too- though 1680 seems higher than most other "denier" type covers I've seen available.Other fitment issues - holes don't line up, cover is baggy, creases or folders across the sides and front.
