The fit is good, but when they ship it it's folded in half. So, when you install it, there's a hump in the middle, it sticks up a bit. But, I put a couple of large paperback books (left over from college days) on it for a week, and the hump went away.
I already have a storage box under the seat, came with my truck, and it's Not Husky. So when I installed this back seat floor mat, model to allow for storage with Husky Liner, it ended up with a 2" gap under the seat between the liner and the box. Not a big deal because the gap is still under the seat, and when sitting back there, your feet don't go that far back, so it still protects. Knowing the gap, I may change the storage box to Husky, as it appears their storage box is larger with more storage.
I prefer these X-ACT CONTOUR over the WEATHERBEATER. They feel so much softer on your feet. I've had another brand (the popular marketed one) of the hard mats, and I feel like you're resting your feet on a tile floor. Soft is the way to go, because they also conform to the floor better.
Overall, very satisfied with it, the feel and the fit, for my 2015 Silverado 2500 HD, Crew Cab.
Fyi - I gave Durability only 4 stars because not sure how long they will last. I'm sure they'll last longer than me remembering about this post in the future. So by then it will be too late to tell you otherwise. Ha!

a must have

UPDATE 2: I emailed Husky's customer service department, and received a very prompt response from one of their design engineers. He explained that the combination of the vinyl flooring and insulation/sound deadening layer was thicker than the floor anchor is long, which had been my concern in using it in my truck. At his recommendation, I installed the floor anchor. It was a quick, simple process, and it resolved my issue with the passenger side moving around. I was very impressed with Husky's customer service, and with the final fit of these floor mats. I've adjusted my review/rating accordingly.

UPDATE 1: I've had to adjust this to 3 stars, as the passenger side is not staying in place very well. This is probably just normal with vinyl flooring, but Husky claims their "StayPut Cleats" will keep them in place, so I was hoping they would work. They came with a floor anchor for the passenger side, but I'm not sure how well that would work with vinyl flooring, and I'm not exactly chomping at the bit to put a hole in the floor liner of my new truck in order to find out.

I ordered these for my 2016 Silverado 1500 double cab with vinyl flooring. I was a bit concerned as to how they would stay in place without the benefit of the retaining clip, but the fit is precise enough that they don't shift around at all. They provide good coverage... I especially like FormFit Edge that overlaps the door jam. I'm quite pleased with the fit and quality, and will be looking to get the 2nd row full coverage version for the back seats next.

These are great floor mats, they fit well in my 2016 sierra. I only wish they had taller sides at the toe end or far end of the mat.

Fits my 2017 GMC 1500 Denali!!!

So first, I see where other's comments were negative about the overlap on the sides; however, I like it because it allows liquid to run right out the vehicle instead of right down into the carpet (what would be the point of spending money on all weather mats if it didn't prevent this?!?!?)! I would not advise cutting it down to size: one, your side areas won't be protected; and two, even if you trim the raised areas, you'll end up having to trim more and more since the weight loss of some areas will make other parts raise (a buddy of mine did this and had to order them again because the sides of his carpet was exposed after he was said and done).

Second, as you can see in the driver's side back row, the mat lifts up quite a bit in the back; however, pinching it between the bottom door rail and the back seat support secured it a lot better.

Lastly, yes, the mat comes folded; but, it is of thick rubber made material (love this); once you have it adjusted in place, the heat will take out any slack left from the initial install (mostly found on the forward middle area of the mat where it contours over the sloped middle right behind the console).

To me, the full coverage of this mat provides in the back is well worth the $98! I would buy this product over and over and over again! With the money I spent on the truck (and the money you have spent on the truck), I definitely feel this is a good purchase in preserving the interior!
