Although this is a versatile item, it will not fit the standard size Silverado rear seat because it is too narrow. Simply adjusting the passenger side strap that goes around the headrest to hold the cover in place resulted in the seams tearing. The bottom of the lid is held in place by two elastic straps that are missing from the top of the lid and would have been a better fastening solution. The headrest covers are huge and can't be made smaller without modification, but that's to be expected from a versatile item as you can always tuck in or trim excess, but it doesn't work the other way around. Since it's basically a replacement for an old towel to protect the back seat from a full line of kids in their car seats and their snacks, it's fine. If this was to be used as an adult seat cover I would return it.
