SMARTLINER Truck Rugged Rubber Bed Mat Liner for 2019-2021 Silverado/GMC Sierra 1500 Only Fits Crew Cab with 5'8" Short Bed, Black

The media could not be loaded.  Fits perfect in 2021 Silverado 5’8 bed. Feels very durable. I can see how water retention may be an issue because there are no drainage holes but I have bed cover so that issue seems minor in my case. Very pleased. My only complaint is not about the product itself but the shipping. It took 7 days when it was listed as a prime item and it came USPS, not FedEx or UPS. They would not deliver it because it was an “oversized item” so I had to go wait in line at the post office to pick it up. Kind of a pain because I was expecting it delivered to my doorstep. Just a detail that would have been nice to know. Product 5 stars, shipping not so much.

Great quality, very durable, excellent fit. The only issue I've had is water pooling up since there are no drain holes. You can cut holes in the liner to drain but water will evaporate quickly in warmer weather.Cargo does not slide. This liner has a lot of grip. Very pleased. The best bed mat type liner I've ever used.

I have had it for a few weeks and it still hasn’t completely flatten out. I also didn’t realize it was going to have a 2” lip around the edge that doesn’t lay flat. It turns the mat into a faint bowl of water gets on it. Other than that, it fits good.

I bought this mat since I don’t have a bed liner. Yeah, it’s a mistake I made but this mat has been very useful. I do a lot of payload and with the mat being thick and easy to install/remove. It made things so much easier. To maintain your paint I suggest removing it before a wash.

It fits great on my GMC Sierra 1500, even with the carbon bed liner.

The thickness and quality of this mat is great! It's soft on your knees if you're crawling around in the bed and it's super grippy. Stuff is not going to slide around! It's a little harder to take in and out than other mats I've had just because it's so thick and heavy. The raised edges are nice to keep stuff from getting underneath it. However, I did drill a couple of drain holes, as others have mentioned, so that it doesn't retain water. I'm also not sure I like the raised lip on the tailgate end... It makes it a little harder to get things in and out (you can't really slide stuff from the tailgate into the bed. I may end up trimming the back lip off if it gets in my way too much. Overall, I'm happy though.

This was much thinner than I expected. It came rolled up tight in a small long box and no adhesive was in there. It took a long time to get it to lay flat. It also has a lip ALL the way around, which didn’t make a lot of sense to us. That leaves no where for water to drain when we do get rain. Just seemed much cheaper quality than what I paid for

When I initially installed the liner I thought I might have to trim it until I let it sit in the sun. It shrunk up perfectly and fits like a glove! This is a excellent quality bed liner that protects the bed and keeps cargo from sliding.
