Tmat Truck Bed Organizer Slide Out Mat | Rivian R1T
Organize your Rivian R1T’s bed with a cargo management system designed for modern truck bed organization. Adjustable blockers fit into the mat in any arrangement, creating compartments for tools, gear, and equipment. The system fits between the wheel wells and slides toward the tailgate for quick access. Works with drawer systems, bed slides, and other custom setups.
WARNING: Tmat is designed for enclosed and covered cargo areas such as covered truck beds, SUVs, vans, campers, and enclosed trailers. Extra precautions must be taken to properly secure Tmat when used in an open-air cargo area to protect from wind and roll-overs. Tmat should never be used in an open-sided bed or with the tailgate down.

Competitor ranges are estimates for comparison.
Tmat kits are sized for midsize (Tacoma, Ranger, Colorado), short bed (F-150, Silverado 1500, Ram 1500, Tundra), standard, and long bed trucks (Super Duty, HD, 2500/3500). Use the vehicle selector above or shop by make to find your exact fit.
The paneling system handles heavy static loads without crushing or deforming - stacked toolboxes, full coolers, job-site hardware. Sliding works smoothly with loads of a few hundred pounds during loading and unloading.
Bed slides ($1,500+) give pull-out access but zero organization and bolt permanently. Tmat gives you slide-out access AND modular organization - no drill installation, a fraction of the cost, and it comes out in seconds if you need your full bed back.
None. Zero. Panels snap together by hand, blockers push into the grid by hand, and the assembled mat slides into your bed with no drilling, brackets, or permanent modifications.
Tmat is designed for enclosed/covered cargo areas - tonneau covers, camper shells, SUVs, vans, enclosed trailers. Open-bed use requires extra precautions against wind. Never use with the tailgate down.
90-day returns, no hassle. Send it back if it's not for you. Every kit is also backed by our Lifetime Warranty - if something breaks from a manufacturing defect, we replace it. Zero risk. More information on our return policy here.

Nick Timura built the first Tmat prototype. A team of ten spent 13 years and 400,000+ miles of testing perfecting it.
Tmat is still manufactured by the Timura family, who bring 100+ years of combined engineering experience to every system. Each Tmat is made from a UV-stable, impact-resistant polymer built for outdoor life, which is why we can back it for life.
The mat installation is easy and efficient
Configured to carry our trapshooting equipment, that keeps everything in place.
Perfect fit and addition to my 2026 Silverado HD 2500, very easy to install, easy to use and nice sliding so I can reach for my tools box. Well done 👍
I highly recommend the Tmat Truck Bed Organizer! For the price, I don't think there's a better option on the market. It's lightweight, incredibly versatile, and very easy to install. The fit in my truck bed is perfect, and it looks great.
The mat easily slides in and out over my spray-in bed liner. It's also extremely easy to clean, which is a huge plus. The versatility of the system makes it even better, especially considering the price.
My only minor complaint is that I wish the kit included a few male-to-male connectors for the single-row edge pieces. It would have been a nice addition and made the kit feel a little more complete.
Overall, I'm extremely satisfied with the quality, functionality, and value of this product. It's a great design, works exactly as I hoped, and I would highly recommend it to anyone looking for an affordable and versatile truck bed organization system.
I keep finding new uses for these...
Hardly any bin/box/etc is going to be the exact size for the spacing of the holes and traditional blockers. This solves that problem! Adjust it right up to hold your stuff snug.
Simple install, keeps my truck bed organized and very easy to adjust.
I purchased the Tmat system for my RAM Rampage and had it shipped to Costa Rica. Since the Rampage is not currently listed among the available vehicle configurations, I was initially unsure whether the system would fit properly.
I’m very happy to say that it fit my truck perfectly. The modular design made it easy to adapt the layout to the dimensions of the Rampage bed, and the system looks clean, organized, and very functional.
I also want to highlight the excellent customer service. I contacted the Tmat team with several questions about measurements and fitment, and they were extremely helpful, responsive, and willing to review photos and dimensions to make sure everything was installed correctly.
Overall, I am extremely satisfied with my purchase. Even though the RAM Rampage is not officially listed yet, Tmat worked perfectly for my truck. I would definitely recommend it, especially to other Rampage owners looking for a practical truck bed organization system.
Greetings from Costa Rica! 🇨🇷
This product is great when you're off-roading and really keeps everything in place. I took it out for a test the same day i installed it and i just love it. Just keep in mind that to perfectly fit a 2025 tahoe you need 16 12x12 squares.
Bought several of these for my Milwaukee pack out in my truck. They keep things tight with Zero movement.
Added the Early Release* DIY Bed Dividers fits 2x4 (3-Pack). This works great for smaller items that you don't want to put inside your truck but you don't want rolling around in the bed. Easy to install and easy to take out when you need that extra space. I cut the board to my linking, I wanted maximum coverage without struggling to put it in and take it out. then place the dividers where I wanted them and drilled out the holes. I then used a truck bed spray paint applying two coats on each side. Then put everything back in place and bolted everything together. The total time with painting was 4 hours, but most of that was waiting for the paint to dry. Without paint the total time would have been roughly 20-30 minutes.
The Sequoia Hybrid is lacking "controllable" storage when the third row seating is down. 16 of these panels fit perfectly in that space and protects the seat backs. Slides in and out easily. The adjustable blockers are a must have with this setup.
