The Topraco Under Seat Storage Bag for Tesla Cybertruck offers an affordable solution for creating extra storage under the Cybertruck's rear seats. The storage "boxes" come in a bag and are assembled using Velcro strips to form the box shape. There are straps that go through plastic D-rings to secure them to the truck's frame under the seat. While you may need to adjust the straps a bit for a snug fit when the seats are down, the setup is straightforward.You’ll get three storage "boxes" in total. The outer boxes are secured with straps, and the center box is held in place by Velcro to the two outer boxes.One downside compared to more expensive plastic storage solutions is that you can’t fit longer items under the seat, as the design is more compact. However, for the price, this is a solid and functional storage solution.

[Edited after finally figuring out - on my own with no provided instructions - how to install it]I was excited to get this so I could move up from current approach: "cram stuff in a couple of random bags and hope they roll out from under the seat."This product is a solid four and could easily become a five Star with good instructions (instead of zero instructions.) And there are attractives point to highlight. Let me break it down...Materials and Construction: 4 stars. I would have preferred heavier weight fabric all around. I don't know exactly what material is used in the stiffener panels, but I hope its not the kind of plastic that get brittle and shatters after sitting in a 120 degree F car for a couple of Texas summers. The sewing is solid. Nothing to worry about, but heavier fabric would make this area 5 stars.Design: 4 stars (as delivered without instructions). There are actually three "under-seat storage bags". Each of the bags arrive separated and folded up and fit in an adequate storage sack along with two straps. With no instruction I had to puzzle out the following: Each of the bags have four stiffener pieces sewn by one side to lower front or rear inside edges of the bag bottom. The stiffeners unfold to lay on the front and rear sides of the bag and are each held in place by a velcro flap. With the stiffeners in place the bags holds their box-like shape. Velcro hook and loop strips on the outside of the bag (now boxes...) attach the three bags into a single, fairly well-connected unit. The two larger bags fill the larger spaces under the outside rear seats, while a smaller bag spans most of the space between the other two. The smaller center bag is shorter front-to-back than the other two, only reaching back to the faces of the raised parts of the floor support the rear seat bottoms, leaving the space aft of the center bag unused (see photo). Even though the photo in the listing show the product installed in a different brand truck, it does appear to be tailored specifically for the Cybertruck. I say this because of the fit within the unique under-seat space of the Cybertruck and the way the bag assembly is secured from sliding forward. There are light-weight plastic loops sewn onto the center of the back of the outside bags. Two long straps with typical adjustable quick release buckles are used to connect those loops to a horizontal strut running just above the floor beneath the seat back, securing the bags to the truck. Without instructions, the method for assembling and installing the product was an irritating puzzle. If the instructions were included and made sense, I'd give the design five stars.Functionality: 5 stars for light object storage - 3 stars for heavier objects. Call it 4 stars overall. I suspect this aspect will depend on what is stored in the unit. Low mass things like some clothing, light weight cordage, and such will work fine, but high mass items like tools, containers of water or other liquids may force the unsecured bags forward somewhat under spirited driving."Handiness": 5 stars. The fact the this storage system can be folded up, put in a reasonably small sack and itself be stored away makes it very handy. If I need the whole rear floor to load large objects I can remove this storage system easily find a place to tuck it away.Value for Money: 5 stars. The purchase price for this bag-style under seat storage is about 20% that of competing plastic box-type products that are likely to cause rattles and can't be folded up and put away to clear the rear floor to load large items.Overall: 4 stars. If the vender adds any sort of useful instructions this score would go up to five stars.

This under seat storage bag fits perfectly in my 2024 Cybertruck. It’s well-made, durable, and holds tools and accessories securely without sliding around. Great use of space that would otherwise go unused. Keeps everything organized and out of sight. A must-have accessory if you want to keep your truck clutter-free!
