1. Trunk Organizer by Drive Auto Products: Best Overall
The Drive Auto Products Trunk Organizer is a well-built storage solution for keeping groceries, tools, and sports gear secure in your trunk. Its collapsible design with rigid sides and adjustable dividers allows you to customize compartments for different items. The non-slip rubber base prevents sliding, which is a common issue with cheaper organizers. Based on owner feedback, the 600D polyester fabric holds up well to regular use and is easy to wipe clean. In our evaluation, this organizer offers the best balance of capacity, durability, and versatility for most drivers.
However, the organizer is fairly large even when collapsed, so it may not be ideal for those who need to maximize trunk space for luggage or bulky items. The dividers can be a bit stiff to adjust initially. If you have a very small trunk or frequently need to fold the organizer flat, consider a softer collapsible model instead.
- Collapsible design with rigid sides and adjustable dividers for custom organization
- Non-slip rubber base keeps the organizer stable during turns and stops
- 600D polyester fabric is water-resistant and easy to clean
Pros: Sturdy construction with reinforced stitching; Adjustable compartments fit various item sizes
Cons: Takes up significant trunk space when fully expanded
2. Seat Gap Filler by BAGSMART: Best for Small Items
The BAGSMART Seat Gap Filler is a practical solution for preventing phones, coins, and other small items from falling into the abyss between your seat and center console. It features two storage pockets that can hold a smartphone or wallet, making them easily accessible while driving. The PU leather material is soft and blends well with most interiors. According to owner reviews, installation is straightforward and the filler stays in place without sliding. We found this product to be a low-cost way to add convenient storage and reduce clutter.
One limitation is that the filler may not fit all seat gaps perfectly, especially in vehicles with unusually wide or narrow gaps. Some users reported that it can shift slightly over time. If your car has a very tight gap or you prefer a more integrated look, a custom-fit option might be better. Also, the pockets are not very deep, so larger items may not stay secure.
- Fills the gap between seat and center console to prevent items from falling
- Includes two side pockets for phone, wallet, or keys
- Made of soft PU leather that matches most car interiors
Pros: Easy to install and remove, no tools needed; Keeps small items within easy reach
Cons: May not fit all vehicle seat gap sizes perfectly
3. Cargo Net by Olympic: Best for Cargo Security
The Olympic Cargo Net is a heavy-duty elastic net designed to keep loose items secure in the cargo area. It stretches to accommodate various shapes and sizes, making it ideal for groceries, camping gear, or sports equipment. The four hooks attach to existing tie-down points or headrest posts, and the net holds items firmly in place. Based on owner feedback, the elastic retains tension well over time. In our evaluation, this net provides excellent cargo security and is a smart addition for any SUV or hatchback driver.
However, the net’s open weave means smaller items like soda cans or bags of chips could slip through if not packed carefully. It also requires existing attachment points, which some vehicles may lack. If you need a fully enclosed storage solution or have a car without tie-downs, consider a trunk organizer or cargo box instead.
- Stretches to secure odd-shaped items like groceries or luggage
- Includes 4 sturdy hooks that attach to cargo tie-downs or headrest posts
- Elastic construction keeps items from shifting during transit
Pros: Highly versatile and easy to move between vehicles; Improves safety by preventing cargo from becoming projectiles
Cons: May not fully contain small items if netting is too loose
4. Backseat Organizer by SHUOYAO: Best for Families
The SHUOYAO Backseat Organizer is a family-friendly storage solution that attaches to the back of front seats. It offers a variety of pockets, including a clear tablet holder and a built-in cup holder, making it perfect for keeping kids entertained and organized on long drives. The adjustable straps and anti-slip buckles ensure a secure fit on most seatbacks. According to owner reviews, the material is durable and easy to wipe clean. We found this organizer to be a practical way to manage backseat chaos without taking up floor space.
One drawback is that the organizer can limit front seat legroom if the seat is moved forward too much. Some users reported that the tablet pocket is not large enough for bigger devices. Also, the cup holder may not securely hold larger bottles. If you have tall front-seat passengers or need a more minimalist solution, a smaller seatback pouch might be preferable.
- Hangs on front seatbacks with adjustable straps and anti-slip buckles
- Multiple pockets for toys, tablets, snacks, and water bottles
- Includes a clear tablet pocket for entertainment on road trips
Pros: Keeps backseat clutter organized and within reach for passengers; Easy to install and remove for cleaning
Cons: May interfere with front seat adjustment if not positioned correctly
5. Under Seat Storage Box by Aenllosi: Best Hidden Storage

The Aenllosi Under Seat Storage Box is a discreet storage option that tucks under your car seats, using space that often goes to waste. The hard plastic case has a locking lid, making it suitable for storing valuables like documents, tools, or emergency kits. The carpet-like finish helps it blend with the floor. Based on owner feedback, the box slides easily and stays in place. We appreciate the added security of a lock, which is rare for under-seat storage.
However, the box’s dimensions may not fit under seats with low ground clearance or when seats are fully forward. Some users noted that the latch can be flimsy. Also, accessing items requires pulling the box out, which can be inconvenient. If you need quick access to stored items, a seatback organizer or console tray might be better.
- Slides under front or rear seats to utilize unused space
- Locking lid keeps valuables secure and out of sight
- Made of impact-resistant plastic with a carpet-like finish
Pros: Maximizes hidden storage without cluttering visible areas; Secure locking mechanism deters theft
Cons: May not fit under all seats due to limited clearance
6. Console Vault by Console Vault: Best Security

The Console Vault is a high-security storage safe that installs inside your vehicle’s center console. It is made of heavy-gauge steel with a pry-resistant lock, providing protection for valuables such as firearms, wallets, or important documents. The vehicle-specific design ensures a tight fit, and the bolt-in installation makes it difficult to remove. Based on owner feedback, this vault offers peace of mind for those who need to secure items in their car. In our evaluation, it is the most secure storage option available.
However, the installation is permanent and requires drilling into the console, which may void some warranties or be undesirable for leased vehicles. The cost is also higher than other storage solutions, and the interior space is limited. If you don’t need extreme security or want a removable solution, a locking under-seat box or a simple lockable glove box might suffice.
- Custom-fits inside your center console for a seamless look
- Made of 16-gauge steel with a pry-resistant lock
- Bolt-in installation provides permanent secure storage
Pros: Extremely secure for valuables like guns, cash, or documents; Vehicle-specific design ensures precise fit
Cons: Installation requires drilling and is not reversible
7. Trunk Cargo Carrier by Rightline Gear: Best for Road Trips
The Rightline Gear Trunk Cargo Carrier is an external storage solution that attaches to the trunk lid of sedans and some hatchbacks. It provides up to 15 cubic feet of additional waterproof storage, ideal for road trips when you need extra space for luggage or camping gear. The adjustable straps and anti-sway design help keep the carrier stable while driving. According to owner reviews, the material is durable and the carrier holds up well in rain. We found it to be a practical option for maximizing cargo capacity without a roof rack.
However, the carrier blocks the rear window, reducing visibility, and can increase wind resistance, which may lower fuel economy. Some users reported that the straps can loosen over time, requiring periodic checks. Also, it is not compatible with all trunk designs. If you frequently need extra space and don’t mind the trade-offs, this carrier is a good choice. For those who prioritize safety or have limited trunk lid clearance, a roof box might be a better alternative.
- Attaches to trunk lid with adjustable straps and anti-sway design
- Waterproof construction protects gear from rain and road spray
- Large 15 cubic foot capacity for extra luggage on trips
Pros: Significantly increases cargo capacity for road trips; Folds flat when not in use for easy storage
Cons: Can reduce rear visibility and may affect fuel economy
Frequently Asked Questions
What is the best type of extra storage for a car?
The best type depends on your needs. For general trunk organization, a collapsible trunk organizer with dividers is versatile. For small items like phones and coins, seat gap fillers or console trays work well. Families may prefer backseat organizers, while security-focused users might choose a console vault. Consider your vehicle’s space and how you plan to use the storage.
How do I install a seat gap filler?
Most seat gap fillers are wedge-shaped and simply push into the gap between the seat and center console. No tools are required. Some models have adjustable straps or tabs that tuck under the seat cushion to prevent movement. Ensure the filler is snug but not forcing the seat out of position.
Are trunk cargo carriers safe?
External trunk cargo carriers are generally safe when properly installed and not overloaded. However, they can reduce rear visibility and increase wind resistance. Always follow the manufacturer’s weight limits and check strap tightness periodically. Some vehicles may not be compatible due to trunk design or rear camera placement.
Can I use a cargo net for heavy items?
Cargo nets are best for securing lightweight to medium-weight items like groceries, bags, or sports gear. They are not designed for heavy or sharp objects that could tear the net or become projectiles. For heavy items, use a rigid trunk organizer or tie-down straps with hooks.
Will a console vault fit my car?
Console Vault offers vehicle-specific models for many makes and models. Check their website or Amazon listing to confirm compatibility. The vault is designed to fit inside the center console, so you need to remove the existing liner or tray. Installation may require drilling, so ensure you are comfortable with a permanent modification.
