For most cars, choose a collapsible bin with dividers, a non-slip base and straps, because it adapts to the widest range of loads. Choose a hanging organizer or a cargo mat with movable blocks instead if you need the floor clear for luggage or bulky gear. Either way, a trunk organizer keeps loose items in one place so they don’t roll around, spill or get buried.

How to choose a trunk organizer
“Trunk” is the US term for the space the UK calls the “boot”. This guide uses “trunk” throughout.
Pick the right type
Collapsible bins are fabric boxes with removable or fold-down dividers. They handle groceries, cleaning supplies, sports gear and emergency items well, and most fold flat.
Fixed or rigid dividers stay put and keep their shape. That helps if you carry the same items every day, such as tools or work equipment. The trade-off is that they take up space even when nearly empty.
Hanging back-seat organizers strap around the rear headrests and hang into the trunk. They use vertical space and leave the floor clear, but they only hold smaller, lighter items. Check that they won’t block a folding seat or a cargo cover.
Cargo nets stretch across the trunk floor or along a side wall. They are light and stop bags and bottles from tipping over, but they don’t separate items. Many cars already have anchor points for a net.
Cargo mats with movable blocks let you build walls around items of any shape. They suit loads that change a lot, from a suitcase one day to plants the next.
Measure your trunk before you buy
Measure 3 things:
- the floor width between the wheel arches
- the depth from the back of the rear seats to the trunk lip
- the height to the rear shelf or cargo cover
Compare those numbers with the organizer’s listed dimensions. A bin needs to sit clear of the wheel arches to stay flat. In a small hatchback, a medium bin or a hanging organizer often works better than an extra-large bin that leaves no room for anything else.
Keep the organizer from sliding
Loose items can slide or tip over under hard braking or sharp turns. A heavy object moving around the cabin can be a hazard. Look for a non-slip or hook-and-loop base, plus straps or hooks that attach to your trunk’s tie-down points. Pack heavy items low and toward the rear seats, and use proper tie-downs for heavy loads.
Do you need a cooler compartment?
Some organizers come with an insulated or cooler bag. A removable cooler is easier to clean, and you can leave it at home when you don’t need it. Treat it as a way to keep things cool on short trips, not as a replacement for a full-size cooler.
Protect the carpet from water and mud
If you carry wet boots, beach gear, plants or a dog, a waterproof base or a full cargo liner protects the carpet underneath. Raised or piped edges help keep water and dirt in. For seats as well as the trunk, see the car seat cover buying guide.
Check the materials
Most bins use polyester or similar woven fabric with stiffening boards in the walls or base. Thicker fabric and rigid base plates help a bin hold its shape when it is half full. Thermoplastic mats rinse clean, and you can wipe down eco-leather or vinyl.
Check how it folds away
If you sometimes need the whole trunk for luggage or a big grocery run, check how small the organizer folds. It also helps if it collapses to 1 compartment. For trips that need more space than the trunk gives, the roof racks and cargo boxes guide covers the next step up.
What each organizer offers

Fortem sells its Premium Extra Large model with a cooler bag. It offers up to 6 compartments, multiple side pockets, mesh siding and elastic pockets for small items. Fortem says rigid base plates reinforce the bin and that the bottom half is waterproof.

Husky Liners Cargo Logic
Cargo Logic is a 30 x 36 in (76 x 91 cm) mat with 4 Cargo Lok cleats (8 pieces in total). The mat uses the same all-weather thermoplastic as Husky’s floor liners, with a carpeted layer bonded to the top. The cleats have hook-and-loop material underneath that latches into that carpet. You can place them around items of almost any shape.
A lip runs around the edge of the mat. Husky says the mat withstands rain, mud and snow and cleans easily. It suits awkward or changing loads, such as coolers, plants or sports bags.

Owleys Hold&Go hanging trunk organizer
The Hold&Go hangs from the rear headrests with 3 adjustable straps, and 2 side anchors add stability. Owleys says it works with 2 or 3 headrests. Unfolded, it measures 39 x 19 in (100 x 48 cm), and it folds to 19 x 13.4 in (48 x 34 cm). It weighs 2.7 lb (1.2 kg).
It has 8 pockets, and the 2 top middle pockets fit bottles up to 51 fl oz (1.5 L). The materials are eco leather, nylon, metal and recycled ABS. Owleys says it wipes clean with a damp cloth.
It suits SUV and hatchback owners who want to keep the trunk floor clear for luggage or a stroller.

Kurgo Rover Cargo Cape
The Rover Cargo Cape is a full cargo-area liner, not an organizer. It measures 52 in wide by 62 in long (132 x 157 cm), and Kurgo says it fits most vehicles’ cargo areas.

Frequently asked questions
What size trunk organizer do you need?
Measure the trunk floor width between the wheel arches and the depth from the seatbacks to the lip. Compare those numbers with the organizer’s listed dimensions.
Will a trunk organizer slide around while driving?
It can if it isn’t anchored. Choose one with a non-slip or hook-and-loop base and straps that attach to your trunk’s tie-down points. Pack heavier items at the bottom.
Should you choose a hanging organizer or a bin?
It depends on the load. A hanging organizer keeps the floor clear but holds only smaller items, while a bin holds more. Some owners use both.
Are trunk organizers waterproof?
Some are, partly. Fortem describes the bottom half of its Premium model as waterproof, and Thule calls the Go Box water resistant. For full protection of the carpet, use a waterproof liner or a thermoplastic mat underneath.
Can you use a trunk organizer on the back seat?
Many collapsible bins can move to the back seat or fold down to a single compartment. If you do, secure it with the seat belt or its own straps so it can’t move under braking.
