By the second hour of a road trip, the back seat usually looks like a small explosion in a stationery shop. Crayons are on the floor, a tablet is under a seat, and someone is crying because a drink rolled out of reach. Car organisers solve this. They also raise a safety question most product pages skip: everything in the car travels at the speed of the car, and it keeps moving when the car stops. This guide looks at how to choose an organiser, what to put in it, and what shouldn’t be in it at all.
Quick answer
- Soft, light items only in seat-back organisers and anywhere near a child’s head.
- Put heavy or hard things in the boot, secured, or low down on the floor. The Highway Code says heavy or sharp objects must be secured safely, because they might hit someone in a collision.
- Nothing goes between a child and their car seat. The AAP advises against add-ons that didn’t come with the seat, or that the seat’s maker hasn’t approved.
- Don’t block what you need to see or use: your rear view, the seat belts, buckles or any airbag covers.
- Choose by age. A toddler can’t reach much. An eight-year-old can manage their own organiser.
Why loose items matter
This is the reason to take organisers seriously rather than just treating them as tidiness. Rule 98 of the UK’s Highway Code says you must secure your load, and that heavy or sharp objects and any animals must be secured safely, as they might hit someone inside the vehicle in a collision and cause serious injury. Safe Kids Worldwide’s car seat advice tells parents to secure loose objects, so they can’t become projectiles in a crash, and to choose soft toys that won’t hurt a child.
In practice, a metal water bottle in a mesh pocket, a hardback book on a parcel shelf, or a tablet in a plastic holder all deserve a second thought. An organiser can reduce the risk by giving items a place, or it can add to it, by putting hard objects at the height of a child’s head. So the choice of what goes in it matters more than which one you buy.
Decision table: types of organiser
| Type | Good for | Age | Safety checks | Limitations |
|---|---|---|---|---|
| Seat-back organiser | Wipes, soft toys, books, snacks | Reachable from about 3 upwards | Soft contents only; fits firmly with straps at top and bottom | Rear-facing seats may leave it out of reach |
| Kick mat with pockets | Protecting seats; thin items | Any | Keep it flat; keep contents light | Small capacity |
| Between-seat soft box | Older children sharing a seat row | 5 and up | Must not interfere with buckles or belt; secure it | Not possible with three seats across |
| Headrest tablet holder | Long stretches of motorway | Depends on the child | Soft case or a fabric sleeve is better than a hard arm | Hard mounts could be a head-strike risk; screen can cause car sickness |
| Footwell box or bag | Heavier snacks, drinks | Adult-accessible | Keep it low; check it can’t roll under the driver’s pedals | Takes up leg room |
| Boot organiser | First-aid kit, kit for stops, heavier items | Adults | Secure it with straps or a net, and keep heavy things low | Reach only at stops |
| Cool bag | Food and drinks for the day | Adults | Secure it, and don’t store it on a child’s seat | Heavier when full |
What to put where
| Item | Best place |
|---|---|
| Soft toys, wipes, tissues, spare socks | Seat-back organiser |
| Paperback books, thin pads, a soft pencil case | Seat-back organiser |
| Plastic or silicone snack pots | Seat-back organiser or a bag in the footwell |
| Metal bottles, glass containers, heavy flasks | Boot, or low and secured |
| Tablets | Secured in a soft case; stowed when not in use |
| First-aid kit | Reachable by an adult; boot or under-seat storage |
| Medicines and sharp scissors | Out of children’s reach |
| Medicines that need to stay cool, or anything else that heat can spoil | Cool bag, out of the sun |
| Sun protection, jackets | Bag in the boot; bring in for each stop |

How to fit an organiser securely
- Read the instructions and your car’s manual. Headrest posts and seat shapes vary.
- Use both straps. A top-only strap swings about when you brake or corner. Look for a lower strap around the seat base.
- Check it doesn’t block anything. Keep it clear of airbag labels on the seat, seat belts, ISOFIX or LATCH points, and any recline or fold levers. The car’s manual shows where seat-mounted airbags are located.
- Do the “shake” test. Give it a firm shake. Nothing should fall out, and the organiser shouldn’t move far.
- Do a child-height check. Sit next to the child’s seat. Could anything hard reach their head or face if it came loose?
- Check that it doesn’t get in the way of the car seat. Some car seats must rest against the seat in front or touch it in a specific way. Look at your seat’s manual.
Car seats and add-ons
A related point is that organisers and accessories should stay away from the seat itself. The AAP’s car seat advice says to avoid extra products unless they came with the seat or are specifically approved by the seat’s manufacturer, as these products aren’t covered by federal safety standards. It also says not to put padding or inserts under or behind a child unless the manufacturer made them for that seat. So don’t hang a pouch from the harness, attach a toy to a strap, or wedge a tray across a child’s lap unless the manufacturer approves it. If a tray or play surface is sold for car use, read how it should be used and how it is secured.
Keep the essentials visible. Harness buckles need to stay clear for a quick release, so don’t tuck anything around them.
Rear view and driver distraction
Don’t pile items so high you can’t see through the rear window. Even when it isn’t a specific rule, a blocked view makes driving harder. Keep what the driver might need, such as a phone mount or sunglasses, in a place where it doesn’t need any reaching. If a child needs something, pull over at a safe place rather than reaching back. If an adult is in the back, this is their job. With younger children, a good rule is that everything they might need for the next hour should be within their own reach or an adult passenger’s.
Keeping it useful by age
- Babies: a rear-facing baby can’t reach a seat-back organiser. The Lullaby Trust recommends an adult in the back on long trips. Keep nappy things in a soft bag next to them.
- Toddlers: keep soft books and a few toys in reach, and rotate them at stops. Secure any toy with straps only if it’s soft and can’t wrap around a neck. Avoid long cords.
- Ages 4 to 8: give each child their own pocket or pouch. See activity books for ages 4 to 8, and our note about reading and car sickness.
- Older children: they can manage a bag at their feet. Keep it light and let them keep a tablet in a sleeve.
What to avoid
- Glass or metal in a seat-back pocket. Use plastic or silicone.
- Hard plastic trays or tablet mounts at face height. If you must use one, take it down when not in use.
- Long straps and cords within a young child’s reach. They’re a strangling risk. Keep charging cables out of reach, too.
- Melting things. Crayons, chocolate and some sun creams don’t do well in a hot car. Pack them in a cool bag or at the back.
- Too many pockets. The more you can store, the more you take with you. Empty it at every overnight stop.
- Trusting “crash-tested” as a label. Ask what standard was used, and whether it refers to the organiser, the fittings or the contents.
Rental cars
Choose something that packs flat and has straps that adjust. Headrests and seat shapes will be unfamiliar, so check before you buy. Keep your organiser in your luggage, and fit it when you collect the car. Don’t leave valuables on display when you stop, including a tablet in a seat-back pocket. Take a photo of the empty car, too, so you can check you’ve left nothing behind when you return it.

Final thoughts
<p>Keep soft, light items in seat-back organisers and put heavy or hard things low down and secured or in the boot. Fit straps top and bottom, keep clear of belts, buckles and airbag covers, and don't add anything to a car seat unless its maker approves it. Empty it at every overnight stop.</p>
Frequently asked questions
Are seat-back organisers safe?
They can be, if they're fitted firmly and hold only soft, light items. Heavy or hard things belong in the boot or low down and secured.
Can I attach toys to my child's car seat?
The AAP advises against add-ons unless they came with the seat or the seat's maker has approved them. Read your manual.
Where should I put a metal water bottle in the car?
Somewhere low, secured, and away from the head height of anyone in the car. Use plastic or silicone bottles within children's reach.
Are tablet holders safe in a car?
A hard holder at a child's face height is worth thinking twice about. A soft case is a gentler option. We found no official test that shows a specific type is safe, so stow devices when not in use.
Do I need to secure luggage in the boot?
The Highway Code says you must secure your load, including heavy or sharp items. Straps, nets and cargo barriers can help.
