Isofix in a campervan: which vehicles are compatible ?

In short:

Vans with a factory-fitted rear bench (California, Marco Polo...) usually have isofix as standard
Converted vans with a bed-bench added by a converter often don't
No isofix? A dual-fit seat installs with the 3-point seatbelt — fully approved and safe
A big, heavy car seat makes setting up the bed a hassle and eats living space, especially in compact vans

What is isofix, exactly?

Isofix is a standardised anchoring system: two metal rings bolted to the vehicle's chassis, tucked between the seat base and backrest. The child seat clicks straight onto them, no seatbelt needed. The result is a rigid fit that's almost impossible to get wrong — whereas a badly installed belt-fitted seat is the most common mistake parents make.

Good to know: most recent child seats are "dual-fit". They install with isofix or with the 3-point belt. So your seat isn't useless if the van has no anchor points — more on that below.

Why some vans have isofix and others don't

This is where the leisure vehicle world splits into two families.

Factory-built vans — think California, Marco Polo or Nugget — leave the plant with their original rear bench, designed and approved by the car manufacturer just like in a regular car. These benches usually come with isofix anchors as standard. You click your child's seat in exactly like in your own car.

Converted vans — the second family — start life as a commercial van transformed by a converter. The rear bench isn't the manufacturer's: it's a bed-bench installed afterwards, designed first and foremost to fold out into a bed. It's approved with its 3-point belts, but it doesn't always include isofix rings. That's not an oversight: building isofix anchors into a folding bed-bench adds real technical and approval constraints, and not every converter takes them on.

Bottom line: before booking, check the vehicle listing or ask your branch directly. At Blacksheep, part of the fleet is isofix-compatible, part isn't.

No isofix? You can still travel with your kids

No anchor points doesn't mean no kids on board. In Ireland, children under 150 cm or 36 kg must travel in an appropriate child restraint — isofix or not. Rules are similar across Europe, so check the country you're driving through.

In practice, in a van without isofix:

Dual-fit car seat: secure it with the bench's 3-point belt, following the belt path marked on the seat. Tight and snug, it's approved and safe.
Booster seat: for older kids, the booster is held by the child's weight, and the vehicle belt restrains the child. No anchors needed.
Avoid: DIY hacks to "create" an isofix point. If the vehicle doesn't have one, the belt installation is the approved method, full stop.

Friendly tip: do a practice install at the branch before hitting the road, rather than in a supermarket car park with two impatient kids.

The real issue nobody mentions: space and the bed routine

This is the point nobody talks about — and yet it's the one that will shape your whole trip.

A big car seat — especially a wide, rear-facing group 0+/1 model — can weigh 10–15 kg and take up a good third of the bench. In a compact van, that has two very real consequences:

At night, to set up the bed, the bench needs to slide or fold. With a car seat clicked onto it, that's impossible: you have to unclip it, take it out, find it a home… then put it all back the next morning. Doing that twice a day for two weeks wears you down.
During the day, it shrinks your living space. In a small vehicle, the cabin is your lounge, kitchen and bedroom all at once. A bulky car seat lying around means less room to cook, play or simply move — and no obvious spot to store it at night.

Our tips to skip the hassle:

Pick the most compact, lightest seat suitable for your child's age. The plush seat you use at home isn't necessarily the right one for the van.
Decide where it sleeps: front passenger seat, under the bed, in the shower cubicle on larger vehicles… settle it on day 1, not every evening.
If your kids are booster age, go for it: light and flat, it slips in anywhere.
Travelling with a baby and a big seat? Go for a spacious van rather than a compact one. The daily comfort is well worth a few euros more per day.

How to pick your Blacksheep van for a family trip

Three questions before you book:

Is your seat isofix, belt-fitted, or dual-fit? Check the manual or the label on the side of the seat.
Does the van you're eyeing have isofix anchors?
What vehicle size for what seat size? Big seat = go spacious. Booster = anything works, even the most compact vans.

Not sure? Call your Blacksheep branch — the team knows their vehicles inside out and will tell you straight away what works with your gear and your kids. And to plan the rest of the trip, check out our article on road tripping with kids.

FAQ

Do all campervans have isofix? No. Vans with a factory-fitted rear bench (California, Marco Polo type) usually do. Converted vans with a bed-bench added by a converter often don't.

Can I install a car seat without isofix in a van? Yes. Most recent seats also install with the 3-point belt, and boosters don't need anchors at all. The key is following the belt path shown by the manufacturer.

Up to what age is a child seat mandatory in a campervan? Same rule as in a car. In Ireland: children under 150 cm or 36 kg must use an appropriate child restraint. Check local rules for the countries on your route.

Where do I store the car seat at night in the van? Front passenger seat, under the bed or in a storage area depending on the model. Pick one fixed spot on the first evening — it's the move you'll repeat every day.
