Car seat for a small car
In a city car, a rear-facing seat can leave the front passenger with no legroom. How to measure, what to check and four compact seats.
In short
- The problem is not the width but the length – how much room the rear-facing seat takes from the front seat.
- Before anything else, check the manufacturer’s compatibility list for your car’s model and year.
- Do not turn the child forward-facing earlier just to gain space. Change the seat, not the direction.
Small city cars are perfect until a rear-facing car seat shows up on the back seat. Then you find out that the front passenger sits with their knees against the dashboard, that the support leg lands exactly on a cover in the floor, or that the rear door opens too little for you to place the child.
None of these problems is unsolvable, but they are all solved before you buy, not after.
As in everything we write about car seats, we rely on the UN R129 (i-Size) regulation and on manufacturer data. We have not done installation or crash tests.
What to check in the car
- Where you have ISOFIX. Usually on the outer rear seats; sometimes on the front passenger seat too. It says so in the car’s manual.
- The floor. If under the rear passengers’ feet there are storage compartments with a lid, the seat’s support leg may not be allowed to stand on them. The car’s manual says what is permitted.
- The available length. Move the front seat to the position where an adult sits comfortably and measure from the rear seat backrest to the front seat backrest.
- The angle of the rear seat. Very steeply angled rear seats can lift an infant carrier too upright; some bases have recline adjustment precisely for this.
- The door opening. In three-door cars or cars with short rear doors, a rotating seat helps a lot.
The mistake to avoid
In a small car the temptation is to turn the child forward-facing as soon as the law allows, because that way it “fits”. R129 sets the minimum at 15 months, but the rear-facing position protects better after that age too. If the current seat does not fit, the solution is a more compact seat, not a less safe direction. We explained why in the car seat guide.
Four seats that need little space
Joie i-Snug 2
Budget-friendlyWho it suits: the first year, in any small car, especially if the shell is fitted with the seat belt.
In a small car, a shell fitted with the seat belt is often the simplest solution: it does not depend on the floor and takes up little length.
Pros
- Short, light shell, R129 approved
- Fitted with the car’s seat belt, without a base – no worry about the support leg
- Optional ISOFIX base, if the car allows it
- Easy to carry on your arm
Cons
- Up to 75 cm according to the manufacturer: it has to be replaced at around one year
- Fitting with the seat belt needs care every time
- No rotation
Cybex Aton B2 i-Size
Budget-friendlyWho it suits: those who want an affordable shell, with a longer usage range, on an ISOFIX base or with the seat belt.
A no-frills shell, with a generous height range. For your car, check whether the base with a support leg is permitted on the seat you have chosen.
Pros
- R129 approved, up to 87 cm according to the manufacturer
- Extra, adjustable side protection
- Fitted with the seat belt or on an ISOFIX base
- Clips onto Cybex pushchairs and others, with adapters
Cons
- No rotation and no lie-flat position
- The ISOFIX base is bought separately
- The side protection element makes the seat wider towards the door
Nuna Todl Next
PremiumWho it suits: those who want a rotating seat from birth up to 105 cm, in a car where ordinary models leave no room at the front.
Among rotating seats, the Todl Next is known for its small dimensions. That is exactly why you should compare its stated length with the measurement in your car before you buy.
Pros
- Compact body for a rotating seat
- Used from birth up to 105 cm, according to the manufacturer
- The rotation helps in cars with doors that open only a little
- Can stay rear-facing across the whole range
Cons
- Needs an ISOFIX base with a support leg: check the floor
- Expensive
- Does not come out of the car like an infant carrier
Axkid Minikid 4
PremiumWho it suits: the stage after the infant carrier, if you want to keep your child rear-facing for many years in a small car.
The Minikid is often recommended precisely to parents with small cars who want to stay rear-facing. Installation takes a while, but you only do it once.
Pros
- Narrow, with an upright position that takes up little length
- Rear-facing up to 125 cm, according to the manufacturer
- Fitted with the seat belt: does not depend on ISOFIX points
- R129 approved
Cons
- More laborious installation, with anchoring straps and a support leg
- Does not rotate: putting the child in takes a bit of gymnastics
- Not for newborns
Our recommendation
For a small car, the route with the fewest surprises is: a light R129 infant carrier, fitted with the seat belt or on a base, for the first year – the Joie i-Snug 2 or the Cybex Aton B2 – and then a compact rear-facing seat, chosen after you have actually measured the space.
If possible, try the seat in the car before you buy it, or buy from somewhere with easy returns. Five minutes on the back seat are worth more than any spec sheet.
Frequently asked questions
Why does a rear-facing car seat take up so much room in a small car?
The rear-facing position needs a comfortable recline of the backrest to stop a newborn’s head from dropping onto the chest. This depth uses up lengthwise space, pushing the front seat forward. Compact models have optimised bases and angles designed for small cabins.
Can the seat be fitted on the front passenger seat?
Yes, but only if the front passenger airbag is deactivated with the key or from the car’s menu, and the vehicle manual expressly authorises this installation. A front airbag deploying onto a rear-facing seat is extremely dangerous.
What do you do if the car’s rear seat is steeply angled?
A sporty rear seat can make the shell sit too upright. In that case, choose an ISOFIX base with recline adjustment or an i-Size approved car seat that lets you adjust the angle directly from the base.
