Steer yourself in the direction of one of these car seats, to keep little ones safe on every journey
A good car seat is one of the most important – and likely one of the most expensive – purchases you’ll make once you know you’ve got a baby on the way. It can also be one of the most confusing things to buy, with dozens of makes and models on the market and some confusing safety regulations to consider.
We recommend that you spend a lot time researching a car seat. After all, it’ll keep your baby safe on every journey. You’ll need one from the very first day of your baby’s life, so you can bring your new bundle of joy home from the hospital. While plenty of baby equipment can be bought second-hand, a car seat is one purchase that should be brand new - so you can be certain it’s never been in an accident. If it has been - or you suspect it has been - it should be replaced immediately.
A car seat is designed to absorb shock in case of a crash, and to hold your baby snugly but comfortably in place while you’re driving. They’re also required by law. In the UK, children must use a car seat until they’re 12 years old or 135cm tall, whichever comes first. Car seats must be rear-facing until your child is more than 15 months old – after that, they can be forward-facing, but rear-facing seats have been proven to be safer, whatever the age of your child.
Car seat sizes are either based on your little one’s height or weight. Only EU-approved height-based or weight-based child car seats can be used in the UK. Height-based car seats have a label showing a capital ‘E’ in a circle and ‘R129’. Weight-based car seats have a label showing a capital ‘E’ in a circle and ‘ECE R44’. Make sure your new purchase meets one of these safety standards – the height-based R129, also referred to as iSize, is considered the safest, and we’d recommend picking this regulation.
Don’t forget to check your new seat fits in your car. Manufacturers usually have fitting lists on their websites, so you can see if the seat you like is compatible with your car’s make and model. Car seats can either be installed using a seat belt or ISOFIX. The former will work in any car with a three-point belt, while ISOFIX car seats have anchoring points on their base which fix into the anchorage points inside a compatible car. All cars manufactured after 2014 have ISOFIX.
The rest is personal preference. Some car seats are standalone seats, but others are part of a ‘travel system’, enabling you to swap car seats using one installed base as your baby grows, and pop the car seat on your buggy when you’re out and about. We join many parents in recommending a swivel seat. This saves your back and your patience when you’re popping your baby in and out of the car every day.
Good car seats are not cheap but it’s one of those bits of baby kit that is worth spending as much as you can afford. While some models come in at more than £500, we’ve also got a few more affordable options in our round-up.
Our three-month-old and 18-month-old testers put each car seat through its paces for comfort and durability, while us adults compared each car seat for ease of installation and adjustability.
Every single product featured in an IndyBest review has been tried and tested by one of our expert testers. Sian Lewis is an award-winning journalist who has written for IndyBest since 2020. With years of experience of testing products aimed at parents and children, Sian has previously brought readers her verdict on the best running buggies, kids’ attire and more.
This is the world's first rotating car seat approved for use up to six years old (or up to 125cm or 22kg, whichever milestone your child hits first). Travelling rear-facing has been proven to be safer than forward-facing, but if your child prefers to face forward after 15 months, this chair is easy to swivel with one hand. It also has reclined positions for nap time, extendable leg space as your kid grows, and is lightweight enough to carry comfortably. This is our top choice for an ISOFIX model.
Joie’s well-padded seat for toddlers can be used from 15 months to 3.5 years – perfect for when your child outgrows a baby seat. We like the quick-to-adjust headrest and harness and there’s good side protection. On top of that, there’s even a little cup holder for snacks. We found it a little fiddly to adjust the seatbelt, and this seat doesn’t recline for naps, but it is still a well-made yet relatively affordable option. The removable cover is easy to wash, too.
However, this won’t work for newborns, and it doesn’t swivel, so it’s a little awkward to unbuckle your child at the end of the journey.
Thule offers up the best of solid, safe Scandinavian design in the elm car seat. Designed for growing children, it boasts an adjustable headrest, deep side-impact protection, and comfy padding to keep your little one snugly in place. We found the ISOFIX installation easier and more intuitive than most car seats on test, and we liked the fact that you can text Thule for installation advice. This seat swivels, has good reclining options, and has a five-point seatbelt. The only drawback is that it won’t work for kids older than three. While not the cheapest option, the elm feels like it offers one of the safest and most secure rides on the market.
If you don’t want to faff about with a different car seat every few years, Avionaut’s sky 2.0 is a great choice – it can be used from day one until your child is six. This design should last your family for years –if you swap to a toddler cushion as your baby grows they can keep travelling rear-facing, which is proven to be safer. This capacious seat is easily installed using a seatbelt, and it passes the Swedish Plus safety test, which goes above and beyond the R129. The seat also comes with a 10-year warranty, plus free replacement (for two years) if you’re in an accident. However, it doesn’t swivel, a feature you might expect at this price.
New this spring, this is an update of the popular aerofix 2.0 car seat. The airflow version has been redesigned with a breathable mesh structure to help regulate your baby’s temperature. During testing, we found it was ideal for keeping babies cool during a heatwave or for taking with you on holiday, and it will help keep little ones cosy in the cold, too. Of those we tested, this seat was also one of the most lightweight to carry and can be used rear-facing or forward-facing once your child is more than 15 months old. There are adjustable angles for nap time, and this seat comes in eye-catching pastel colourways - but we suggest you stick to the grey or black to avoid stains.
Maxi Cosi’s 360 range is popular for good reason – these lightweight, swivelling designs are easy to click in and out of the ISOFIX base and can be turned one-handed, which is very helpful when you’re wielding an energetic older baby in and out of the car. An update to the popular pebble 360 pro, the pebble 360 Pro2 now includes a mesh inlay, which is great for regulating your baby’s temperature. During testing, this was one of the seats we rated most highly for comfort and ease of use. It is also certified for use on an aeroplane, so your baby can travel safely in their own car seat. However, like the Inglesina Darwin infant recline below, this car seat won’t work for children older than 18 months, so you need to buy a whole new car seat after just a year and a half.
This car seat is perfect for the day you bring your child home from the hospital until their first birthday. This seat has been designed with newborns in mind, with angles that help them lie flat in a soft and comfy bamboo liner and the seat is easy to swivel when you’re popping your new arrival in and out of the car. After your baby is 12 months old, you can swap out to a bigger seat from the Darwin range and use the same ISOFIX base, but it’s expensive to buy twice when other products will adapt to babies as they grow.
The Doona X is a rear-facing seat that converts into a stroller, so there’s no need to transfer (or wake up) your baby when you arrive somewhere – you can just pop out the wheels from the car seat and go. The design is sleek and has plenty of great safety and comfort features – a five-point harness and padded sides keep your little one snugly in place, and we liked the adjustable headrest and faux-leather-padded handlebar. The newborn insert is made from bamboo and is lovely and soft (and, importantly, easy to wipe and wash), so it’s nice to use from day one. This is a clever, go-anywhere model that we keep spotting at airports, too.
In our full review of the Doona X, we found that it’s very heavy. At 8.3kg, this might not be one for single parents, and it’s a problem that will get worse as your kids grow heavier. It also doesn’t rotate.
Launched this February, the new lightweight ARRA flex from Nuna is a great choice for babies. We thought this was one of the comfiest seats on test, guaranteeing a very cosy baby. There are three recline positions to help your little one get off to sleep and details such as a leatherette handle, removable canopy and a Merino wool insert that feels lovely and soft to touch. If your baby is fussy about car seats, this one might just help them relax and drop off to sleep. The ARRA flex is suitable for newborns and is compatible with travel systems, so you can pop it on a compatible pushchair when you’re on the go.
That said, it can only be used up until your newborn is 2 years old. It can’t rotate, so while you can fix it to a pushchair, it might be fiddly to remove from the car.
Car seats can be painfully expensive but Ickle Bubba proves you can have a safe and easy to use ISOFIX design for less than £200. This swivelling design can be fully rotated and technically can be used until your child is 12 years old. However, we think kids over the age of four or five would feel restricted. We found the ISOFIX base simple to install, and we liked the fact that your baby can be rear-facing until they’re four years old.
Proving car seats don’t have to cost the earth – or look boring – the zoomi is bright, fun, functional, and costs less than £100. Seven bright designs, ranging from foxes to unicorns, will keep kids interested during car trips. The company claims that the different inserts mean that this seat is suitable for little ones aged from nine months to 12 years. However, those aged less than 15 months are not advised to face forward, and we think it will only fit kids up to around five. The harness and adjustable headrest are great, too. This is a good budget seatbelt option for children who are more than 15 months old.
Fran Vaughan, managing director of Ickle Bubba, answered our questions:
Car seats used in the UK must adhere to two standards: ECE R129, which is the latest regulation, or ECE R44. You can choose which type you want to go with.
Car seats that adhere to ECE R129 are called iSize seats. These seats are fitted against your child’s height and ensure children are rear facing until they’re 15 months old. Rear-facing travel is optimal for babies and children because it offers more protection for their necks if a collision does occur. All iSize seats have Isofix as standard and have side-impact collision testing as part of the approval process.
ECE R44 seats are fitted based on your child’s weight. Many allow your child to face forward from 10 months, and some allow you to fit the seat using just a seat belt. This is handy if your car doesn’t have Isofix fixings. These seats aren’t required to have side-impact collision testing as standard.
Isofix is a way for a car seat to be secured into your car. It’s designed to make fitting the seat easy, as research shows many older car seats are fitted incorrectly, which makes the seat unsafe. Car seats with Isofix have connectors that come out of the back of the seat and slide into your car’s Isofix fitting points. Many seats then have a green indicator or lights (usually in the base) to let you know the seat is securely fitted in place. Isofix anchors the car seat to the chassis of the car, locking it in place more securely than if you were to use just a seat belt. Often an additional top tether or support leg is then used to stop the seat tipping forward.
Figuring out when your child is ready for the next size of car seat is relatively straightforward. With iSize seats, it’s based on height:
For the R44 seats, seat sizes are based on weight and go up in groups:
Your child may not fit the seat based on their age. It really depends on their weight or height, so it’s important to measure or weigh your child to check.
Multi-group seats are great for those who have different age children using the seat, such as childminders or grandparents.
It’s generally much safer. When babies are sitting in a rear-facing car seat, the shell acts as a protective shield and absorbs any force, should there be an accident. As a result, the impact would spread over the whole area of the child's back, neck and head, putting significantly less strain solely on the baby’s neck.
Legally, kids should only turn forward-facing once they weigh 9kg and at this stage they will sometimes require a new car seat, depending on the model. However, many studies have recommended children should stay rear-facing for longer than the legal requirement and in some cases up to four years old.
When it comes to safety testing, car seats in the UK have to conform to one of two standards: ECE R129 is the newest Europe-wide regulation, known as i-Size. This runs alongside the existing ECE R44 regulation, and parents can choose either seat type to use.
i-Size uses your child’s height for fitting, and in order for a car seat to be i-Size compatible, it must be used with an Isofix base. Other car seats that far under the ECE R44 regulation are split into groups based on weight.
Monitor the weight and height of your child regularly, to ensure you are using the correct car seat. Don’t rely on visual indicators only.
Check that it meets ECE safety standards. A sticker is normally located on the car seat to indicate this. Also, make sure the car seat is compatible with your vehicle. Most are universal fitting, but it's best to check before you purchase.
All of our top-rated car seats are safe and comfortable but the BeSafe beyond 360 is the perfect all-in-one chair that keeps your baby rear-facing until they are six years old. Meanwhile, Nuna’s ARRA flex stood out for babies and Joie’s elevate was our top budget pick.
