10 Best Isofix Car Seats in 2021

Updated 29-03-2021 – Lucy Walters

Isofix car seats -what are they? According to Childcareseats.org, Isofix seats are the types of car seats that directly plug into corresponding Isofix fitting points in a car. This system eliminates the need for using seat belts to secure the car seat into place. Other additional features of the car seat are a support leg or a top tether to prevent the seat from rotating or tilting during impact.

 

Things to Consider When Buying an Isofix Car Seat

If unsure what to look for when buying Isofix Car Seats, we’ve come up with a short guide below to help. We have also rounded up our top 10 picks of the best Isofix car seats available in the UK.

 

Measure & Know your Car

The NHS recommends measuring your car properly or reading the manual to see what is compatible with your car. It is also a good opportunity to have your car checked for Isofix connectors if you don’t know how to locate them.

 

Size and Age-Appropriate

Always choose the appropriate-sized car seat for your child. Below are the car seat sizes as explained by the NHS:

  • Group 0+ – These are rear-facing and are suitable for babies up to 15 months or 13 kg.
  • Group 1 – These are forward-facing and are suitable for children aged 9 months to 4 years or weighing 9-19 kg.
  • Group 2/3 – These are high-backed booster seat ideal for 4 to 11-year-old or those weighing between 15-36 kg.

 

EU Approved

All car seats used in the UK should be EU approved. You can check this by looking for an “E” label or mark on the seat.

It features a selection of 10 colours, so you are sure to find one that suits your colour preference, or one that matches your car’s interior or exterior.

  • Built-in side impact protection

  • Ventilation system
Specifications:
Size: Group 2/3
Harness: 5-point
Dimensions: 41 x 50 x 61 cm

Best headrest safety feature

The Cybex Gold Solution S-Fix features a group 2/3 Isofix car seat that comes available in six colours: premium black, Manhattan grey, indigo blue, fancy pink, urban black, and tropical blue.

It features a patented adjustable reclining headrest, which prevents your child’s head from tilting forward while sleeping during your travels, ensuring their maximum safety at all times.

The headrest height also is adjustable for up to 12 positions, which means you can use it for longer as this adjustable feature allows it to accommodate your growing baby.

Finally, it has extra-wide and deep seat cushion ensuring your child’s optimum comfort and a ventilation system to ensure that your little one’s temperature regulation is maintained, despite long hours on the road.

6 Britax Römer Dualfix 2 R

Key features:
  • Pivot link Isofix System
  • Deep, protective side wings
  • Adjustable headrest & harness
  • Multi recline & dual-facing capability
Specifications:
Size: Group 0, 1
Harness: 5-point
Dimensions: 70 x 45 x 48 cm

Best group 0/1 impact protection system

The Dualfix 2 R is another Isofix car seat coming from Britax Römer. The name Dualfix came from the car seat’s ability to quickly and safely swivel in different directions when the car is not in motion. With the single press of a button, you can easily turn the car seat to face towards the car door opening, allowing you an easier and more convenient way of buckling up your little one for your journey. Once you’re done, it’s equally as easy to rotate the seat backwards and lock it in place. 

Another outstanding feature of the Dualfix is its pivot link Isofix system. This design ensures that in an impact, the force is directed downwards initially, followed by the vehicle seat, and then finally, forward. This system significantly reduces the risk of any head or neck injury to your little one.

This Group 0/1 Isofix car seat also comes with an adjustable headrest and harness, to accommodate your growing baby.

Comfort-wise, it has a multi-recline position, which is especially helpful on long drives, to ensure that the little one achieves a comfortable and restful sleep.

7 Cybex Gold Pallas S-Fix

Key features:
  • Integrated LSP system
  • One-hand recline function
  • One-hand adjustable impact shield
  • Patented reclining headrest
Specifications:
Size: Group 1, 2/3
Harness: 5-point
Dimensions: 43 x 50 x 69 cm

Best group 1, 2/3 impact protection system

The Pallas S-Fix is another Isofix car seat from the Cybex brand. Most of its features are similar to the Cybex Solution S-fix, which we have discussed earlier on this list. One major difference is that the Pallas S-Fix has a wider range when it comes to suitability – it covers group 1, 2/3 as opposed to the Solution that is only suitable for the 2/3 group.

The best feature of the Cybex Pallas S-fix (which is a feature also available with the Solution S-fix), is its integrated linear side-impact protection (LSP) system. This means that during a side-impact collision, the car seat is designed to reduce the forces from the impact by up to 25% when compared to other car seats in the market that do not have the LSP extended.

Another feature of the Pallas S-fix is the one-hand recline function, making it easier for parents to adjust the car seat into a sleep position with just one hand. The same one-hand technology is also implored in the adjustable impact shield, so the parent or carer can adjust it according to the child’s height and comfort level.

If you are looking for a group 1, 2/3 car seat that performs well during impact (hopefully it doesn’t happen), the Cybex Pallas S-fix may well be your best option.

8 Kinderkraft ONETO3 Car Seat

Key features:
  • Top tether belt
  • Soft, non-slip harness
  • Side protection system
  • Belt storage compartment
Specifications:
Size: Group 1, 2/3
Harness: 5-point
Dimensions: 76 x 48 x 43 cm

Best seatbelt storage compartment

The Oneto3 car seat is another group 1, 2/3 Isofix car seat from the Kinderkraft brand. Like the Kinderkraft Safety Fix, the Kindecraft Oneto3 also has a top tether belt, adding extra stability and security for the car seat. It also has the same non-slip harness, ensuring your little one’s comfort and safety at the same time.

The difference is that the Oneto3 comes with a side protection system, which provides additional protection for your little one in the cases of an accidental side impact.

The standout feature of the Kindekraft Oneto3 is its belt storage compartment for internal belts, giving a mess-free, tangle-free, and comfortable belt adjustment for you as the carer and an added safety feature for your little one.

9 Bonio Baby Car Seat

Key features:
  • 360 rotation design
  • Advanced side impact protection
  • Top tether inclusion
  • Detachable UPF 50+ canopy
Specifications:
Size: Group 0, 1, 2/3
Harness: 5-point
Dimensions: 67 x 46 x 46 cm

Best multi-stage car seat

Bonio is an Amazon retailer focusing solely on car seats and car seat protectors.

The Bonio Baby Car Seat features a 360-degree rotation design, which means that you can easily turn the car seat facing the car for a more convenient and effortless way of securing your baby into the car seat or effortlessly taking them out of it.

One unique feature of this car seat is the included detachable UPF 50+ sunshade canopy, which is perfect for keeping your newborn and younger babies comfortable and well shaded from the bright and harmful rays of the sun.

This car seat is suitable for all group sizes. It has multiple recline and headrest adjustment positions, ensuring it goes in sync with the growth of your little one.

The Cosatto Hubbub range is an Isofix car seat available in five colourful and print-rich design options. 

But this car seat is not merely about the design. It also has the standard safety and comfort features similar to most of the car seats on this list. It has side impact protection, padded armrests, tummy and chest pads, adjustable headrest, and removable and washable covers.

If you are wanting to shy away from the conventional solid-coloured Isofix car seats and want to give your car a car seat with character, you probably want to check out the Cosatto Hubbub range.
