Britax ISOFIX car seats

Probably the biggest and best known manufacturers of child safety seats is Britax, who have one of the largest range of ISOFIX car seats for babies and toddlers. Here is the range of seats available along with information on their functions and benefits.

Cosy Tot Premium Infant Carrier

Group 0+ Suitable from birth to 13kg (approx. 0-12 months).

As well as being compatible with most Britax Travel Systems, so you can change from car to pram easily, the Cost Tot Premium has all the convenient functions and safety features you need. It can be used with or without the Britax ISOFIX base unit which is sold as a separate item (see below).

  • The Britax Cosy Tot Premium is available from ICBABY.COM

ISOFIX Base Unit

Group 0+ Suitable from birth to 13kg (approx. 0-12 months).

The Britax ISOFIX base unit (which is sold as a separate item) provides a simple 'Click and Go' attachment of the Cosy Tot Premium, and anchors the child seat directly to your car. It folds compactly for easy storage when not in use and has a 'Rebound Bar' which ensures a more secure fit and helps reduce movement for a safer ride. Latch Guides are provided to protect your cars upholstery and the front 'Foot Prop' gives greater stability. However, as we have mentioned before a foot prop is not suitable for all vehicles. (see our Can I use it? page).

Duo Plus ISOFIX

Group 1 Suitable from 9kg to 18kg (approx. 9 months to 4 years).

Probably one of the best know car seats in the ISOFIX range is the Duo Plus. It has a Universal approval (when used with a top-tether strap) and Semi-Universal without. The Duo Plus can be installed using either a 3 point vehicle harness or the ISOFIX points. The seat uses a simple push-click operation and patented 'pivot link system' which is designed to limit the amount of forward movement within the seat in the event of an accident. With a one-pull, height adjustable headrest and harness, softly padded side wings for maximum side impact protection, harness retainers which make it easy to get your child in and out of the seat and 3 recline positions, it makes a great Group 1 seat.

Explora ISOFIX

Group 1 Suitable from 9kg to 18kg (approx. 9 months to 4 years).

A Semi-Universal approved seat with improved side impact protection, a front 'Foot Prop' and Britax's patented 'pivot link system' which is designed to limit the amount of forward movement within the seat in the event of an accident. The Explora can be installed using either a 3 point vehicle harness or the ISOFIX points. Safety features include a 5 point harness with easy one pull adjustment, adjustable headrest and the 'Safe Strap' mechanism which gives you a visual indication when your child is safely secured. For comfort there are 4 recline positions for a comfortable ride, soft touch, breathable fabrics and flexible padding, and harness retainers which make it easy to get your child in and out of the seat.

Evolva 23 ISOFIT

Group 2-3 Suitable from 15kg to 36kg (approx. 4 years to 11 years).

A very safe and comfortable seat with a recline facility and the unique Britax ISOFIT system, which anchors the child seat directly to the car for superior protection. Your child is secured using your car's seat belt, however, the shape of the Evolva 23 ISOFIT correctly positions the lap belt low over your child’s pelvis whilst the belt guides position the diagonal belt safely and comfortably over your child’s shoulder.
The Britax Evolva 23 ISOFIT has gained semi-universal approval when fitted with ISOFIX fittings, but the seat can also be safely fitted in many cars without ISOFIX fittings, using just a lap and diagonal seat belt. When secured in the vehicle with ISOFIX the seat can recline for a more comfortable ride, and there is also no need to strap the seat in when not in use. The ISOFIX fittings will keep the seat fixed firmly so it will not slide around loose in your car.
