Maxi-Cosi FamilyFix Car Seat Base

Product information

The Maxi-Cosi FamilyFix car seat base features an ingenious light and sound LED display to rule out any incorrect fitting, ensuring absolute safety.

The first green light signals the correct fit of the base onto the IsoFix anchoring points in the car.

The second light confirms that the support leg has been clicked into the right height and position.

Finally, the third green light gives parents the all-clear that the Maxi-Cosi Pebble (Group 0+, sold separately), Maxi-Cosi CabrioFix (Group 0+, sold separately) or Pearl (Group 1, sold separately) car seat has clicked securely onto the base.

Three green lights and one beep tells you you’re safe to go!

Compatible with Maxi-Cosi CabrioFix, Pebble and Pearl infant carriers and car seats. 


Under no circumstances should a car seat be used on a passenger seat where there is an airbag.
Correct fitting of all car seats and boosters is of paramount importance to make them most effective in the event of an accident.
Not all car seats or bases fit all cars and it is important to check for fitting suitability on all cars you intend fitting the seat to, as well as re-checking if you change your car.
Always read the instruction booklet which comes with your car seat to achieve a safe and correct fitting, retaining the guide for future reference. We recommend fitting your car seat in advance of first using it.
We recommend that babies shouldn`t be left in Group 0/0+ car seats (infant carriers) for prolonged periods.


Please make sure that you check the car seat or base you choose is suitable for your car before ordering.
Some of our shops offer a car seat fit test, where a Nursery advisor will test the display model in your car to check that it will fit properly. Please contact your local shop to see if this service is available. Alternatively, please contact the car seat manufacturer who will be able to advise whether their model will be suitable for your car.

Q & As

Rated 4.9 out of 5 by 48 reviewers.
Rated 5 out of 5 by Ease & convenience for a very busy Grandma This product is well-worth its high-end price tag. No need to move a whole baby car seat with all its elements from one car to another. Keeping it in another car ensures that the baby is secure in either vehicle. All that needs to move is the chair/basket - and the baby of course!! 15 September 2015
Rated 5 out of 5 by Excellent Bought to use for a short time as grandchild staying - very pleased as it secures the seat safely. It was more expensive that other bases but is worth the extra money as the whole unit makes the seat feel safe and secure. 04 August 2015
Rated 5 out of 5 by maxi cosy family fix Our daughter bought a child seat that uses this as a base. To avoid having to move the whole unit from car to car when we had the babe we bought this base. My memories of moving seat and infant when our children were young was that it was a nightmare having to strap the seat in with the safety belts and it cost me a lot of serious back problems for years to come. This system is a doddle and I feel much more confident of its safety. Not cheap but well worth it. 07 July 2015
Rated 5 out of 5 by Simple and effective The family fix car seat base is simple to set up and install, it takes less than 5 minutes to move between cars. Once installed, it makes fitting the car seat so quick, easy and stress free, simply drop it on, line up the fixings and in it locks. The base even tells you all is secure for added peace of mind. The family fix base is compatible with the new born & toddler size so works out great value for money. 31 March 2015
Rated 5 out of 5 by Great product! This base is excellent. Initially we bought a different one which didnt have the isofix- we found that it didn't seem Sturdy enough. This one however is solid. And the sounds it makes when correctly configured, give u peace of mind. Also it is easier to get the carseat off the base in comparison to the previous maxi cosi model. Definitely recommend! 03 March 2015
Rated 5 out of 5 by I'm more comfortable too As Granni to Oliver, I don't need to use the car seat that often - so had been 'making do' with seat belt security. However, I never felt that comfortable doing that and so decided to buy the seat base. It is so easy to use, the green light system gives me assurance and so Oliver and I are both more comfortable knowing he is safe. You really can't put a price on safety of your precious grandchild, but already I have used it more than I thought I would and so it becomes better value for money 18 September 2014
Rated 5 out of 5 by easy to install Arrived quickly and easy to install, pleased with this product and was price comparable to other retailers 09 September 2014
Rated 5 out of 5 by Invaluable Worth it's weight in gold for both convenience & peace of mind ( it beeps to ket you know the seat is attached securely) 10 August 2014
