What is a Group 1 2 3 Car Seat?

The value for money offered by this Group of Car Seats goes without saying really: buying a new Car Seat as your child(ren) reaches each stage would indeed involve a lot of expense. Increasing in popularity, Group 1-2-3 Car Seats are 'Multi-Stage', or 'Multi-Group' car seats. These cover a broad variety of ages, adapting and adjusting as your baby gets bigger.

If you need a seat for your child aged between 9 months right up to 12 years, this is the group for you. As this is such a lengthy period, these car seats have no doubt been built to last. The Car Seats in this group are on the whole sturdier and possibly less easily transferable between vehicles. This is because they are designed to last and act like a permanent fitting in your car.

Kiddy Guardianfix 3 Car Seat

Kiddy Guardianfix 3

Kiddy Guardianfix 3 Car Seat

Thank goodness for the Kiddy Guardianfix 3 Car Seat. This suit of armour is designed to adapt and grow with your child. After growing out of Group 0+, this seat will give you an easy transition into the next stages of your child’s life. Additionally, the specially designed the easy-to-clean, durable materials will allow you to wash away any mess. These removable seat covers are machine washable, meaning no hand-washing fuss for you! 

Kiddy's fantastic impact shield is brilliant for small children as it will absorb energy from any knock or collision. ISOFIX or 3-point belt connections, the choice is yours! The easy to flip-out ISOFIX arms allow the seat to stay more-than securely installed into your vehicle. Suitable from 9 months to 12 years, this Group 1/2/3 seat offers everything a growing child needs for maximum comfort throughout every long car journey.

When is it time for a bigger car seat?

Group 1 2 3 Car Seats are recognised as being one of the more popular choices these days. The indicators for moving on to this size car seat from Group 0+ include when a child's weight is around 13-14kg and therefore no longer within the weight limit for this group. However, Group 1 2 3 Car Seats start from 9kg, so if you wanted to get one a bit earlier, you could!

Also, if they have reached the maximum height for the seat or the adjustable harness doesn't fit anymore as their torso is too high - remember that the harness should be positioned at 2cm above your nipper's shoulder. As well as this, you should move your baby onto the next car seat group when you notice that when seated, their head comes up higher than the protective headrest of the seat (or their eyes are level with the top of the headrest).

Purchase Group 1-2-3 (9-36kg) child car seats for fantastic prices from all the best brands like CosattoMaxi Cosi and BritaxBuggyBaby offer free and fast delivery with a dedicated customer support team should you need any help.
