Best Buys 10 Of The Best 10 best performing 1/2/3 car seats The top-performing Group 1/2/3 car seats that will grow with your child from 9 months to 12 years, chosen from our rigorous MFM tests and reader reviews 1 of Ad break But first, a quick guide explaining what a 1/2/3 car seat actually is… There are currently multiple car seat groups in the UK that range from Group 0/0+ (newborn) to Group 2/3 (4-12 years). While many parents do it, buying a new car seat for every stage is very expensive. However, there are also combination, or multi-group car seats that cover a range of the groups. A Group 1/2/3 combination car seat is suitable from 9kg to 36kg, which is roughly 9 months to 12 years. More recently we have seen the emergence of Group 0+/1/2/3 seats, meaning they can be used through all stages, from birth to around 12 years. While multi-stage, particularly Group 1/2/3 seats are increasing in popularity among parents, it is worth bearing in mind a few pros and cons of the multi-group seat. Built to last, but costly - These seats are usually built to last, meaning they are, on average, more expensive than a single group car seat. Still, they are an investment and will save you money in the long run. Heavy and less portable - The 1/2/3 seats are also more likely to be heavier and less portable than other car seats, and won’t be easy to move out of the car to the home. It also isn't compatible with a buggy to create a travel system. Not i-Size compatible - Group 1/2/3 car seats have traditionally been forward facing from 9 months, but this trend is changing with the new i-Size laws (more on this below) introduced in 2013 and UK regulations implemented in April 2015. In a few years (thought to be 2018) all new infant car seats sold in the UK will have to be i-Size (ECE R129) seats. That means children will have to sit rear-facing until they are at least 15 months, eventually phasing out forward-facing from 9kg or 9 months car seats. You can find out more about i-Size legislation here. Cosatto Hubbub, £185This Group 1/2/3 car seat is ideal if you've got a mini Houdini on yours hands as it comes with an integrated 5-Point Plus Anti-Escape System. A protective 'waistcoat' that sits just under the armpits and goes around the back and over the shoulders of your little one, it means there isn't a gap for kids to wriggle out of the harness. Our reviewer and his sons tested it out, and the boys did find it almost impossible to get out of the harness. But it's worth noting it's not perfect, according Cosatto in its tests 9 out of 10 children couldn't wriggle out of their harness, so be sure it's fitted tightly before driving. As a Group 1/2/3 forward-facing car seat the Hubbub also comes with Universal ISOFIX, side impact protection, 6-position headrest, 5-point safety harness with quick-release button. Check out the complete review of the Hubbub here.

The ‘HERO’ safety system harness is one unit consisting of shoulder pads, belts and an inner headrest. It is said to provide optimum safety and comfort for the head, neck and shoulders whilst preventing the belt from twisting or slipping. Our MFM mum reviewer was "very confident" when strapping her little boy into the Young Sport HERO and said he found it "very comfortable."

Compare deals from top retailers MadeForMums Preferred Partner Don't forget these important car seat safety guidelines: 1. Car seat law - you need to use a car seat to transport your baby around in a car. Read the latest law update and the exceptions 2. Safety - should be your priority when choosing a car seat, not looks or budget bargains. While price is important, and not actually an indicator of how safe it is, don’t settle for second best – or secondhand. 3. How it fits in your car - not all car seats fit in all cars, and incorrectly fitted seats can be dangerous – so make sure you get it professionally fitted. Some manufacturers also offer a quick online checking service, such as Britax’s Fit-Finder or Maxi-Cosi’s car fitting list. Have your car’s make, model and year of production close to hand for fast checking. 4. ISOFIX - This is a type of fitting, which makes it easy to install your car seat correctly into your car. However, not all cars have ISOFIX - so check your car is compatible before buying. And remember, some ISOFIX car seats can also be fitted into a non-ISOFIX car with a seat belt. Want more car seats?
