With just under 2 months to go until my wife and I expect our second baby to arrive, I’ve been researching car seats.

I’ve already realised things will be a little tight on the back seat of my car if we have 2 car seats for an infant, toddler and a third passenger in between.

Our older daughter, Mia, is nearly 4 years old and has now outgrown her car seat, the Maxi-Cosi 2WayPearl.

For our second baby, we have the option of using Mia’s old car seat, the Maxi-Cosi Cabriofix, but it might be time to look at other options.

4 years is a long time in car seat technology!

So far we have only used Maxi-Cosi for car seat products, but Britax are another leading brand which I’ve been looking at more closely.

In this article, I’ll take a look at both brands in more detail comparing their best car seats at various stages, from infants to older children.

Detailed Comparison

Weight

WINNER – Mico Max 30

It might only be half a kilogram of difference, but the Mico Max 30 is slightly lighter than the Britax B-Safe.

Initially, you probably won’t notice a huge difference when you’re carrying either car seat from your car to your home but as your baby grows, it will get heavier to lift.

Size

WINNER – Britax B-Safe

This is tough to call as the Mico Max 30 is 8 cm longer than the Britax B-Safe which might be a slight issue if you have a small car with a small gap between the front and rear seats.

In terms of size, Mico Max 30 is narrower by a couple of centimetres which can free up fractionally more space for passengers sitting in the rear seats

However, the reason why the B-Safe wins this category is due to customers mentioning the bulky base which accompanies the Mico Max 30

It seems you only really benefit from the small size of the Mico Max 30 if you use the car seat by itself, without the base.

Safety

DRAW

Both options are safe options for your infant. The Mico Max 30 has Air Protect Superior side impact protection and an anti-rebound bar. The B-Safe also has enhanced side impact protection, as well as a strong steel frame and an impact-absorbing base.

Design

DRAW

Both car seats have some excellent features to ensure your baby is safe and comfortable in either option.

For example, the Mico Max 30 features some self-wicking fabric which helps to draw out any liquids from the baby to help them feel dry and comfortable.

The B-Safe has spring assisted recline, with auto-level indicators so you can find the right angle to install the base correctly. Let’s call it a draw!

Compatibility

DRAW

The Mico Max 30 will work with any Maxi-Cosi or Quinny stroller and the B-Safe will work fine with any Britax stroller.

Both options will work with other premium brand strollers, but make sure you check this first, as you’ll likely need adaptors and there might be some models which aren’t compatible.

Installation

DRAW

Both options use the LATCH system which makes installing the car seats straightforward, ensuring your infant is safe and secure.

Maintenance

DRAW

You can remove the covers of both car seats fairly easily, and they can be placed in the washing machine and tumble dryer for cleaning. To ensure the fabric is in the best condition it’s good practice to periodically wipe down the car seat with some cold water and mild soap.

Price

WINNER – Britax B-Safe

Depending upon the retailer, the B-Safe 35 is slightly cheaper than the Mico Max 30.

  • Very good safety features. Its “SafeCell” design goes above the safety requirements for car seats
  • Easy to install

  • 5 different colour schemes to choose from

Cons

  • Some parents find it a little heavy to carry (Mico Max 30 is little lighter)
  • Some parents have said their babies have outgrown the car seat before they’ve reached 35lbs.
  • No raincover included

Bottom Line

OVERALL WINNER – Britax B-Safe

Both options are very good car seats, and in all likelihood you wouldn’t be disappointed with either option.

Although there really isn’t much in to, I think the B-Safe just shades it. It’s a little cheaper, and its equally as well designed at the Mico Max 30, so it offers slightly better value for money.

Yes, it is fractionally heavier, but there’s not a huge difference between the two. It only presents a problem if you’re carrying the car seat a sizeable distance every day.

Detailed Comparison

Weight

WINNER – Maxi-Cosi Axiss

Although toddler car seats aren’t meant to be carried around like infant car seats, you still want something which isn’t too heavy. The Axiss is around 3kg lighter which makes it a little easier to take it out or install it.

Size

WINNER – Maxi-Cosi Axiss

Although the Britax is not as tall, in my experience car seat depth is more important as it can be an issue in small cars if the edge of the car seat is close to the front passenger seat. The Axiss is almost 20cm shorter than the Britax which is something to consider if you have a small SUV or hatchback.

However, both cars are more or less the same width.

Safety

WINNER – DUALFIX M i-Size

Although you can rest assured that both car seats are safe to use, the DUALFIX meets the i-Size requirements, and it can be used with ISOFIX to securely attach to the car. The Axiss can only be attached using a seat belt, which is normally fine, but some parents don’t use this method correctly. Just ensure you check the car seat is securely installed if you decide to buy the Maxi-Cosi Axiss.

It should be added that Maxi-Cosi now have the AxissFixx which supports ISOFIX.

Design

DRAW

Both car seats are well-designed products. They both have multi-recline positions to ensure your baby is comfortable in the car seat, and they can both rotate a full 360 degrees which makes it easy to transition from rear to forward facing, and for your child to easily get in and out.

Installation

WINNER – DUALFIX M i-Size

Although both car seats are easy to use, I personally prefer the DUALFIX because it has the ISOFIX option. Once installed, it’s slightly less hassle to strap your child into the car seat, than having to use the car seat belt which is what you’d have to do with the Axiss. Check out the videos below. You can see the DUALFIX is a bit more straightforward to use.

Maintenance

DRAW

Both car seat covers can be easily removed and cleaned in the washing machine.

Price

WINNER – Maxi-Cosi Axiss

Depending on the retailer the Axiss is generally the cheaper option of the two car seats.

  • 11 different colour schemes to choose from.

Cons

  • A little on the heavy side

Learn More

Bottom Line

OVERALL WINNER – Britax Romer DUALSIZE

I think the DUALSIZE is the better option of the two car seats. It’s slightly more expensive, but by paying that little bit extra, you’re getting a car seat which is easier to install and the option of using ISOFIX.

The only caveat is that you should check the depth between the front and rear seats of your car to check everything will fit ok before you make your decision. You shouldn’t have any problems, but if your car is very small then the Axiss might be worth considering instead.

Detailed Comparison

Weight

WINNER – Maxi-Cosi Rodifix Booster

Weight isn’t as important with booster seats as infant seats as the car seat can remain in place in the car all the time.

However, the Rodifix is 3 kilos lighter than the Grow With You, which makes things a little easier if you need to take out the car seat to clean it, or position it elsewhere. Every kilo counts!

Size

WINNER – Britax Grow With You

Although you shouldn’t have an issue fitting either car seat in most vehicles, the Grow With You isn’t as deep which gives your child a little more leg room. The height and width of both products are basically the same

Safety

DRAW

Both options should be considered safe for your child. The Rodifix has AirProtect for side impact protection and LATCH to securely install to the car. The Grow With You has two layers of side impact protection, SafeCell techology and a solid steel frame.

Design

WINNER – Britax Grow With You

The Britax wins this category as it can be used from an earlier age, from when your baby is 25lbs (where as the Rodifix can only be used from 40lbs). It’s just a better designed product overall with its ClickTight™ technology which means you can ensure your child is secure in just 3 simple steps.

You also get a cup holder, which the Rodifix doesn’t have.

Installation

DRAW

Both car seats can be installed very easily. The Britax uses its ClickTight™ technology and the Rodifix can be installed using LATCH. You shouldn’t have any trouble with either car seat.

Maintenance

DRAW

Both car seat covers are machine washable and dryer safe.

Price

WINNERMaxi-Cosi Rodifix Booster

The Rodifix is around $100 cheaper (depending on the retailer). However, just bear in mind the Grow With You can be used from an earlier age so you can use the car seat for longer.

Which one is more popular?

The Rodifix has almost 18x the number of monthly searches than the Grow With You. You’d think it would be closer as both Britax and Maxi-Cosi are two of the leading brands of car seat manufacturers.

Bottom Line

OVERALL WINNER – Britax Grow With You

You’ll likely be happy with either car seat, as both are good, safe options for your child, but the Grow With You is the overall winner for me. It’s a better designed car seat, lasting longer than the Rodifix. Furthermore, it’s more comfortable with the 2 recline positions and cupholder.

Detailed Comparison

Weight

WINNER – Maxi-Cosi Pria

The Pria is 3 kilos lighter than the One4Life. Although this will be less of an issue for older children, you’ll notice a difference when you have to take out the car seat to clean the covers or change positions.

Size

WINNER – Britax One4Life

The One4Life is 9 centimetres shorter than the Pria which will give your child a little more leg room behind the passenger front seat. The width and height of both car seats are basically the same.

Safety

DRAW

Both Britax and Maxi-Cosi pride themselves in ensuring their car seats are safe for children. The One4Life uses SafeCell technology for superior side impact protection, and the Pria uses GCell technology.

Design

WINNER – Britax One4Life

The biggest advantage of the One4Life is that it can be used up to a weight of 120lbs ,where as the Pria is only until 100lbs so you might get a year or so of extra use with the Britax car seat. It also has nine recline settings, as opposed to the Pria’s three.

Installation

DRAW

Both car seats are easy to install. With the Pria, it comes with LATCH connectors for a secure fitting to the car, and the One4Life uses ClickTight which ensures a correct installation

Maintenance

DRAW

Both car seats score well here. You can remove the car seat covers and cup holders easily. The covers are machine washable and dryer safe

Price

WINNER – Maxi-Cosi Pria

The Pria is almost $100 cheaper than the One4Life (depending on the retailer).

Bottom Line

OVERALL WINNERDRAW

I think the One4Life is the better designed car seat, with slightly better features for your child’s comfort (multi-position recline and ventilated mesh to keep them cool).

However, it is more expensive than the Pria and although both car seats are a bit bulky, the One4Life is heavier which might make things a little tricky at times (some customers have picked up on this too).

Finally, although it is an advantage that the One4Life can be used up to 120lbs, considering both car seats are only supposed to be used until your child is 10 years old, the average weight for a boy that age is 40 to 90lbs, so the Pria is more than suitable.

FAQs

Is there anything else to consider when choosing a Maxi Cosi or Britax car seat?

Make sure you check the compatibility with your vehicle. You should be ok, but you don’t want to buy a sizeable baby item only for it to be unusable.

For Britax, you can check your car’s compatibility here
For Maxi-Cosi, you can check here

Should you get a convertible car seat, or buy separate car seats?

Only you can decide. A convertible car seat is appealing, and it will probably save you money overall. However, it isn’t that practical for the first year, which is often the most demanding, as you can’t use them with strollers or travel systems.
