Safety is the most important feature to consider when choosing a car seat. Whether you are buying the first seat to bring your newborn home, a portable seat to move between vehicles or a versatile seat that will grow with your child, it’s important to choose the safest product. One of the best safety options for car seats is an ISOFIX car seat.

With all the great options on the market, it can be difficult to find a great balance between safety, comfort and affordability. Take a look at all the best rated ISOFIX car seats, compare and contrast your favorite choices and have all your questions answered with a helpful FAQ list.



The International Standards Organization, or ISOFIX, is an international set of regulations that helps ensure only the safest car seats are sold. The term ISOFIX is far more common in Europe, so you may not see American car seats advertised as ISOFIX products.

ISOFIX car seats use the metal brackets at the base of the seat to secure to your vehicle rather than using a standard seat belt. These specially designed brackets can keep your car seat more firmly in place. Most cars have been equipped with ISOFIX fittings since 2006.

In the USA, these fittings are more commonly referred to as the latch system. There are several different variations of car seats that use the metal connectors, and some are easier to use than others. Compare each car seat and connection system before choosing the best car seat for your family.

How Do I Install an ISOFIX Car Seat?

Check your individual car seat for detailed instructions, and be sure to read the entire owner’s manual. ISOFIX car seats use a variety of connection techniques. Most use an adjustable belt with two latches. This system is the most common, but it is also the most difficult to tighten properly. You want to make sure your car seat can’t move more than 1 inch in any direction.

Other ISOFIX car seats have upgraded their system and use a push-to-connect feature. Simply line the two arms up with the metal brackets in your seat and push firmly until you hear a click. Premium car seats have this handy feature, which makes installation far easier. However, it also adds weight to your car seat, so it may not be the most convenient option if you are looking to carry your car seat or travel on an airplane with it.

Inexpensive options have a latch system that can be difficult to install, and they don’t often include additional convenience features. You’ll need to rethread straps in order to remove the car seat cover or adjust the car seat, which can be time-consuming. Affordable car seats are typically more lightweight, but they don’t have as much padding.

Expensive car seats are designed to be easier to install and more comfortable for your child while having added safety features. However, they can be bulkier and heavier, and they don’t always offer a wider weight range.

The Graco 4Ever is an incredibly flexible car seat that will keep your child safe for years to come. It’s the most expensive all-in-one seat, but it offers more options, a better reclining system and comfortable straps.

Whether your child is 10 days or 10 years old, you’ll have peace of mind with the Graco safety features. The infant and toddler seat has side-impact protection, and you can use the product as a backless booster seat.

Choose from a variety of understated color options and enjoy the additional padding for your infant’s head and the seat’s straps.
