An Isofix base is a car seat secure attachment that you can use for greater vehicle safety. The base connects directly to most cars with metal clips.
You can use the seatbelt to secure your child for most car seats, but the Isofix base is easier to install.
Please note Isofix bases are heavy and not ideal for carrying around. They are best used in a car where you do not need to frequently remove them due to the weight of carrying them. Y
ou do not need an Isofix base, but some people prefer them. If you are using taxis instead of having your car, it may not be easy because of the weight of the base.
