Trying to fit three car seats across the backseat of most cars is a challenging exercise to say the least.
Many small cars are simply too narrow to fit even the slimmest of car seats. However most medium-sized cars should be able to fit three car seats if the right configuration of car seats is selected.
Bear in mind that not every trio of child seats will fit across even the largest of cars; the slimmer the model of car seat the better your chances.
One challenge is that the car seats purchased for the first two children may not have been purchased with the third child in mind. It sounds drastic, however purchasing two or three new car seats that fit into your current car is far cheaper than purchasing a massive new SUV.
Our team has done some research into the ideal car and seating features to consider when purchasing a family car. Here are our hot tips!
Tips to keep in mind before you purchase your car
In selecting your next family car the following are some key questions to keep in mind:
· What is the car’s safety rating?
· Are there any side, rear and frontal airbags?
· How many child restraints can you fit across the back seat?
· Does the car have suitable storage to allow for transporting prams, groceries etc?
Before forking out large sums to purchase your new car, firstly determine how easy it is to fit car seats and the spacing between each seat. Measure the distance between seat belt points or better still borrow some car seats and test your preferred car seat configuration before purchasing the car.
The location of the anchor bolt and how the front passenger leg room will be impacted when the car seats are fitted are also key considerations.
The location of airbags and the ability to disable airbags are key safety considerations.
