In Review: CYBEX Solution G i-Fix High Back Booster Seat

Is your child ready to switch to a high-back booster seat? The Solution G i-Fix by Cybex is a UN R129/03 regulated car seat offering supreme comfort with top safety features to keep your growing child safe and sound in the backseat.

What is a high-back booster seat?

A high-back booster seat is a safer way for older children to travel. High-back booster seats raise the position of your child, so the car’s seat belt can lay across their chest and pelvis area correctly. With a padded back and headrest to protect your child’s head and neck and side-impact protection, a high-booster seat is the safest and most comfortable way to travel. A high-back booster seat also gives your child a safer sleeping position when they’re snoozing on the move.

CYBEX Solution G i-Fix

The Solution G i-Fix is a high-back booster seat suitable for children weighing 15kg up to 50kg, approximately 3 to 12 years and 100 cm – 150 cm in height. What makes the Cybex Solution G i-Fix a great choice of high-back booster seat is that it combines side protection with an adjustable fit to deliver solid safety and support over years of travel.

When can my child switch to a high-back booster seat?

Before you decide to make the switch to a booster seat, you’ll need to check that your child surpasses legal height and weight restrictions. You don’t have to switch to this next size of seat until your child outgrows their toddler seat. And if they’re happy to continue to rearward face, even better.

According to Which, your child’s bones continue to strengthen as they grow older, and once they reach around 18kg or approximately four years old, or they’re taller than 105cm, you can swap to a high-back booster seat (Group 2/3 or i-Size). Group 2/3 child car seats are approved for use with children from 15kg to 36kg, which is around three and a half to 12 years of age (around 36kg).

Do high-back booster seats need ISOFIX?

Children weighing more than 22kg and taller than 125cm can use a backless booster seat, but before this age or height, child seats must be fitted either using ISOFIX mountings or a diagonal seat belt strap.

The Solution G i-Fix is installed using ISOFIX, with a fast and secure installation you can rely on. And the good news is, it’s really easy to do. Simply install the seat by simply clicking it into your vehicle’s Isofix points.

Can I use a high-back booster seat in the front seat?

High-back booster seats can be used in the front of the car, but we always advise installing them in the back. It’s the safest position in the car, especially if there is a passenger airbag in the front.

Comfort that is ready to protect

The Solution G i-Fix is Cybex’s first high-back booster to offer a one-hand seat recline for first-class relaxation on the road. With a car seat this comfortable, sleep is pretty much guaranteed. The booster’s patented 3-position reclining headrest supports stop your child’s head from falling forward when they doze off. Their head and neck stay in a safe position, protected by the car seat as they sleep.

Linear Side-impact Protection

The Linear Side-impact Protection System Plus can divert up to 20% of side-impact forces away from your child compared to a seat without an L.S.P System. The seat’s energy-absorbing shell safely neutralises the force, keeping your passenger safe in their seat in the event of a crash.

Adjustable high-back booster that supports your growing child

Since they’ll need booster seats from 3 to 12 years of age, you’ll want to invest in something that will grow with your child. The Solution G i-Fix has a height-adjustable headrest and flexible side wings, so your child can enjoy a tailored fit. The seat’s fabric covers are machine washable at 30°, so you can keep it looking and smelling box fresh.

Air Ventilation System

The Solution G i-Fix has an air ventilation system to keep your child cool, making it ideal for long car journeys. Cooling air flows through the car seat, carrying away heat and lowering the seat temperature to keep your child comfy and happy.
