Finding a high-back booster car seat that offers top-tier collision protection without being a pain to transfer between vehicles is a constant struggle for families. While traditional stage 2/3 seats are often bulky, heavy, and awkward to store, lighter options can sometimes compromise on structural support.
The Cybex Solution G2 changes the game entirely. Designed to cover a nine-year lifespan from roughly 3 to 12 years old (100–150cm / 15–50kg), this i-Size compliant seat combines advanced safety tech with a clever, self-standing fold that makes travel effortless.
Fresh off winning gold in our Car Seat category, we put this portable high-back booster through its paces to see if it lives up to the hype.
What We Liked About the Cybex Solution G2
Packing advanced side-impact protection, ergonomic growth adjustments, and a compact fold into a seat weighing under 6kg is an impressive achievement, and Cybex has executed the concept brilliantly.
- Genius Compact Folding Mechanism: The standout feature of the Cybex Solution G2 is its ability to fold in half in a single motion. It shrinks down to a compact, self-standing unit with a handy carry handle, making it a dream for taxicabs, holidays, grandparents’ cars, or boot storage.
- Featherweight 5.8kg Build: Weighing just 5.8kg, it is significantly lighter than most high-back boosters in its class. Swapping it between different family cars takes seconds rather than turning into a back-straining ordeal.
- Patented Reclining Headrest: Cybex’s signature 3-position reclining headrest subtly tilts back to prevent your child’s head from tipping forward when they fall asleep. This keeps their head safely inside the cushioned side-wings at all times, providing up to seven times greater head safety during a side impact.
- Linear Side-Impact Protection (L.S.P. System Plus): The energy-absorbing outer shell works alongside the L.S.P. System Plus to redirect crash forces away from your child, reducing side-impact forces by up to 20%.
- Flexible Growth & Expanding Side Wings: As you raise the headrest to accommodate a growing primary schooler, the flexible side wings automatically expand to provide extra shoulder room, ensuring older kids never feel cramped.
- All-Round Air Ventilation: Integrated ventilation channels throughout the seat shell prevent heat buildup on warm summer drives, with the Plus fabric editions adding ultra-breathable mesh for maximum comfort.
- Easy ISOFIX or Belt-Only Fitting: It connects quickly using rigid ISOFIX arms for rock-solid stability, but can also be installed using just the vehicle’s standard three-point seatbelt in cars without ISOFIX points.
What Could Be Better
While this gold-winning seat sets a fantastic standard for safety and portability, keeping a few practical ownership realities in mind will help families manage their day-to-day expectations.
Not Designed for Rear-Facing
The Cybex Solution G2 is a forward-facing high-back booster built specifically for children from 100cm onwards (around 3 to 4 years old). If you are looking to keep your child rear-facing beyond 100cm, you will need a dedicated extended rear-facing seat instead.
Recline Angle Is Intended for Napping, Not Flat Sleeping
While the one-handed base recline offers a comfortable angle for resting, high-back boosters cannot recline fully flat due to vehicle seatbelt geometry. It provides great comfort for road-trip naps, but toddlers transitioning straight out of a stage-one recline seat might take a couple of drives to adjust.
Premium Price Tag
Priced between £120 and £150 depending on the fabric trim, the Cybex Solution G2 is an investment compared to basic, rigid boosters. However, given its UN R129/04 safety standards, nine-year lifespan, and folding design, the long-term value is exceptional.
Is the Cybex Solution G2 Worth Buying?
For parents, grandparents, and frequent travellers looking for a high-back booster that refuses to compromise on safety or convenience, the Cybex Solution G2 is an absolute standout buy.
It solves the age-old problem of bulky car seats by folding neatly into a third of its size, making it ideal for multi-car households, taxi rides, and airport transfers. The reclining headrest genuinely stops head-slump during long drives, and the expanding side wings ensure your child remains comfortable all the way up to 12 years old.
However, if you only ever keep your car seat installed in one primary vehicle and never intend to move or fold it, you might not use its portable features to their full potential. But for modern, mobile families, its versatility is unmatched.
Final Verdict
The Cybex Solution G2 thoroughly deserves its gold medal in our car seat category. By pairing R129/04 i-Size safety and smart side-impact protection with a lightweight, foldable frame, Cybex has created the ultimate high-back booster for modern family life. It is comfortable, durable, and effortlessly portable—a true winner for growing children.
Final Score: 9.6/10
