Rotate. Recline. Relax.
Enjoy easy moments with SWIVEL-GROW MAX AIR. The 360° rotation makes it simple to get your little one in and out of the car – even when your hands are full. With one-hand control, you can rotate and adjust the recline position at the same time, finding just the right angle for naps or playtime.

From newborn snuggles to school runs – SWIVEL-GROW MAX AIR grows with your child. Use the newborn insert for extra comfort in the early months, then enjoy generous seating space as they grow. The seat adapts from rearward to forward-facing and transitions effortlessly from a 5-point harness (up to approx. 4 years / 105 cm) to a high-back booster seat using the vehicle seat belt, supporting children up to 7 years (40–125 cm). Comfortable reclining positions keep them supported and relaxed at every stage. Soft comfort padding and easy harness storage make every journey safe, simple, and comfortable. One seat, years of adventures.
Protection and peace of mind for effortless travel
Experience worry-free adventures with SWIVEL-GROW MAX AIR. Certified to meet UN R129 safety standards, it allows your child to travel rearward-facing for longer — up to 4 years (105 cm) — for extra protection on every ride. The deep, padded side wings shield from impact, while the robust support leg ensures a safe and stable stand. Installation is effortless thanks to independent ISOFIX connectors, giving you peace of mind from day one. Wherever you go, SWIVEL-GROW MAX AIR keeps your little one protected every step of the journey.
A gentle breeze, every ride with AirSense™ Ventilation
Whether it’s warm sunshine or a long, sunny family trip, the active, gentle AirSense™ Ventilation of the SWIVEL-GROW MAX AIR keeps your child cool and comfortable. Mesh panels allow maximum airflow, while the built-in dual-fan system provides a steady flow of fresh air through the seat — especially helpful in warmer seasons. The ventilation can be easily powered through your car’s USB-C port or 12V socket, and USB-C charger cords are included for convenient use wherever you go. So your little one stays happy – from the first trip home to everyday adventures.
Ready for bright days, sun-safe journeys
Whether it’s bright sunshine or a gentle glare, the foldable sun canopy of the SWIVEL-GROW MAX AIR keeps your child comfortably shaded on every ride. The large coverage offers reliable protection from direct light, creating a calm, cosy space for naps or playtime. Easy to fold away when not needed, it’s always ready for the next adventure.
Buckle up effortlessly
Whether your child is forward facing or rearward facing, reclined, upright, or in the setting in between, the 360° rotation of the SWIVEL-GROW MAX AIR makes it quick and easy to get your child in and out of the car safely. So you're good to go in seconds!
Independent ISOFIX connectors
Install the SWIVEL-GROW MAX AIR effortlessly thanks to the ISOFIX connectors, which can be operated independently. You're fully in control, so they're fast and safe to connect without damaging your car's seats. And you're ready to get on with your day.
Keep them rearward facing for longer
Give your little one the best protection in the event of a frontal collision: the SWIVEL-GROW MAX AIR allows your child to be rearward facing for longer (up to 105 cm), as recommended by experts. Frontal collisions are the most common type of accident, so make sure you travel in the safest way. With a car seat in the rearward-facing position, impact energy is spread evenly across the head, neck and upper body, protecting your child from injury.
Multi-recline positions
Keep your little one happy and comfortable even on long journeys. The SWIVEL-GROW MAX AIR has multiple recline positions that you can adjust easily. With 4 forward-facing and 4 rearward-facing positions, select one that allows your child to relax or take in the view - so they're content and you can enjoy a stress-free journey.
Deep, secure side wings
Cocoon your little one with the soft, padded side wings of the SWIVEL-GROW MAX AIR, helping to keep them safe and protected from impact in the event of a collision.
Comfortable, protective headrest
Ensure optimum protection in a side collision: the V-shaped headrest, padded with soft, energy-absorbing memory foam , is specially designed to limit the movement of your child’s head, protecting their neck if the worst happens, whilst giving them space as they grow. It’s quick and easy to adjust the headrest and harness simultaneously, so your child’s completely comfortable, whatever their height. On top of that, the headrest can be adapted smoothly to ensure the ideal posture from infancy to adventurous years.
Soft performance shoulder pads
Your child's movements are reduced in a collision thanks to the soft performance shoulder pads of the SWIVEL-GROW MAX AIR. The pads bring even more comfort to the secure 5-point harness, and for those inevitable messy moments, they can even be removed for washing without having to detach the straps.
Special protection for newborns
Give your little bundle of joy the best protection, comfort and support with the specially designed newborn insert. The insert can be used for a particularly long time thanks to the extendable neck and also offers a flat reclining position (up to 75 cm). Energy-absorbing foam pads allow your baby to lie in a more comfortable, ergonomic position during those first precious weeks.
Extra-safe 5-point harness
Protect your child from serious injury by choosing a car seat with a 5-point harness (up to 105 cm). In the event of a collision, the harness distributes the force of the impact across all 5 points - the shoulders, hips and between the legs - to the seat's protective shell.
Height adjustable support leg
Install the SWIVEL-GROW MAX AIR safely in your car using the adjustable support leg. The leg fixes to your car's floor to provide extra stability and minimise tilting movements of the car seat. And an easy-to-read indicator shows you when the support leg is positioned firmly on your vehicle’s floor, making it effortless to fit correctly.
Quick-remove washable cover
Things can get pretty messy with children in the car. Whether it's a juice spillage or a bout of travel sickness, the SWIVEL-GROW MAX AIR has a machine washable seat cover that can be removed easily without detaching the harness. So you can clean up quickly and get on your way.
Growing with your child
Children develop so quickly, so adjust the SWIVEL-GROW MAX AIR to grow with them from toddler to school kid. Stay safe, whatever their size - swap easily from the integrated 5-point harness to your car’s 3-point seat belt as your little one reaches 100 cm (max. 105 cm). What's more, you can stow the 5-point harness in the backrest so it's always ready to use again. When it comes to the support leg - just fold it in and keep it in the car. You're ready to go, however big your little one grows!
Head to hip protection
Provide your child with the best protection as they grow up. The seat shell of the highback booster gives all-important head to hip support for your little one, while the belt guides ensure correct positioning of the seat belt. And the padded headrest brings safety and comfort for your child’s precious head and neck, so you can rest assured they're protected on every journey.

Frequently Asked Questions
ISOFIX or Seatbelt
ISOFIX and seat belts are two vital elements when it comes to children's car seats. Both keep the car seat secure.
In terms of safety during impact, there is no difference between ISOFIX and belt attachment, as long as they are both installed correctly - they are as safe as each other.
Weight limit or height limit first?
Car seats that have a weight limit and a height limit are outgrown as soon as your child meets one of those limits. e.g. an infant carrier might have a 13kg weight limit and an 86cm height limit, the seat would be outgrown as soon as the child was 86cm even if they were only 11kg.
What is the Swedish Plus Test?
The Swedish Plus Test is the toughest crash test in the world! The Plus Test is a voluntary additional crash test that car seat manufacturers can apply for. Plus tested car seats ensure that your child is not exposed to life-threatening neck forces during a collision. Find out more about the Swedish Plus Test here.
Can you help me install the car seat?
Every car seat purchase includes either installation at Fakenham or remote support to ensure a safe install.
