ULTIMATE SAFETY
Give your child maximum protection on every journey. The 5-point harness can be used right up until your little one reaches 105 cm (max. 22 kg), meaning you can rely on the ADVANSAFIX PRO to keep your little one safe for longer. Plus, it's been developed and approved to the latest i-Size standard (UN R129), and is equipped with advanced safety features. Rest easy, the SICT, XP-PAD and SecureGuard work together to provide the best possible protection in any accident.  

COMFORT AND FLEXIBILITY AS THEY GROW
Give your little one a comfortable ride - even when they're not so little anymore! Just like a faithful cuddly companion, the ADVANSAFIX PRO brings maximum comfort for every stage of childhood - from toddler to tween. No hassle for parents - the spacious, softly padded seat and headrest adjust effortlessly so you create the perfect fit for your child. Switching from 5-point harness to your car's seat belt means there's no need to buy another car seat - the ADVANSAFIX PRO protects your child from 15 months to 12 years. Busy day of adventures? Recline the seat at any age so even your bigger kid can nap easily in an extra-comfortable sleeping position.  

PEACE OF MIND FOR PARENTS
Relax: there's no need to buy a new car seat as your toddler gets bigger. The lightweight ADVANSAFIX PRO grows and protects your little one throughout their childhood, making it a faithful companion on every journey. Effortlessly adjust the headrest and harness simultaneously, so you're always ready to get out and about - even if your darling's had another growth-spurt. And when your child's big enough, switch from 5-point harness to 3-point seat belt with the FLIP&GROW function.  

 

EXTRA-SAFE 5-POINT HARNESS

Protect your child from serious injury by choosing a car seat with a 5-point harness. 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.

SOFT PERFORMANCE CHEST PADS

Your child's movements are reduced in a collision thanks to the soft performance chest pads of the ADVANSAFIX PRO. 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.

TAKING IT EASY WITH EASYRECLINE

Make every journey relaxing - for you and your child - with the Easy Recline function of the ADVANSAFIX PRO. Suitable throughout childhood, choose the recline angle without having to readjust the installation. You can even adjust the seat while your little one's clipped in, so they can sleep more easily - and you can enjoy a relaxing drive.

ADVANCED SIDE IMPACT PROTECTION – SICT

Protect your little one in the event of a side collision with superior side impact protection. The Side Impact Cushion Technology (SICT) minimises the distance between the car and the car seat, reducing the force of an impact by up to 40%*, and directing the forces away from your treasure. Simply adapt the SICT to the side of the car seat closest to the door, and you know you're giving your child the very safest ride.

COMFORTABLE, PROTECTIVE HEADREST

Ensure optimum protection in a side collision: the V-shaped headrest 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.

FLIP&GROW WITH YOUR CHILD

Children develop so quickly, so adjust the ADVANSAFIX PRO to grow with them from toddler to tween with the FLIP&GROW function. 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 / 22 kg). You're ready to go, however big your little one grows! What's more, you can stow the 5-point harness in the backrest so it's ready to use again if you plan on another bundle of joy.

PROTECT THEIR NECK AND CHEST

No matter how carefully you drive, you need to safeguard your toddler from other road users. Protect your little one's precious neck in a frontal impact with the shock-absorbing foam XP-Pad. In an accident, it reduces an abrupt forward head movement by up to 30%*, preventing you child's chin from hitting their chest. The XP-Pad even makes every journey more comfortable - it adds a comfortable padded edge so the seatbelt won't cut into your child's delicate skin.

PROTECTION IN ALL THE RIGHT PLACES

Your natural instinct is to shield your child from any harm. Protect your little one in the event of a frontal collision with the SecureGuard. Adding an extra fourth contact point to secure the lap belt safely across your child's pelvis - rather than their delicate tummy - reduces abdominal forces by up to 35%*. And since it doesn't restrict their movement, your growing kiddie will still be comfortable throughout your journey.

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.

 

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 ADVANSAFIX PRO 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.

 

INDEPENDENT ISOFIX CONNECTORS

Install the ADVANSAFIX PRO 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.

 

REDUCE THE RISK OF INJURY

Give your precious bundle greater stability and security if a collision occurs. The sturdy Top Tether minimises any rocking movement of the car seat during an accident, reducing the possibility of harm to your child's head and neck.

Great Product for noise reduction in Auto Use.
Model: 36 SqFt(3.4 SqM)
I use this on many builds to dampen the metal echo in cars, vans, and trucks. Just one sheet in the center of a body panel is a huge difference maker. You can also cover the entire surface and get added insulation value. The noise is greatly depleted and it's easy to install with a roller tool. Looks Great when done. Good Product I will use again!

Makes For Quiet Rides
Model: 10 SqFt(0.95 SqM)
Comparable quality and performance to name brand competitor. It sticks on strong, easy to apply, and does make a difference in sound reduction. Turn your hollow shell sounding vehicle panels into solid sounding walls.

Must for subwoofers. True 2mm spec. High quality.
Model: 36 SqFt(3.4 SqM), Model: 36 SqFt(3.4 SqM)
Let me start of by saying WOW! This made a huge difference in the SQ of my L7S pushing 930w rms. Before I had major rattles in my 2020 Honda Civic SI. Taking the time to do this to my trunk and Lid made me realize just how loud my subwoofer actually is. It literally eliminated the rattles throughout my whole car. I still plan on doing this to my doors and rear deck but once I upgrade the speakers. I still have half of the box just doing the trunk and lid so 1 box of 36sf will be enough for most of the areas that need to get done. You may need a little more overall. This is true 2mm spec. Very sticky and easy to apply. It just take time to finish the work correctly and roll it down. It is not as heavy as I thought it was going to be. The size of the sheets are perfect for what you need to do. The value is on point for the quality. It does not rip very easily but you can cut it to size without any problems. Again, This is a must buy for anyone who is pushing 1000w rms or more.

Quality product you
Model: 18 SqFt(1.7 SqM), Model: 18 SqFt(1.7 SqM)
Summary: Great quality product, priced right. Cuts and installs easy-follow the instructions people!! PRO TIP-you don’t need to cover every square inch. OVERKILL!! Think about it-when a bell rings you could put your fingers on the edge and silence it right? Same rules apply here. A strip or square will isolate the vibration and notice when placed correctly— knock on the surface and see what vibrates or what part makes the loudest drowning and that’s a good clue of where you should put a piece of this…unless you’re trying to use it for temperature insulation no need to go ape on it. If you look at the bottom of a stainless steel sink, it’s got a stripe or a small sticker of insulation that keeps it from rattling. You can do that here. What’s important to note is the instruction specifically say use a roller to roll the ribs out until it’s smooth that way you’ve got maximum adhesion. I see a lot of pictures and videos from people that finished their install and didn’t follow this simple instruction. It makes sure that it’s stuck down before you put all your paneling and carpet back in and it’s a small step with a cheap wooden roller it’s easy. I’ll say the installation with this product is a breeze. You can use sharp scissors or a blade. It does get gummy after a while, and you may need to clean off your blade or your scissors, but it cuts very well and the ribs make it easy to size in space the thickness is fantastic and the backing paper comes off quite easily. I’ve done lots of installations with Graphics emblems you name it and this product is very easy to use and represents good value.

Good stuff !
Model: 36 SqFt(3.4 SqM), Model: 36 SqFt(3.4 SqM)
This is an excellent product. Easily moldable, cuttable with good scissors or razor knife, very sticky, works great. This pack was enough to do all 4 doors on a crew max truck, and I went wild on the fronts. I used 9 peices on each rear door which was just enough, and the rest on the fronts. I doubled up layers and even used some on the back of the door panels. If you follow the instructions and dont go wild you might even have extra left over. It works just like you would imagine. Without doing the entire cab there will still be road noise but this helped noise, better audio, no buzzing door panels, terrific improvement. It is kind of heavy, so extra weight is added to truck, but that really isnt a bad thing. It is noticable but in a good way. Get it. Use it.
