Yes, specific rear-facing-only models like the Joie i-Prodigi and i-Spin Safe have passed the Swedish Plus Test, proving they handle high crash forces.
Many parents look for the Swedish Plus Test mark because it represents the highest standard of neck protection currently available. While Joie is a massive brand with dozens of seats, only a select few of their car seats hold this specific certification. This is because the test is so difficult that practically any seat allowing forward-facing travel will fail automatically due to neck force limits.
Knowing which specific models carry this badge helps you make the safest choice for extended rear-facing travel. Below, we break down exactly which Joie seats passed, why others didn’t, and what this means for your child’s safety on the road.
Understanding The Swedish Plus Test Criteria
The Swedish Plus Test is voluntary and handled by the VTI (Swedish National Road and Transport Research Institute). It is not a legal requirement for selling seats, but it is highly respected by safety advocates. The test differs from standard EU regulations (R129 or R44) in two main ways: higher crash speeds and strict neck load limits.
Standard approval tests focus largely on keeping the dummy contained within the shell and limiting chest deflection. The Plus Test focuses almost entirely on the child’s neck. In a frontal collision, the neck is the most vulnerable part of a young child’s body. The Plus Test sets a limit of 1220 Newtons of force on the neck of a 3-year-old dummy. If the sensors record anything higher, the seat fails.
Most forward-facing seats exert forces well above this limit during a crash. Consequently, no forward-facing combination seat has ever passed the Swedish Plus Test. This is why you will only find this gold seal on seats that force the child to stay rear-facing.
Joie Car Seats Swedish Plus Tested – The Approved List
Joie has expanded its lineup to include seats that meet these rigorous Nordic standards. If you are specifically hunting for a Plus Tested Joie seat, you must choose one of the following models. These seats are designed purely for rear-facing use and do not allow you to turn the child forward.
Joie i-Prodigi
The i-Prodigi is Joie’s flagship extended rear-facing seat. It allows children to sit rear-facing from birth up to 125 cm (approximately 7 years old). This extended range makes it a favorite for parents who want to maximize safety duration.
This seat uses ISOFIX connectors specifically designed to handle the forces of a larger child. Because it removes the option to turn forward, the structure is reinforced to absorb massive amounts of energy. The rebound bar acts as a brace against the vehicle seat, preventing the car seat from flipping upward into the backrest during a collision.
- Check the weight limit — The i-Prodigi supports children up to 22.5 kg, which is higher than many standard ISOFIX seats.
- Adjust the legroom — An adjustable rebound bar lets older children sit comfortably without feeling cramped.
Joie i-Spin Safe
The i-Spin Safe is a variation of the popular i-Spin 360. While the standard 360 allows forward-facing, the “Safe” version physically blocks the seat from turning forward. This design change allowed it to pass the Swedish Plus Test.
This seat rotates 90 degrees to the door to help you load the child, but it will not rotate 180 degrees to face the front. It is an excellent option for parents who want the convenience of a spinning seat without sacrificing the safety benefits of a Plus Test badge. It is suitable from birth to roughly 4 years old (105 cm).
- Verify the install — It uses ISOFIX and a load leg, making installation simple and rigid.
- Use the inserts — The seat comes with infant inserts that must be removed in stages as the baby grows.
Why Most Joie Seats Do Not Pass The Plus Test
You might wonder why popular models like the Joie Every Stage or the standard i-Spin 360 lack this certification. The reason is simple: functionality. The Swedish Plus Test fails any seat that exerts too much force on the neck. Forward-facing positions almost always exceed these force limits.
Seats like the Every Stage are “multistage” seats. They allow rear-facing for a time, but then convert to forward-facing high-back boosters. The moment a seat offers a forward-facing mode with an internal harness, it becomes ineligible for the Plus Test seal in almost all cases. The testing facility assumes that if a parent can turn the seat forward, they might, and therefore the seat cannot guarantee low neck loads in all approved configurations.
This does not mean the Every Stage or i-Spin 360 are “unsafe.” They meet the legal R129 or R44 standards. They simply do not meet the ultra-strict neck force requirements set by VTI for the Plus Test specifically.
Comparing Plus Test Vs. Standard R129 Regulations
It helps to see the numbers side-by-side to understand why the Plus Test is so hard to pass. The R129 (i-Size) regulation is the current mandatory standard for Europe, while the Plus Test is an optional add-on.
| Feature | Standard R129 (i-Size) | Swedish Plus Test |
|---|---|---|
| Crash Speed | 50 km/h | 56 km/h |
| Braking Distance | Longer (softer stop) | Shorter (harder stop) |
| Neck Force Limit | Not strictly capped for all sizes | Max 1220 N (3-year-old) |
| Forward Facing | Allowed | Typically prohibited |
The shorter braking distance in the Plus Test subjects the seat to higher G-forces. A seat must be extremely rigid to survive this short stop without cracking or bending excessively. Joie had to reinforce the frames of the i-Prodigi and i-Spin Safe specifically to handle this violent deceleration.
Is A Non-Plus Tested Joie Seat Safe?
Yes, non-Plus Tested Joie seats are safe and legal, provided they are used correctly. Millions of children travel safely in standard R129 seats every day. The Plus Test represents a “gold standard” specifically for neck protection, but a seat without it still passes rigorous government crash testing.
Independent bodies like ADAC (German Automobile Club) also test Joie seats. ADAC scores consider frontal impact, side impact, and usability. Many Joie seats that are not Plus Tested still receive “Good” ratings from ADAC. For example, the standard i-Spin 360 has performed well in ADAC testing because it offers good side impact protection and stable installation, even if it allows forward-facing.
However, if your priority is keeping your child’s neck loads to the absolute minimum physics will allow, a Plus Tested seat is the superior choice. Rear-facing protects the head, neck, and spine by spreading crash forces across the entire back of the seat shell.
Installation Factors For Plus Tested Seats
Owning a Plus Tested seat like the Joie i-Prodigi requires you to pay close attention to installation. These seats often take up more room than compact forward-facing models. Because they must manage high energy, the connection to the car is substantial.
Space Requirements
The i-Prodigi is a large seat. In smaller vehicles, the front passenger might need to slide their seat forward significantly. This is common for any seat that accommodates a 7-year-old rear-facing. You should test the fit in your specific car before purchasing.
Tether Straps
Some extended rear-facing seats use lower tether straps that attach to the floor of the car or the rails of the front seat. The Joie i-Prodigi does not use lower tethers; it relies on rigid ISOFIX and a rebound bar. This makes it easier to install than many other Swedish-style seats that require manual strap tightening.
- Extend the load leg — Make sure the leg makes firm contact with the floor.
- Check the indicators — Green color patches on the ISOFIX arms confirm the seat is locked.
The Importance Of Extended Rear Facing
The entire philosophy behind the Swedish Plus Test is extended rear-facing. In Sweden, it is common for children to sit backward until age 4 or 5. Joie has embraced this with the i-Prodigi, pushing that limit even further to age 7.
An infant’s head is disproportionately heavy compared to their body. In a forward-facing crash, the harness holds the shoulders back while the head flies forward. This snaps the neck. When rear-facing, the head presses into the headrest, and the seat shell cradles the body. The crash forces are absorbed by the seat, not the child’s bones.
Choosing a seat like the i-Prodigi is a commitment to this safety philosophy. It eliminates the temptation to turn the child around “so they can see better” or “because their legs look bent.” Bent legs are not a safety hazard; a broken neck is.
Common Misconceptions About Plus Testing
Parents often get confused about what the badge means. It does not certify the seat for side impact (though R129 does). It specifically certifies the seat’s ability to protect the neck in a severe head-on crash.
Another myth is that Plus Tested seats are uncomfortable. This is false. Models like the Joie i-Prodigi offer deep recline positions and plenty of padding. Children are generally happy rear-facing because their legs are supported by the seat back rather than dangling in the air, which can cause numbness in forward-facing seats.
Lastly, price is not always an indicator. Some very expensive seats fail the Plus Test because they prioritize rotation or slim designs over raw strength. The Joie i-Spin Safe is competitively priced compared to other premium Swedish seats, offering a high-value entry point into this elite safety category.

Frequently Asked Questions
Can I turn the Joie i-Spin Safe forward?
No, you cannot. The mechanism is physically blocked to prevent the seat from turning forward. This lockout is a requirement for the seat to maintain its Swedish Plus Test status. It can only rotate 90 degrees to the sides for loading and unloading.
Is the Joie Every Stage Plus Tested?
No, the Joie Every Stage is not Swedish Plus Tested. Because it is a multi-stage seat that converts to a forward-facing booster, it does not meet the strict rear-facing-only criteria required to pass the VTI neck force assessments.
Does the Plus Test cover side impact?
The Plus Test focuses mainly on frontal impact and neck forces. However, since the Joie i-Prodigi and i-Spin Safe are also R129 (i-Size) certified, they have passed mandatory side-impact testing as part of that separate European approval process.
How do I know if my Joie seat is Plus Tested?
Look for the distinct gold and blue “Plus Test” sticker on the shell of the car seat. If the sticker is missing, the model is likely not certified. You can also check the official VTI website, which maintains a list of all approved car seats.
Is ISOFIX required for all Plus Tested seats?
Not always. Many Swedish Plus Tested seats use seatbelts and tethers to attach to the car. However, the Joie i-Prodigi and i-Spin Safe specifically use ISOFIX. This makes them easier to install but imposes a weight limit of 33 kg (child + seat combined) on the anchorage points.
Wrapping It Up – Are Joie Car Seats Swedish Plus Tested?
If you are asking “Are Joie car seats Swedish Plus Tested?”, the answer is a definitive yes, but only for the right models. The Joie i-Prodigi and Joie i-Spin Safe stand out as the brand’s champions of neck safety. These seats have survived the toughest crash trials in the world to earn their gold seal.
For parents prioritizing maximum safety, these models are an excellent investment. They force you to keep your child rear-facing, which is statistically the safest way to travel. While other Joie seats offer great features and pass legal standards, the Plus Test badge on the i-Prodigi and i-Spin Safe offers that extra layer of reassurance that the seat can handle extreme forces without transferring them to your child’s fragile neck.
