  • Installation using the included Isofix Base with anti rotation leg and always in the safer Rearward Facing position in the car.

The new iMATRIX from Jané is the new i-Size version of the popular Matrix system. It is designed to protect your baby in the car and is suitable for use by children with a height of between 40 and 83 cm which is from birth to 18 months approx.

As the iMatrix is an i-Size car seat it means, like all i-size car seats, that it uses the ISOFIX system and not seat belts to install it into your car.

Complete with the Isofix base, there is only one simple and quick way to install it in your car - in the rearward facing position on its Isofix base. This is the safest installation system, as it prevents any installation errors that could affect safety.



Jané iMatrix iSize

The i-Size infant car seat that turns into a carrycot

The iMatrix is fitted with the “Pro-Fix” system, which means that with just one movement, it can be fitted onto your Jané chassis to make a travel system.
When used on the pram chassis or separately as a carrycot it can be fully reclined to be used in the healthier 180° Lie-Flat position which is recommended by health officials. It can also be used for overnight sleeping when used with a mattress.
When in the car the Pro-fix locking allows for ultra-quick installation in the car in the sitting-up position.

iMatrix iSize as a lie-flat carrycot

- Health Benefits -

Newborn babies should ideally lie completely flat, as recommended by health officials. This position unlike conventional infant car seats doesn’t have any time restrictions a newborn can travel in it. It also facilitates newborn respiration, nurtures the abdomen and aids optimal spinal development. The Jané iMatrix iSize innovative design recognises these important requirements and allows baby to travel in the lie-flat position on the pram chassis or as a carrycot.  In the car, the iMATRIX has been designed to be installed together with the Isofix iPLATFORM base and always in the rear facing, sitting-up position.

iMatrix iSize or Matrix Light 2!
Whats the difference?

The Difference between iMatrix iSize and Matrix Light 2

iMatrix i-Size / Matrix Light 2 main differences
As the iMatrix is an i-Size car seat it means, like all i-size car seats, that it uses the ISOFIX system and not seat belts to install into your car. Also the lie-flat functionality is limited to the pram and carrycot modes, and not available in the car. If you wish to have the option of seat belt installation and the lie-flat position when in the car, then you would need to look at the MATRIX LIGHT 2 version travel systems.



Travel System Compatible

Can be attached to all Jané pushchairs using its Pro-fix  installation system.
current models include: Kawai, Kendo, Minnum, Muum, Epic, Crosswalk R, Crosswalk Convert, Rider, Trider



i-Size Car Seats and Vehicle Compatibility

The i-Size (R129) safety standard has been developed together with car manufacturers to ensure full compatibility between the Child Restraint Systems (CRS) and the car. An i-Size Child car seat (CRS) is 100% compatible with an i-Size vehicle seat and almost all cars with Isofix anchors. You can confirm what your car has by refering to your vehicles instruction manual.
