Isofix Base for the Be-Cool Zero & Jane Koos Infant Car Seats (Originally known as "Koos Platform")

The Koos / Zero Platform is an accessory that has been specially designed to make it easier to install the Jané Koos infant car seat in the car. It installs using the Isofix points in your car for optimum safety and speedy attachment, and has passed the strict safety tests of European Standard ECE R44/04 semi-universal category.

Its new and unique fastening system, using the PROFIX system (patented) lets you install and remove the Jané Koos infant car seat with just one movement and in a few seconds. Being quick and easy means less time in the rain when taking baby in and out of the car on those cold windy rainy days.

Its anti-rotation system with stabilizer; height adjustable support leg ensures the base is sturdy and level when installed.

Also on the Koos Platform is a special barcode, known as a QR (Quick Response) code. When scanned with a smart phone, these codes will reveal extra information about the seat, including a video fitting guide. 

Please Note:

From summer 2018 the Jané Koos Platform will be known as the Zero Platform. There are no Changes, just the name.

Please also note that the new iSize version of the Koos car seat is not compatible with this Koos or Zero platform, they are compatible with the Jané iPlatform iSize base only.

Crash Test Centre



Jane Crash Test Research Centre

The Jané Crash Test Research Centre was built in 2003 when, as a result of our commitment to child safety, we decided to create our own crash test tunnel where we could test our seats to the limit to achieve a level of safety that goes beyond the legal requirements.

All the Jané seats are created in the JANÉ CRASH TEST RESEARCH CENTER, the only private crash tunnel in Spain for researching child safety.

As it is at our factory in Palau-Solità i Plegamans (Barcelona), we can use the Crash Test as much as is necessary (and then some more). And that's how we can offer you the most tested seats on the market with the strictest certification of Europe.

Crash Test

Our car seats can be tested up to 250 times before being put on the market.

We stage crashes equivalent to 85 km/h (53 mph) in the car - much higher than the European Safety Regulations of 30 mph or ADAC crash tests at 40 mph.

Great solid product that arrived day after ordering. I do feel the instruction leaflet would be improved with adding some text and not just relying on pictures as you cannot be completely sure you have got things fully installed properly. Also would like to see the ability to order and pay over the phone rather just over the net.

This should be a must have if you have the matching car seat! It makes it fit rock solid, which is more reassuring than without it. Thank you very much Jané - I will be back as a very happy customer!
