OUT OF STOCK- PRODUCT UNAVAILABLE Jane is one of two companies in all of Europe that has their own dedicated car seat sled test facility. That means that Jane can afford to do multiple tests to get it right and compare the safety of their car seats to competitors. The Jane Indy Plus car booster seat has side impact protection, with two separate, adjustable sections for the torso and head/neck areas. The LATCH connections, used in conjunction with the 3 point harness of the seat belt, make this the safest booster seat on the market since the shoulder and lap belt do not have to be reattached after the child is removed from the booster car seat to ensure that the seat does not become a hazard. An unattached, unoccupied car seat in a car can be a very dangerous object for passengers if the car is involved in an accident or even just brakes suddenly. For kids 30 to 80 lbs.
