There are some tougher tests which guarantee a superior crash safety for your child. The Swedish Plus test is one of those tests, and it means the car seat is being tested with a higher speed and shorter breaking distance.

The Swedish Plus Test is one of the hardest tests to pass and unlike the usual approval, the Plus Test is a voluntary test and it is up to the manufacturer if they want to Plus Test the car seats or not. Plus Tested car seats ensure that your child is not exposed to high-headed forces during a frontal collision. Plus test is a supplementary test by VTI, the National Road and Transport Research Institute, on car seats intended for the Swedish market. All car seats are approved for assembly at all locations in the car and are available in two versions, max 18 kg for ISOFIX or max 25 kg for car seats with belt attachment. Today it is not possible to Plus test forward-facing car seats, combination car seats or booster seats because it is not possible to be guaranteed that the child is not exposed to high neck forces. Sweden is the world leader when it comes to child safety by car and it is therefore not surprising that Plus Test is a Swedish approval.
