In the latest edition of Which? Magazine, they have given the peg perego viaggio twist car seat a 0% safety rating after it failed its safety tests, and advise parents to stop using it immediately.
“During the test, when the seat was set up in a rear-facing configuration, the support leg on the car seat base crumpled, and the momentum of the crash hurled the car seat forward. This caused the car seat to come loose from the Isofix base and fly through the test vehicle.
When the seat was set up in a forward-facing configuration, the support leg broke again and, while the seat remained attached to the base, it still flew up into the air. This would mean the seat (and your child's head) could hit the ceiling of the car with force.”
