Parents are being urged not to buy a child car seat and a base after they reportedly failed crash tests, with an infant dummy sent flying through the air.

In horrifying footage, Recaro SmartClick Base can be seen staying in place during a test run, as the Recaro Optia car seat apparently comes off and flies forward. It takes with it the child dummy strapped to the seat. The chilling footage has emerged as the independent product testing magazine Which? has branded the base and seat a “Don’t Buy”.In a statement Which? said there was a “high risk” that in a real-life accident, if the car seat flew off, a youngster could suffer serious injury. A spokesman said: “During our latest child car seat crash testing, this seat experienced a failure which would result in its test score being instantly lowered to a Don’t Buy score … There is a high risk, in a real accident, that if this occurred a child could be seriously injured, as could anyone who was hit by the loose child car seat.”
