Query: PLEASE DO NOT USE THIS!!!!!

I am a certified Child Passenger Safety Instructor for over 10 years. These are NOT safety tested and can void all warranties for the automobile and carseat. You auto insurance may also claim that you used an unapproved product. The government has strict standards for carseats to pass crash tests FMVSS 213. If the product does not have that stated on the product then it can be more of a danger. If you can not install a carseat with less than 1" of movement, you may need to move it to another seating position, get another seat or contact a Certified Child Safety technician in your area. (NHTSA, Highway Patrol, Police, Fire Dept, Health Dept,) Keep them seated and buckled.
