Murphy said she was among that 35 percent.
She said she considered wedging a rolled-up towel under the seat, before deciding to use a common toy, a pool noodle, instead.
“The recommendation we got was the noodle. I have to say I never felt 100 percent secure, because it moved a little bit more,” said Murphy of Hilliard.
Lead author of the study, Julie Bing, is urging parents to make sure the angles of the vehicle seat and the child car seat align.
Parents should measure the car seat and the inside of the vehicle to ensure a good fit, Bing said.
“We recommend parents go to the store and ask if they can take the model off the shelf and go out to their car and try it. It might look great on the shelf and have the greatest safety ratings, but if it doesn’t fit in your vehicle it may not be the best option for you,” Bing said.
Murphy said she agrees.
“You just assume that any car seat is going to work in any car. We certainly found out multiple car seats later, that we almost had to try the car out on the car seat and vice versa, to make sure that it was going to work,” Murphy said.
Another goal of the study is to share the data with vehicle and car seat manufacturers to help improve designs, Bing said.
