Our patented Safe Stop® harness component is a load-limiting device that absorbs energy in a crash. The unique design offers an additional layer of protection by reducing impact to a smaller, forward-facing child.
Side Impact Protection
We’ve got your child’s safety covered. Rainier seats feature extra-deep, aluminum reinforced sidewalls that extend straight forward and are lined with thick, energy absorbing foam. We performed rigorous side impact testing to achieve the proper size, shape and strength that best protects children from side impact forces.
As safety experts, we think of every precaution. Rear-facing tether capability helps reduce seat rotation during an impact. This unique feature is not found on every car seat. We built it in here for an extra layer of protection when your child is rear-facing.
“My husband and I ordered this car seat for our 4-year-old son, and we love it. I knew I wanted something that went above and beyond all safety regulations, and I really feel Diono has done that. It's easy to set up and install.... Thank you, Diono, for making a great product that I can feel safe putting my kids into.”
