    Great safety features, even better fabrics and quality

    My older daughter has the Diono Rainier but is no longer made. So we got the Radian 3QX instead for our youngest daughter. The fabrics and overall quality is 10/10. We got the jet black colour and it's amazing materials, I wish my car has this fabric on my seat! The car seat is currently facing backwards for our little one, but I love the low profile so I know she is protected by the door (not just the window which I feel could likely break on impact if ever in a crash, as some seats seem to be made really high and raised up). The safety features I read make this seat incredibly safe. I feel very confident knowing my little girl is so well protected. This chair will last her years. It arrived VERY quickly from Snuggle Bugz, I think within 3 days it was at my door. I bought it on sale too so for the price I was very overall happy. Only reason I didn't give it 5/5 is that it is quite bulky around the head piece. I understand it's all steel reinforcement and material that will protect my daughter which IS great and more important than aesthetics, but having to maneuver her to get in rear-facing without hitting those U-shaped brackets coming from the tops needs a little technique. BUT once she is forward facing this will be easier I'm sure. Again, it adds to her safety in the seat so I really can't complain!
