Diono Rainier Customer Reviews

There are many satisfied user of this convertible Diono Rainier car seat, you can read some of Diono Rainier review below. Hope it can helps to make the right decision about this car seat.

“Nice sturdy seats, very heavy, it is a steel frame after all. My son likes it a lot he’s three and my six year old uses it as a booster. As a booster it lacks armrests like the graco boosters have and no lights either. However, this seat is definitely safer than the graco. It only comes with one cup holder, wish it had more, but again safety over luxuries.”

“Love this seat, so does our little girl. We bought two Radians when they were owned by Sunshine kids and loved those seats. We liked the fact that we could pick from a wide range of colors, to match her personality, or mine 🙂 The only draw back, the seat runs warm. Every time we take our baby out of it she is dripping in sweat, not the best when you live in Phoenix.”
