Diono Rainier Convertible plus Booster Preview


Diono Rainier - ClaraThe new convertible+booster lineup from Diono features deeper side wings than the previous Radian models and some other minor changes. In the head area, a compression wall design features a rigid double wall structure for enhanced side-impact protection. The outside wall compresses under load to absorb additional energy in an impact, enhancing side-impact crash performance without increasing width. New fabrics on certain models wick moisture for comfort. The harness webbing is slightly different and the seat now comes with 2 sets of harness strap covers.

The Diono Rainier, Paifica & Olympia are either currently shipping or coming soon to Amazon.com and specialty retailers.  Stay tuned for the Diono Rainier review at CarseatBlog!

Edited to add: Here are a few comparative pics showing the Diono Rainier next to the previous generation Diono Radian R120. Even though it looks much wider, the Rainier is actually only 1″ wider but the widest point is now up at the top. The side walls of Rainier are also considerably deeper than its Radian predecessors.
