The Diono Solona is a popular high-back booster seat designed for children from 40-120 lbs and 38-63 inches tall, offering a convertible design that shifts to backless mode as kids grow. In our hands-on testing, it earned an overall score of 76/100, excelling in ease of use and vehicle compatibility but falling short in crash protection. Ideal for families needing a slim, lightweight option (just 10.4 lbs), it's a solid mid-range pick—but we've found better performers for safety-focused parents.

View Chicco KidFit Zip Plus for the top safety pick today.
Safety is priority one for any booster seat. The Diono Solona scored marginally in crash tests (65/100), with decent head and torso protection but weaker side-impact performance compared to class leaders. In simulated frontal crashes at 30 mph, it managed 3.2g chest acceleration—acceptable but not elite (top seats hit under 2.5g).
For better protection, consider the Chicco KidFit Zip Plus, which uses reinforced steel framing for 82/100 crash scores and superior rebound control.
Pros of Solona Crash Performance:
Cons:
Where the Solona shines is usability, scoring 85/100 overall. LATCH-free install takes under 2 minutes: buckle the lap/shoulder belt, and it's secure. Harness adjustments are intuitive, and converting to backless mode requires no tools—just fold down the backrest.
Child entry/exit is smooth (good ratings across 40-100 lb testers), with wide armrests and a 13.4-inch seat depth for comfy rides. Buckle release is easy for kids 5+.
Quick Tip: Test fit in your vehicle first—pairs best with sedans and minivans.
