The Chicco Corso Flex with Second Seat is designed for parents who need a reliable convertible stroller without breaking the bank. In our hands-on tests, it shone in critical safety areas:
Using child-sized crash dummies, the stroller's robust frame prevented harmful head injury forces in both front- and rear-impact simulations. The seats and structure also avoided secondary head impacts, earning top marks for safety.
Folding takes under 30 seconds with a one-handed mechanism, and it stands upright when folded—perfect for trunk storage. Lifting it (28.4 lbs) into a car is manageable for most adults. Attaching the second seat is intuitive, though pushing over gravel or curbs feels slightly bumpy due to standard suspension.
It glides smoothly on sidewalks and handles tight corners with a tight turning radius of 4.5 feet. All-wheel design aids stability, but it's not as agile as lighter premium models on uneven terrain.
Three recline positions per seat ensure naptime comfort, and the large canopy provides UPF 50+ coverage. The 10-lb storage basket holds diaper bags, and dual cupholders are a parent win. Unfolded, it measures 43.5 x 24.4 x 41.3 inches—compact for a double.
