Chicco Fit4 4-in-1 vs Evenflo Revolve360 Extend

Both are all-in-one car seats — here are their published manufacturer specs side by side.

This compares published manufacturer specs — not safety or fit advice. The seat's manual, your vehicle's manual, NHTSA's tools and a certified CPST are the fit-and-safety authority; always check them before installing.

How they differ

• the Chicco Fit4 4-in-1 is FAA-approved for aircraft; the Evenflo Revolve360 Extend isn't (harnessed seats can be FAA-approved; boosters never are — a plane has no shoulder belt)

Published limits

Chicco Fit4 4-in-1: Booster-mode weight 40–100 lb; the manual caps overall height at 57″. No backless mode (4-in-1 harness→highback booster).

Evenflo Revolve360 Extend: Rotational all-in-one (rear-facing → forward-facing harness → high-back booster; no backless mode found in manual). Forward-facing also requires at least 2 years old; high-back booster requires at least 4 years old (printed manual requirements, not just weight/height). Useful life is set by the expiration date on the manufacture label (no printed number of years).

Recall record

Chicco — 2 on NHTSA's record · Evenflo — 43 on NHTSA's record.

That is the record of the brand — not a verdict on these models. A recall names specific models and manufacture-date ranges, and a seat missing from the record is not "recall-free": check nhtsa.gov/recalls with the model and date of manufacture on your seat's label.
