Overview
A no-rethread harness and a headrest that adjusts with one hand let this Evenflo seat grow with a child through four modes, rear-facing to backless booster. SecureTight tensioning helps tighten the install with either the latch or the vehicle belt.
One seat that covers every stage while staying narrow enough for three across is the case for it. It is heavy, and the full mode range only pays off if the family uses it for years.
Who it's for
Families with tight back seats, or several kids in a row, gain the most from its narrow build. Those moving a seat between cars every day will feel its weight.
Pros and cons
- Four modes from birth to booster
- Narrow for three-across setups
- Multiple recline positions
- Two dishwasher-safe cupholders
- Heavy to move between cars
- Many modes and settings to learn
Performance notes
Fit and safety hinge on a tight install, which SecureTight assists by helping tension the belt with less effort. The no-rethread harness rises with the headrest, so straps follow the child's growth without being rethreaded.
