Learning Curve’s The First Years/Lamaze True Fit C630 convertible seat has been on the market since the beginning of 2008 and they’ve just introduced the Premier line.  The new Premier C670 models have an anti-rebound bar for rear-facing use, which rotates forward from under the car seat and rests against the vehicle seat back.  This anti-rebound bar, which Learning Curve calls a “rear-facing rebound management bar,” keeps the car seat from rebounding or hitting the vehicle seat back after a crash.  It also translates into more energy absorption during the crash.  The Premier models also have a ball angle indicator just above the harness adjuster strap and a 2 position recline handle.

This is a convertible (rear-facing and forward-facing) child restraint for kids 5-65 lbs. who are less than 50″ tall.  Rear-facing the seat is rated from 5-35 lbs.  Forward-facing, it can be used for children over 1 year old who weigh between 23-65 lbs.

The True Fit Premier comes with an infant body support cushion, buckle cover, a head bolster, harness strap covers, and a cupholder.
