Does the Joie Bay Latch SI work rear-facing?

No. It is forward-facing only, starting with the 5-point harness at 30 lb and 27 in tall. Younger children need a separate rear-facing seat first.

How long can my child use it?

Through three stages: harness to 65 lb, highback booster to 100 lb and under 57 in tall, and backless booster to 120 lb and 43–60 in tall. The seat expires 10 years after purchase.

How does the no-rethread headrest work?

The headrest moves through 15 positions with the harness attached, so you raise or lower it as the child grows without removing the seat or rethreading straps.

Is it easy to move between cars?

It weighs 23.7 lb and is 19 in wide, so it is better suited to staying installed in one vehicle. Moving it regularly is doable but awkward.

The seat, its LATCH connectors and the harness come together. A backless booster setup uses the same seat base once the back is removed.

How does it compare with a dedicated booster?

It covers harness and booster years in one purchase, but dedicated boosters are lighter and narrower. Choose this if you want one seat for the long haul.
