Who the Willow S Infant Car Seat with Alpine Base fits

- Rear-facing infant4 to 30 lb · 17 to 32 in
- The child faces the back of the car, which keeps the head, neck and spine supported in a frontal crash. Keep this mode as long as the child fits it.

How the Willow S Infant Car Seat with Alpine Base installs
- Belt lock-off
- ClickTight installation (Alpine base). A lock-off clamps the vehicle belt so you do not have to switch the belt's retractor into its locked mode.
- Lower anchors
- Quick-push LATCH connectors. Check your vehicle manual for which seating positions have anchors, and switch to the seat belt once the child passes the anchor weight limit in the manual.
Every install is a fit between one seat and one vehicle. Read both manuals, and use a free inspection station if anything is unclear.
Will it fit your car?
At 16.9 in at its widest, this seat is one of the narrower ones in its class and is a candidate for three across in many mid-size cars.
- Check your vehicle manual for lower anchor positions and any head-restraint rules.
- Rear-facing seats need front-seat room: try the install behind the driver before you commit.
- Certified for aircraft use, so it can travel as a seat rather than checked baggage.

Is the Willow S Infant Car Seat with Alpine Base recalled?
No campaign in the current NHTSA child-restraint data names this model family, and I have not run a separate review for it. Check your seat’s model number and date of manufacture before use.
Before you buy
- Weigh and measure your child. The limits above are the manufacturer’s, and a child has to meet all of them for the mode they will use.
- Confirm the exact version. Colors, retail exclusives and model numbers change limits more often than you would expect; Britax lists 5 colors of this seat.
- Read the manual before you buy, not after. It is linked above and holds the fit rules, the install methods and the expiry.
- Check recalls by model number and date of manufacture, and register the seat with Britax so you hear about the next one.
