How the Willow Infant Car Seat with Aspen Base installs

Belt lock-off
ClickTight installation. 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?

Britax does not publish a width for this seat, so measure your back seat and compare it with the seat in a store before buying. It weighs 8.99 lb, which matters if you will move it between cars or carry it through an airport.

  • 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.

Before you buy

  1. 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.
  2. Confirm the exact version. Colors, retail exclusives and model numbers change limits more often than you would expect; Britax lists 3 colors of this seat.
  3. Read the manual before you buy, not after. It is linked above and holds the fit rules, the install methods and the expiry.
  4. Check recalls by model number and date of manufacture, and register the seat with Britax so you hear about the next one.
