The Willow S Infant Car Seat by Britax offers you peace of mind while riding with your precious cargo. This baby car seat is side impact tested and includes an array of features for your convenience. The ClickTight technology allows you to install the car seat securely and with confidence. The 5-point harness spotlights the RightSize system that allows adjustment points at the hips, shoulders, and between the legs, creating a perfect and cozy space for your little one.

The Willow S Infant Car Seat by Britax includes the Alpine travel car seat base equipped with a ReboundReduce Stability Bar that minimizes movement and maximizes safety and convenience. When it's time to stroll, the baby seat easily snaps to the Britax Brook, Brook+ and Grove strollers (sold separately) in both parent-facing and forward-facing modes, allowing baby to face the parents or face the world. This seat features a washer and dryer-friendly SafeWash car seat cover and inserts with naturally flame-retardant fabrics. Every part of this car seat is 100% FR free, so you can rest assured baby's precious skin is not in contact with any nasty chemicals.

  • CLICKTIGHT® INDICATOR: Helps provide a visual guide while installing the base. Indicator window may vary by model. Refer to user guide for specific instructions.
  • ROOM TO GROW: Willow S infant car seat, rear-facing only; 4 to 30 lbs
  • LIGHTWEIGHT & EASY TO CARRY: Move this car seat and base from car to stroller in a snap
  • WASHER AND DRYER-FRIENDLY: SafeWash fabrics mean no more hand washing or waiting for the car seat cover and stroller insert to air-dry. Just quick and easy cleanup, so you can keep moving
  • NATURALLY FLAME-RETARDANT FABRICS: Featuring 100% fire retardant-free, naturally fire resistant fabrics as well as foam free of any added fire retardants
  • INFANT INSERT PILLOW: This rear-facing car seat is designed to provide a more comfortable and customized fit for newborns under 11 lbs
  • REBOUNDREDUCE™ STABILITY BAR: Alpine infant car seat base helps minimize movement in a crash; carry handle provides stability when used in the upright position
  • PLUSH HARNESS PADDING: Travel car seat with an extra layer of cushioning helps prevent skin irritation and keep your child comfortable
  • EASY FIND AND RECLINE: This car seat features level indicators and spring-assist recline that make it easy to find the correct installation angle for your vehicle
  • SPACESAVER™ DESIGN: Slim outside, spacious inside; this infant car seat frees up backseat space while giving your child plenty of room for the ride

Free of added fire retardants

Britax is fully transparent about their manufacturing process and guarantee that their car seats are completely free of any added fire retardants. However, their products are manufactured in the same facilities as other gear that does contain FRs so there is a chance of potential FR carryover. We believe in full disclosure and transparency and appreciate Britax's honesty and effort to produce fire resistant products without the addition of chemical fire retardants.

Prompt arrival
It works as it should. I have a 500 amp fuse inside. It came with a 100 amp fuse already installed. I have heard too many horror stories about being a "team no fuse". I'm glad mine came the following day after ordering it. The voltmeter is nice and clear. Although I won't keep it on all the time, just to show off when I have my hood up at gatherings 😎
