Britax Willow SC Review 2026: The Good and the Bad
The Willow SC is one of Britax's newest infant seats. It comes with the Alpine base, which features an anti-rebound bar and ClickTight technology for an easy seat belt installation. The Willow SC also has a one-hand adjustable handle and the fabric is free of flame retardants.
Need Help Choosing a Car Seat?
Seat is Good for You If:
You would like a car seat with flame-retardant-free fabric.
All of the Willow SC fabric options are free of flame-retardants, so you can choose any color that you prefer!
You want a car seat that’s easy to install.
Britax has added a Clicktight mechanism to the Willow SC’s base that makes installation effortless. You really don’t have to do much except route the seat belt, buckle it in, and then close the Clicktight mechanism. The mechanism removes many inches of slack for you so you don’t even need to tighten the seat belt.
You need to fit 3 across.
Like most infant seats, the Britax Willow SC is very narrow. Thanks to its 17″ width and easy installation, this could be a good option in a 3 across configuration.
Use Caution if:
You have a specific stroller in mind to use or if you already bought one.
At this time, there are only a few strollers that the Britax Willow SC is compatible with. You can find a chart of which strollers are compatible here.
Child Fit Information
Installation Information
Airplane Use
The Britax Willow SC is a recommended choice for both domestic and international travel as it is FAA-approved. When traveling within the United States and Canada, installing the seat without the base is a breeze, as the seat belts in these countries have locking mechanisms that ensure a secure fit. For international travel, it is recommended to pack the base in your luggage and utilize its seat belt lock-off or lower anchors for installation because, typically, seat belts in other countries will not lock. If you choose not to travel with the base, you will need to contact the manufacturer for a locking clip and learn how to use it before you travel.

SITS Bottom Line
The Britax Willow SC infant car seat offers several standout features for safety and convenience. It comes with flame-retardant-free fabric options and an easy-to-use ClickTight mechanism for effortless installation. This seat is also narrow enough to fit in a 3 across configuration, ideal for families with multiple young children. However, compatibility with strollers is limited, so consult the manufacturer’s chart if you have a specific stroller in mind. The anti-rebound is an additional safety feature that we love to see.
