Britax Willow S ClickTight Infant Capsule with Alpine Base

The Britax Willow™ S ClickTight® Infant Capsule with Alpine Base is a lightweight, rear-facing infant car seat for your newborn's first year and beyond. It's suitable from 1.8kg up to 13.6kg and 81cm tall, with an infant insert pillow for a snug fit for babies under 5kg.

The Alpine base brings Britax's ClickTight® Installation to an infant capsule for the first time. Open the base, thread and buckle the seatbelt, then click it closed, and the ClickTight indicator shows you when it's secure. The base also includes a ReboundReduce® stability bar to help minimise movement in a crash, and level indicators with spring-assist recline to get the angle right.

At just 4.1kg, the capsule is easy to carry from the car to the house, and it clicks onto a wide range of strollers, including UPPAbaby, Bugaboo and Nuna, to make a travel system. It can also be installed without the base using the vehicle seatbelt, with an extra belt path for added stability, which is handy for taxis, travel and grandparents' cars. SafeCell® technology helps manage crash energy, and the SafeWash® cover is safe to machine wash and dry, naturally flame-retardant with no added FR chemicals.

Stroller Compatibility (Travel System)

The Willow S clicks onto a wide range of strollers to make a travel system. These strollers are certified compatible in New Zealand, tested to AS 2088:2022 with the stroller brand's original adaptors:

Source: Britax NZ Willow S Compatibility Chart, v1.3 (January 2024). Only the strollers listed have been certified compatible. Stroller manufacturers change their products from time to time, so we recommend checking the fit in our East Tāmaki showroom or with your retailer, and always refer to the instruction manual.

Infant Capsule or Convertible Car Seat from Birth?

An infant capsule like the Willow S lifts out of the car, so you can carry your baby without waking them. A convertible seat stays in the car but lasts for years. Many families start with a capsule, then move to a convertible like the Poplar S or One4Life Slim when their baby outgrows it.
