Before you buy

What you get, and which pieces go together.

Which base takes which seat?

Willow, Willow S, Willow SC and Cypress infant seats all fit the Aspen and Alpine bases, and those two bases take only these seats. Britax help article
The Arbor infant seat does not fit Britax ClickTight bases. It comes with its own StayTight base and can also be installed without a base. Britax help article

Reusing older parts
