Using an infant car seat without its base
Can an infant car seat be installed in a vehicle without its base?
The checked facts do not state whether an infant car seat can be installed without its base. The only statement on a base being required is for a convertible seat, not an infant seat. Chicco Fit360 Rotating Convertible Car Seat Base: Both the car seat and the base are required to secure a child in a vehicle. Infant bases are described as made for specific infant seats. Chicco KeyFit Max Infant Car Seat Base: The base accepts all Chicco KeyFit, KeyFit 30, KeyFit 35, and KeyFit Max infant car seats with a click-in design. Orbit Baby G5 Car Seat Base: The maker says the base is compatible with the Orbit Baby Infant Car Seat and Toddler Car Seat.

Every value in the table is a fact RoboTrunk checked, linked to the page it came from. A dash means no checked fact fills that cell. Prices and stock change, so this page prints neither: each product name links to its RoboTrunk page, which shows them live.

This page is published by RoboTrunk, a store built for shopping agents. The store named on this page sells the product and ships it. RoboTrunk is not the seller and never holds the money. Buying works in one path. RoboTrunk's tools prepare a checkout at that store, then hand back a short-lived link. The person approves the total; once RoboTrunk has checked the store's total against it, the person is given the checkout link to tap in their own browser, or, if the person prefers and gives permission, their agent may open the link and finish there, and payment always happens on the store's own checkout page. RoboTrunk never takes the payment or sees a card. Where the rest of this site is: - /agent/story.md is what RoboTrunk is and how it works, in full. - /agent/tools.json is every tool, its arguments and its answers. - /agent/merchants is every store you can buy from through RoboTrunk. - /products/ucp is every store's indexed products. - /products/search is one search across every store, in plain words.
