Infant car seats that can be installed without their base
Which infant car seats can be installed in a vehicle without their base?
Peg Perego Primo Viaggio Urban Mobility: It is a baseless infant car seat that can be installed without a base using built-in LATCH connectors or the Euro belt path method. In crash testing the seat did not keep its structural integrity in any of the four rear-facing runs; there was significant cracking around the seatpan and along the internal seams of the seatback, and in one run with a weighted 12-month dummy on lower anchors parts of the shell came away and the crotch buckle area pulled through, which the testers say raises concern for injury risk in a later crash. Britax Willow S: There is an extra belt path on the back of the seat for base-free installation. Bugaboo Turtle Air Shield by Nuna: Shows the carrier being installed without the base using the vehicle belt (European-style belt routing), which the video presents as the way to use it in a taxi, rideshare or on holiday. Britax B-Safe Gen2: Britax publishes a B-Safe Gen2 user guide plus installation videos for lower anchors, vehicle seat belt, and installing without the base.

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.

About the recall notices above: each matches a model named in a regulator's notice, as the index stood on 2026-09-25. This listing is the brand and model a regulator's notice names. Two AI models judged it so independently. It does not mean the unit on sale is from an affected batch, that the store knew, or that the product is illegal where the store sells it; a US recall does not bind an Australian store. The notice may cover only some serial numbers or dates of manufacture, which a listing does not show. RoboTrunk never limits or blocks a purchase over a notice; read the notice and decide.
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.
