Infant car seats that install without a base

Which infant car seats can be installed without a separate base?

Clek Liingo: The Liingo is a baseless infant car seat whose built-in LATCH connectors eliminate the need for a separate car seat base. Britax Willow S: The carrier has an extra rear belt path for installation without its base. Testing measured the carrier alone at 9.7 lb and reported a 4–30 lb child range and 32-inch maximum height; buyers should still follow their exact seat label and guide because Britax says ranges vary by model. Chicco KeyFit 30: For city dwellers using taxis or ride shares the video says the seat needs no base, using the seatbelt hooks on the side. The seat is designed for infants from 4 to 30 pounds and up to 30 inches tall. Cybex-dc / CYBEX Cloud G Pro: Certified for aircraft use if used without the base. Maximum child height is 32 inches. Cybex Cloud G Pro Comfort Extend Infant Car Seat: It is certified for aircraft use only without the base; owners should confirm airline acceptance. It is intended from newborn to about 18 months, for children weighing 4–30 lb and no taller than 32 inches. Cybex Aton G: Testing highlighted push-on LATCH connectors, the no-rethread harness, flame-retardant-free fabric, adjustable base, belt lockoff, and baseless use as positives or useful features. Use requires a child weighing 4–35 lb and measuring 17–32 inches, with at least one inch above the head.

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.
