# Infant car seat bases for small cars
Which infant car seat base fits well in a small car?
Britax StayTight Base: The review reports that the car seat base fit in rear\-seat footwells of most four\-door sedans tested\. Cybex Gold Aton G Base: The same blog owner found the Aton G plus base left very tight clearance to the front seat in a Mini Clubman, though it was still usable\. Cybex Cloud G Base: The writer says the maker's 5\-second install claim held up in practice and that the rigid arms remove the loose\-fit problem typical of strap\-based bases\. Doona Doona\+ Car Seat Base: The base is wider and bulkier than many competitors, which can make a tight install harder in smaller cars and on padded or contoured vehicle seats\.

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.
