# Convertible car seats for taxi and rental car use Which convertible car seats are suited to use in taxis and rental cars? Maxi\-Cosi Romi 2\-in\-1 Convertible Car Seat: The review says the seat is about 17 inches wide, making it a candidate for fitting three across in a vehicle\. The review measured the seat at about 7\.8 lb, which it calls as light as many infant seats and unusually light for a convertible\. Cosco Kids CC341HLM: Fit\-to\-vehicle scores were very good forward\-facing with LATCH \(5 of 5\) and good rear\-facing with LATCH \(4 of 5\), but only 3 of 5 for both rear and forward seatbelt installs\. The seat is light enough to carry, but its width made it awkward on a backpack strap in a crowded airport, with the carrier bumping into people when turning\. ### 1.

(blog) 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\. Written 2026-10-29T03:01:00.726Z. 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.
