Convertible car seats that leave room for a second seat beside them

Which convertible car seats are narrow enough to fit another car seat beside them in a row?

Britax Poplar S ClickTight: Its 17-inch width makes it a good candidate for three-across use, and ClickTight helps get a snug install in a tight row. Britax Poplar ClickTight: The narrow shell makes three-across possible with other narrow seats, but it did not fit a very small Sienna middle seat, and a centre position in an Odyssey left part of the base overhanging, which the review says should be checked with Britax. UPPAbaby Rove Convertible Car Seat: The seat is 18.8 in wide and is presented as friendly for small cars and three-across rows, though buyers are told to confirm in their own vehicle.

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.
