Narrow convertible car seats for three across in a back seat
Which convertible car seats are narrow enough to fit three across in a back seat?
Britax Poplar ClickTight Convertible Car Seat: Seat is 17 inches wide without cupholders and 20 inches with them. Good for small backseats; on the most upright rear-facing recline it is one of the most compact rear-facing convertibles on the market. Front-to-back footprint depends on recline setting. Britax Poplar S ClickTight Convertible Car Seat: The Poplar and Poplar S are described as among the skinniest car seats on the market, at 17 inches wide externally. The article notes it is a 2-in-1 convertible, not an all-in-one, so there is no booster mode and another seat will eventually be needed.

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. 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.
