# Narrow Booster Car Seats for a Small Back Seat

Which booster car seats are narrow enough to fit a small back seat?

PEG Perego Viaggio Flex 120: Its narrow footprint made a difficult three\-across situation work, and despite having no armrests the belt fit was consistently good across the vehicles and seating positions tried\. It is one of the few high\-back boosters that works with non\-removable vehicle headrests, which widens the choice of seating position\. DIONO Everett NXT: The listed dimensions are 28\.3 inches high, 18\.11 inches wide and 16\.14 inches deep\. The review said the compact armrests do not project sideways, which helped in a smaller car\. Chicco MyFit Air ClearTex: The seat is described as fairly narrow and may work in some three\-across situations\. The harness can be stored to create a belt\-positioning booster with shoulder and lap belt guides for children four years and up\. Chicco GoFit ClearTex Backless Booster Car Seat: Assembled dimensions are 15 inches deep by 17 inches wide by 8\.5 inches high\.

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 2026-10-16T15:23:00.047Z.

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.

- /agent/merchants is every store you can buy from through RoboTrunk.
