# Booster car seats for small or tight back seats

Which booster car seats suit small or tight back seats?

PEG Perego Viaggio Flex 120: Its narrow footprint and lack of armrests let it fit a tricky three\-across arrangement\. Its three width modes let it stay narrow enough for three\-across installations in small cars or spread to fit larger children\. WAYB Pico: After six years and three children using the same seat — in cars, rental cars and tight three\-across setups — the writer still would buy it, naming portability, the compact fold and easy fitting in tight back seats as its biggest strengths\. The video shows the seat folded inside its bag small enough for an overhead bin, roughly the depth of a standard carry\-on and a little shorter\. Maxi\-Cosi RodiSport: A forum post describes the RodiSport as on the narrower side, though not skinny, which parents may like for smaller spaces\.

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 2026-10-11T19:47:43.729Z.

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.
