Booster seats with reported fit in specific car models

Which booster seats are reported to fit a specific car model, such as a Honda Civic or a Tesla?

Diono Radian 3RXT: The video reports successful three-across use in a Tesla Model Y and enough narrowness for two seats plus a tightly fitting passenger. Britax Skyline 2-Stage Belt-Positioning Booster Car Seat: A forum user reported that the Skyline struck the fixed rear head restraint in a Civic Sport Hatch, leaving a gap behind the booster; Britax reportedly advised that this installation was unacceptable.

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.
