Car seats with a top tether
Which car seats in the checked listings mention a top tether for forward-facing use?
Britax Allegiance: The seat is praised for clear labels, including one by the crotch buckle slot spelling out which slot may be used rear-facing, forward-facing under 30 lbs and forward-facing over 30 lbs, plus labels for lower-anchor storage and top-tether routing. Nuna REVV maxx: The shop demonstrator shows five recline positions in each direction, adjustable while the seat is installed, but the top tether may need loosening or retightening after a recline change.

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.
