Car seats that convert from harness to booster
Which car seats can switch from a harness to a booster as a child grows?
Britax Grow With You ClickTight Harness-2-Booster Car Seat: Harness mode is for 11.3–29.5 kg (25–65 lb); booster mode is for 18.1–54.4 kg (40–120 lb). Nuna ROYL: In forward-facing harness mode with the vehicle belt and tether the seat is for children 2 years and up, from 30 to 65 lbs. It notes many boosters stop around 100 lbs, and treats the 120 lb booster limit here as a real advantage for longevity.

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.
