Forward-facing weight and height limits on convertible car seats
Which convertible car seats allow a larger child to stay forward-facing for the longest?
Britax One4Life ClickTight All-in-One: Harness mode is only for children weighing 5-65 lb and 49 in or less tall. Maxi Cosi Pria™ All-in-One Convertible Car Seat: The maker's page says rear-facing is 5-40 lb and 19-40 in, forward-facing 30-65 lb and 34.4-49 in, and belt-positioning booster 40-100 lb and 43.4-52 in; the store's listing gives different limits (rear-facing 4-40 lb, forward-facing 22-65 lb and 29-49 in, booster 43-52 in), so the sources disagree. Evenflo Revolve360 Extend: Three modes: rear-facing 4 to 50 lb, forward-facing 30 to 65 lb and booster 40 to 120 lb. Britax One4Life All-in-One Car Seat: One seat covers three stages and is sold as growing with the child for 10 years: rear-facing infant and toddler use 5-50 lb, forward-facing harness use 30-65 lb, and high-back booster use 40-120 lb. Britax One4Life Slim: It converts from rear-facing infant/toddler use at 5–50 lb to forward-facing at 30–65 lb and high-back booster at 40–120 lb.

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.
