CYBEX Aton G2 Base: Store lists dimensions 26 inches long, 14.5 inches wide, 27.1 inches high. Store lists the base weight as 9.9 lbs. PEG Primo Viaggio Extra Base: The base is compact enough to fit in smaller vehicles, similar to the Chicco KeyFit based on the reviewer's measurements. The base weighs 7.4 pounds and is about 22 inches long, 15 inches wide, and 12 inches deep. Clek Liing Car Seat Base: The base is 22.6 in deep and 13.2 in wide. The Liing base weighs 17 lb. Orbit Baby G5 Car Seat Base: The base length from back to knob is 20.5 inches (52 cm). The blog reports the base weighs about 29 pounds and the carrier about 15 pounds empty, making the system very heavy to lift; this conflicts with CSFTL's measured base weight of 14.4 pounds. babyark G01 Smart Base: The Smart Base weighs 18 lbs (8.2 kg). Britax BOB Gear Wilder Infant Car Seat Base with ClickTight: The review states the base weighs 4.63 kg and measures 59 x 25.73 x 21.06 cm.

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.
