Maxi-Cosi Romi 2-in-1 Convertible Car Seat | live price, prepared checkout

Built for shopping agents: what RoboTrunk does for every product

We asked shopping agents, including Meta's Muse first-hand, what they need from a store. This is what they asked for, and what we have built.

RoboTrunk is working through its catalogue, so a step may not be done for this one yet. Where a step is done per product, the line ends with what is done for this product.

• Deep research: We read the maker's manual, independent reviews, video review transcripts and the store's own page, and publish each finding with its source and the date read. check_product returns them with a source for each. This product: 31 checked facts, research depth trimmed read, checked 2026-10-19T15:59:39.516Z, in the evidence pack.
• Receipts: Every published fact has a receipt showing its source quote. check_product and get_product return the checked facts that have one. This product: each checked fact listed below has one; the source quotes are in the evidence pack.
• Safety: check_product asks the product-safety regulators live (US CPSC, NHTSA and FDA, Health Canada, the UK's OPSS, Australia's ACCC) whether a recall names a product, listed here or not, and flags a match with its notice; a recall never blocks the buyer. This product: this page holds no recall result for it yet; check_product asks the regulators now.
• Recall watch: watch_recalls tells the buyer if a product bought here is recalled later.
• Second-hand listings: check_listing runs the same recall check on a second-hand listing someone found, and adds what the listing leaves out and the price new.
• The real price: The full price to the buyer's country, with shipping and tax, each part quoted from the store's policy or, where a part is not settled, what the total depends on: check_product and search_catalog take the buyer's country and postcode. This product: this store's price was read from its catalogue at 2026-10-22T19:35:42.506Z.
• A checkout that finishes: RoboTrunk lists only stores whose agent checkout it has verified. create_checkout prepares the order at the store; complete_checkout returns a link to the store's own checkout. The checkout can be finished in either of two ways: the person taps the link in their own browser, or their agent opens it and completes the checkout. RoboTrunk checks the store's total against a budget ceiling before it issues the link. Payment always happens on the store's own page, and RoboTrunk never holds the money. No store pays for placement; RoboTrunk may earn a commission from some stores via their affiliate programs.
• Markdown copy: Every page has a Markdown copy: this page's copy.
• Photos and ratings: Search results carry the product photo and, where the store's own page publishes one, its rating (search_catalog).
• Fit answers: check_fit answers whether a listing fits a car, pram or bottle, with the exact quote from the store's page, or says it is not known.
• Back-in-stock watches: watch_back_in_stock starts a watch on a listing the store shows as sold out; get_back_in_stock_watch shows when it is back in stock.
• Maker's manual: ask_product_manual answers from the maker's manual with the exact passage and page, or says the manual does not cover it.
• Tools and guide: Every tool and its description is at https://robotrunk.com/mcp; the guide is at /agents.md.
• Research from other stores: Coming soon: reading other stores' listings of the same product as new research sources.

Checked facts

Each fact below was checked against the source it cites before it was published. Each carries that source's link and the time RoboTrunk read it. 31 checked facts, checked 2026-10-19T15:59:39.516Z. Research depth: trimmed read. Deep read: the store's own data and 13 outside pages (the store's own product page; manual; review; blog; regulator recall search (CPSC (United States)); regulator recall search (Health Canada); official safety test results (CREP, the Child Restraint Evaluation Program); official safety test results (NHTSA's Car Seat Ease of Use Ratings); official safety test results (ADAC's child seat test); video review (derived summary of its captions)), each read in full by RoboTrunk and trimmed to its main content, then written up and checked. Facts from the maker or a manual quote the page word for word; what real users report is summarised with a link to the page read. Recall status was checked directly with CPSC (United States), Health Canada: The CPSC recall search for Maxi-Cosi and this Romi model returned no records. Health Canada's open recall data has a single Maxi-Cosi record, but it is the Mico infant car seat and base from 2010, a different product, so no recall applies to this seat. Official safety test results were looked up directly with CREP, the Child Restraint Evaluation Program, NHTSA's Car Seat Ease of Use Ratings, ADAC's child seat test: CREP, the Child Restraint Evaluation Program (Australia and New Zealand): CREP's published list of 216 rated seats includes many Maxi-Cosi models (Mico, Moda, Nero, Nova LX, Pria LX, Euro NXT and others) but no Romi 2-in-1, and the list is complete, so this seat has not been rated by CREP. NHTSA's Car Seat Ease of Use Ratings (United States): NHTSA rated a Maxi-Cosi Romi convertible, model CC228-FNA made 2022-05-17 with 5–40 lb and 19–43 in limits and hook-style LATCH, at 3 of 5 stars overall in both modes; that is a different Romi variant from this listing's SKU CC402HHH with 30–50 lb forward-facing limits, so the scores are not carried over. ADAC's child seat test (Germany, the UK and Europe): ADAC's published list of 527 tested seats since 2015 includes many Maxi-Cosi models but no Romi, and the list is complete, so this seat has not been graded by ADAC. Not read, because they are member-only or refused RoboTrunk: Consumer Reports car seat ratings, Which? child car seat tests, JPMA certified products.

The full evidence pack, with every citation, source and gap.

Questions we researched but could not confirm

Every fact above is cited. To find them we read the store listing, the manual, owner reviews, blogs, video reviews, the recall records of CPSC (United States) and Health Canada and the safety test results of CREP, the Child Restraint Evaluation Program, NHTSA's Car Seat Ease of Use Ratings and ADAC's child seat test and searched for the maker's page, regulator recall notices and owner forums. We also chased the questions below across those sources and found no reliable answer, so you know exactly where the evidence ends and never have to guess.

• How many years is the seat good for before it expires?
• What does the Maxi-Cosi warranty cover and for how long?
• Is the cover removable for washing without unthreading the harness?
• What is the seat's real width: 17, 18.5 or 21.25 inches?
• How exactly do you use the top tether as a carry strap?
• Will the harness fit a chunky toddler close to the weight limit?
• Does it fit three across in a typical vehicle?
• Is there energy-absorbing foam in the shell, and where?
• Are the lower anchors hook-style or push-on on this version?
• Which travel bags or strollers is it designed to work with?

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.
