Methodology

How we research

Published in full so you can disagree with it. This is the method behind every specification, score and recommendation on the site.

What we do for every product

Each of the 50 products on this site went through the same five steps, and the dates of each check appear on the product itself.

The five scoring criteria

Every product carries a 0-10 score in five categories, weighted equally into an overall figure. They are published so you can disagree with the weighting rather than having to guess at it.

The five criteria and what each one measures
CriterionWhat it measuresWhy it is weighted this way
InstallHow easy a correct, tight installation is to achieve and repeat — levels, tensioners, belt path clarity, LATCH hardware, recline adjustment rangeInstallation error is the dominant real-world failure mode, so a seat that makes a correct install repeatable is doing the most valuable thing available to it
Fit rangeHow long the product is usable: published height and weight limits, shell height, harness slot range, stages coveredRear-facing time is the most protective variable a parent controls, and a longer range directly buys more of it
Vehicle fitFootprint, front-to-back depth rear-facing, width for three across, behavior on sloped benchesA seat that does not fit the car is the wrong seat regardless of any other quality
Daily useHarness adjustment, recline, cover removal and washing, carrier weight, buckle qualityInvisible in a crash test, and the reason a seat gets used correctly at 6 a.m. in February
ValueWhat the price buys relative to alternatives at the same stage — not simply whether it is cheapBudget seats meet the same federal standard, so the question is what the premium adds rather than whether cheap is acceptable

Why we publish no star ratings

This is the most unusual thing about the site and it deserves a direct explanation.

There is no published consumer crash score for individual car seat models in the United States. What exists is FMVSS 213 — the pass-or-fail federal standard every seat must meet — plus NHTSA's Ease-of-Use rating and IIHS's booster belt-fit ratings. Those last two are genuinely useful and we point at them constantly.

What we cannot do is reprint them. Both NHTSA's and IIHS's rating databases return errors to automated requests, so no per-model figure could be verified from the primary source. We could copy numbers from secondary websites, and many sites do. On a page a parent may use to choose what protects their child, publishing an unverified or stale safety number is not a risk worth taking — so every product page links the official lookup tool for that exact model instead.

The cost is real: the pages look less authoritative without a number. We think that is the correct trade. Full explanation of what each rating measures is in car seat safety ratings explained.

Imagery, and what it does not imply

Every product photograph on this site is a licensed stock image of the product CATEGORY, not a photograph of that specific model, and every one is labeled 'Category photo' in the interface.

The reason is the same as everywhere else here: we do not have manufacturer image feeds for this site and we do not own the units, so a photograph implying we did would be a small lie in service of a nicer page. Labeling it costs us polish and keeps the page honest. When a real product image feed is available, these will be replaced.

What would change a score

  • A recall naming a model would be added to its page immediately, with the affected manufacture-date range.
  • A specification change — manufacturers quietly revise shell heights and weight limits without changing a model name — would be re-read from the source and re-dated.
  • A published third-party rating we could finally verify would be added, with its source.
  • Discontinuation would move the product out of recommendations and its successor in.
  • A reader correction with a source. These go to the front of the queue — see contact.
  • A live price data layer, once available, would replace 'Check price on Amazon' with a dated figure through the normal price layer rather than hardcoded numbers.

What would NOT change a score: commission rate, brand relationship, or whether a product is in stock. Our editorial policy covers the independence rules, and the affiliate disclosure covers the money.

Frequently asked questions

Do you test the products you recommend?

No, and we will not claim otherwise. We do not run a crash-test lab and we do not own the units on this site. What we do is read each manufacturer's specification page and manual, record every figure against its source with the date we read it, check the recall database, confirm the model is currently sold, and score it against five published criteria.

Why is there no star rating on your product pages?

Because we could not verify one from the primary source. NHTSA publishes an Ease-of-Use rating and IIHS publishes booster belt-fit ratings, but both block automated access to their databases. Rather than reprint figures from secondary sites, we link the official lookup tool for each model. It looks less authoritative and it is more honest.

How is your score calculated?

Five criteria — install, fit range, vehicle fit, daily use and value — each scored out of ten from documented properties, weighted equally into an overall figure. It reflects published specifications and install hardware rather than crash performance, and it is excluded from the page's structured data so it cannot be mistaken for an official rating.

Does affiliate commission affect your recommendations?

No. Our criteria are published, our scores come from documented specifications, and on several roundups the budget option is the top pick. Amazon is currently the only retailer we earn from, so there is no differential commission to bias between retailers. The full terms are in our affiliate disclosure.

How often is the research updated?

Every product carries the date we confirmed it was currently sold and the date we checked it against the recall database, and every specification names the page it was read from. Model lines refresh every few years, sometimes without a name change, so if a page's dates are old, treat the manufacturer's current manual as authoritative over anything here.

What should I do if I find an error?

Tell us, with a source if you have one. Corrections go to the front of the queue and we will name the change rather than quietly editing the page. The contact form has a Correction option in its subject list specifically for this.
