What 5 car seats products score on
We scored 5 products in this category on the same 5 criteria, weighted the same way. That makes them comparable, which lets the set say things no single review can — where products genuinely differ, and where the thing they are all marketed on turns out not to separate them at all.
Where they differ most
Value
Scores run from 2.5 to 4.0 across 5 products — a 1.5-point spread. This is the criterion worth reading closely before buying.
Where they're all much the same
Ease of cleaning
Every product lands between 3.0 and 3.5. A solved problem in this category, and a poor reason to pay more.
Every criterion, across the category

| Comfort and fitHow children travel in it, and how long it stays usable as they grow. | 15% | 3.5 | 3.0–4.0 | 1.0 | 3 |
| SafetyCrash-test ratings and standards met — the reason the category exists. | 35% | 4.2 | 4.0–4.5 | 0.5 | 5 |
| InstallationHow hard it is to fit correctly, which is where most real-world safety is lost. | 25% | 4.7 | 4.5–5.0 | 0.5 | 3 |
| Ease of cleaningCovers, straps and everything that will need washing. | 10% | 3.4 | 3.0–3.5 | 0.5 | 4 |

How this was put together
Each of the 5 products is scored out of five on every criterion above by a named reviewer, with the reasoning published beside each number. The overall figure is those scores weighted by the shares shown.
The scores come from published manufacturer specifications and from what verified owners consistently report across the retailers selling the product. We do not test products ourselves, and no figure on this page should be read as a measurement. What it is instead is a large body of owner reporting and specification, read against one consistent rubric — which is something no individual review can tell you and something the manufacturers will not.
Averages are the mean across products, counting each product once however many reviews it has. A dash means nobody has scored that product on that criterion yet, and it is left out of that criterion's figures rather than counted as a zero.
