Baby gear, compared — with the sources attached
We are parents working through the same decisions you are. Every figure on this site comes from the manufacturer’s own documentation, with a link and a date.

How to compare baby gear without taking anybody’s word for it
Two retailer listings for the same stroller will often quote different folded dimensions. Usually nobody is lying: one measured with the seat attached, the other without, and neither said which. That gap — between what a manufacturer publishes and what a seller repeats — is the reason this site exists.
Start from the specification sheet, not the listing
A product page is written to sell. A specification sheet is written by the people who built the thing, and it is the document the manufacturer has to stand behind. When the two disagree, the specification sheet wins. When the specification sheet is silent, that silence is information too.

Four things worth checking first
- Folded dimensions, not just folded height. A stroller that folds flat can still be too long for the trunk you own.
- The weight of the part you actually lift. Some brands publish frame weight, some publish the whole travel system. Those are not the same number.
- What the box contains. Adapters, rain covers and bassinets are often sold separately, even when the photographs show them attached.
- Whether the figure is published at all. A brand that documents one product carefully tends to document the rest the same way.
When a figure is missing
Missing data is not a small thing. If a manufacturer does not publish a measurement, no review can honestly supply it — and a number that appears from nowhere in a comparison usually came from a competitor’s page or from somebody’s estimate.
Here a missing figure is printed as manufacturer does not publish. It is not an omission we forgot to fill in. It is the finding.
What we do not do
- We do not write about feeding, health or safety. Those are regulated subjects where a parent’s opinion is no substitute for a professional.
- We do not publish prices. The programme rules do not allow it, and a hand-copied price is wrong within a week anyway.
- We do not measure anything ourselves, and we never present somebody else’s measurements as our own.
- We do not take payment for placement, and no brand sees a draft before it goes live.
