How we choose
Last updated September 21, 2026
The short version
We start with the injury, not the product. For each hazard (a fall down the stairs, a dresser tipping, a hand in the outlet, a cabinet full of cleaners, a window with a screen and nothing else), we read what the CPSC, ASTM and the AAP say actually prevents it. Then we read the manufacturer's page and manual for every product that is sold today for that job, score it on the rubric below, and rank it. Right now that covers 92 products across 64 guides, rankings and comparisons.
We don't lab-test products, and we say so. We have not pulled on these gates with a force gauge or dropped a weight on these anchors. Every big name in this category says “tested”; we compete on something you can check yourself: every spec links to the page it came from, every standard is named exactly (ASTM F1004, not “ASTM certified”), every install condition is quoted from the manual, and the scoring weights are printed on every ranking.
Claims we refuse to make
- Units we claim to have tested: 0. No “after six months on our stairs”, no “in our testing”, no photos presented as our own installs. Photos on this site are stock and are labeled that way.
- Sponsored placements: 0. No brand can pay for a rank, a mention or a change to a write-up.
- Prices shown without verifying: 0. We only show a price when it comes from a live, recent retailer data feed. Until then every button says “Check price on Amazon”, because a remembered price is usually a wrong price.
- Certifications we assume: 0. If a manufacturer's page does not state a standard, the card says “no standard stated” and the product loses points for it. We never infer JPMA or ASTM from a logo on a box we have not seen.
- Promises of safety: 0. A gate lowers the chance of a fall; it does not make stairs safe. Every page that touches water, windows, fire or tip-over carries a supervision note, and we mean it.
The scoring rubric
Each product gets six sub-scores from 0 to 10. The overall score on a page is the weighted average, rounded to one decimal. The sub-scores belong to the product and stay the same everywhere; the weights change with the page, because reversibility matters more in a rental than at the top of a staircase.
| Metric | What it measures (published sources only) | Default weight |
|---|---|---|
| Standards & certification | Whether the manufacturer or listing states compliance with the standard that applies: ASTM F1004 and 16 CFR 1239 for gates, ASTM F2057 (the STURDY rule) for dressers, ASTM F3096 for anchors, ASTM F3492 for cabinet locks, ASTM F2090 for window guards, ASTM F2208 for pool alarms, UL listing for outlet covers, plus the JPMA / Baby Safety Alliance mark where present. Stated by the maker, never assumed. | 25% |
| Installation truth | What it actually takes: stud or no stud, drilling or adhesive, cure time, adapters sold separately, and how honestly the listing says so. A product whose manual contradicts its box scores low here even if the product is good. | 20% |
| Toddler resistance | How the mechanism defeats a determined 18-month-old, from the published design (two-motion releases, decoy buttons, height, stop pins) and aggregated owner reports, which inform an observation but are never quoted as our finding. | 20% |
| Adult one-hand use | Whether an adult can open, close and re-lock it with a baby on one hip. A product that is annoying gets removed, and a removed product protects nobody. | 10% |
| Damage & reversibility | Holes, adhesive residue, damage to finishes, and whether a renter can take it with them. | 10% |
| Value | Price band against how many you need. A $20 pack of thirty latches and a $150 hearth gate are both fair value for their job; a $30 pack of four is not. | 15% |
A missing spec is scored neutral (5), never guessed. If a brand doesn't publish a height or a load rating, the page says “not published”. A missing standards statement is the exception: that is scored low on purpose, because it is the one thing a safety product should never leave out.
Weights change with the page
At the top of the stairs the standard and the install are everything and reversibility is nearly irrelevant. In a rental it is the other way around. So each ranking uses one of these weightings and prints it in its “How we chose” box.
| Weighting | Used on | Standards & certification | Installation truth | Toddler resistance | Adult one-hand use | Damage & reversibility | Value |
|---|---|---|---|---|---|---|---|
| Default | Most roundups and comparisons | 25% | 20% | 20% | 10% | 10% | 15% |
| Critical | Top of stairs, window guards, furniture and TV anchors, pool barriers | 30% | 30% | 20% | 5% | 5% | 10% |
| Rental | No-drill, apartment and banister pages | 20% | 20% | 15% | 10% | 25% | 10% |
| Bulk | Outlet covers, cabinet locks, corner guards: things you buy twenty of | 20% | 15% | 25% | 15% | 5% | 20% |
| High traffic | Kitchen and hallway gates, doors you open fifty times a day | 25% | 20% | 15% | 20% | 5% | 15% |
| Gift | Gift guides, where you don't know the recipient's walls | 20% | 15% | 15% | 20% | 10% | 20% |
Where our information comes from
We use the highest-quality source available, in this order:
- Regulators and standards bodies: the CPSC (16 CFR 1239 gates, the STURDY rule, the Anchor It! campaign and its annual tip-over reports), ASTM International (F1004, F2057, F3096, F3492, F2090, F2208, F2286), the NEC via ESFI (tamper-resistant receptacles), and UL listings.
- Medical and injury-prevention bodies: the American Academy of Pediatrics (HealthyChildren.org), Safe Kids Worldwide, and the CDC. We read the page before we cite it.
- Manufacturer documentation: the product page, the manual and the spec sheet, for opening ranges, heights, mount type, adhesive cure time, stud requirements and stated certifications. When the box contradicts the manual, we quote the manual; that is most of the “installation truth” on this site.
- Named retailer listings (Amazon, Ace, Lowe's, Walmart) only when the brand doesn't publish a spec, and labeled as retailer-listed.
We don't cite other review sites' opinions or test results as fact, forum claims, or Amazon star ratings and review counts.
How we check a product is actually for sale
Every pick is a current model we confirmed on the brand's site or a major retailer on the date shown on the product card, and every buy button is a search on Amazon.com for that exact model. When a brand renames a model (Summer Infant's banister gate is now sold as the Ingenuity Stairway+), the page names both so you can find it either way.
“Skip it if”
Every product card says who should not buy it, and every card states the one thing the listing leaves out about installing it. A recommendation with no stated downside reads like an ad, and the right answer for a lot of babyproofing questions is “you may already have this”: a post-2008 house probably has tamper-resistant outlets, and a dresser that is already anchored does not need a second strap.
How often we update
- Roundups and comparisons: monthly availability check; every pick is still sold or it is replaced.
- Standards explainers: quarterly, and within 30 days of a CPSC rule or ASTM revision.
- Room and stage guides: every six months, against current AAP and CPSC guidance.
- Prices: daily and automatically, once live price data exists; until then no price is shown.
A page's “Updated” date only changes when its content really changes, and every change is logged in the page's “What changed” section.
