How we research & rank
Our methodology
Every score on this site is a judgment from documented research against a published rubric — not a measurement we took in a lab, because we do not have one. Here is exactly what we do, so you can repeat any of it.
We do not lab-test units.We do not own a wobble rig, a formaldehyde chamber or a force plate, and we will never write "in our testing" as if we do. What we do instead is verifiable end to end — that is the point of publishing it.
1. Specs compiled from primary sources
Height range, weight capacity, motor type and count, duty cycle, transit speed, warranty length, and the material of the top and frame — all taken from the manufacturer's own spec sheet and manual, and cited with a link. Where a manufacturer is vague (a common tell on cheaper desks), we say the spec is unstated rather than guessing.
2. Certifications verified at the registry, not the marketing page
This is the step almost nobody else does. A "GREENGUARD Gold" badge on a product page is a claim; a certificate in UL's SPOT database is a fact. For each model we check:
- GREENGUARD / GREENGUARD Gold in the UL SPOT registry (Gold is the stricter, low-emission tier suitable for schools and healthcare).
- BIFMA level and the specific durability/safety standard cited (e.g. ANSI/BIFMA X5.5 for desks).
- CARB Phase 2 / TSCA Title VI compliance for composite-wood emissions.
- FSC for wood sourcing and UL Formaldehyde-Free where claimed.
If a brand claims a certification we cannot find registered, we do not repeat the claim as fact — we note that it is unverified. See the certification matrix for the per-model result.
3. Cost-to-own arithmetic
Sticker price is the wrong number. We normalize it against warranty years, the availability of replacement parts (a desk is a motor and a controller that will eventually fail), and the realistic lifespan of the mechanism. A desk that costs more but carries a longer warranty and sells spare parts frequently costs less to own.
4. Material-safety reasoning
Engineered wood versus solid wood, laminate and adhesive off-gassing, the powder-coat on the frame, and — for mats — polyurethane versus PVC foam and where PFAS can hide in a coated surface. We also publish a documented first-72-hours off-gassing expectation — described and reproducible, and honest that it is guidance, not a chamber measurement.
5. Buyer-first ranking
Products are ordered by fit for the health-and-safety buyer — certification, materials, and pain-appropriate ergonomics — never by what pays us most. This is why a direct-only desk that earns us nothing can finish first, and why a cheaper mat can beat a premium one.
The scoring rubric
Each product is scored out of 10 on four to six category-appropriate metrics (for desks: stability, adjustment range, materials & certification, build & motor, value). The overall score is the mean of those metrics. The stars you see are a visual of that number — they are our editorial score from this rubric, not customer ratings, and they never appear in our structured data as a review rating, because that would be a signal we did not earn.
What we explicitly do not do
- Operate a test lab or physically stress-test any product.
- Claim to have used a unit we have not used.
- Invent prices, ratings, review counts or certifications.
- Let a commission rate change a ranking.
Saying this plainly is a trust asset, not a weakness. If you find anything on this site that contradicts it, tell us and we will fix it.
