Methodology: verify and cite, not scrape blindly.

Massage chairs cost $400–$8,000. Most review sites cover this category with affiliate-rate ranking, fake hands-on reviews, and marketing-copy specs. We don't. Here's how ChairClarity is built — and where to push back if a recommendation looks wrong.

Six principles

  1. 01

    Verify and cite, not scrape blindly

    Every spec we publish has a source URL, a verification status, and a last-checked date. Manufacturer pages and manuals beat retailer copy. Marketing claims beat nothing.

  2. 02

    No fake hands-on testing

    We have not personally tested every chair on this site. Where we have, we say so. Where we haven't, we say that too. The advisory layer is verified spec rigor + buyer-fit math — not invented owner stories.

  3. 03

    Comfort, not treatment

    Massage chairs are comfort devices. Where pain, sciatica or mobility comes up, we add a reviewer line, primary citations, and a clinician disclaimer. We do not make medical claims.

  4. 04

    No paid placement

    Brands cannot pay to be ranked, included, or featured. Affiliate links exist and we disclose them above every comparison table. Ranking is by buyer fit, not commission rate.

  5. 05

    Source priority, in order

    1) Official manufacturer pages, manuals, warranty pages. 2) Approved direct-affiliate feeds. 3) Compliant marketplace API access where available. 4) Manual verification on retailer listings when API access is not available. 5) Authorized-retailer pages. 6) Web-search source discovery. 7) AI-assisted normalization, never as sole source of truth.

  6. 06

    Every claim has a date

    Specs drift. Brands rebrand. We mark each row with last_verified and re-sweep high-traffic pages weekly. Anything older than 12 months goes pending verification.

From source to spec

The seven-step verification process

  • 1
    Discovery

    Search and SERP audit finds official manufacturer pages, manuals, warranty PDFs, and authorized-retailer listings for every chair we track.

  • 2
    Fetch

    Public pages allowed by site terms and robots, approved feeds, or APIs only. No automated Amazon page scraping. Login-gated pages are off-limits.

  • 3
    Parse

    Structured-document extraction pulls verified fields from manuals and spec sheets — dimensions, height ranges, weight limits, recline clearances, warranty terms — into normalized rows.

  • 4
    Normalize

    AI-assisted normalization standardizes units, terms, and label variants across brands. Never the sole source of truth — every value lands in front of a human.

  • 5
    Verify

    A human approves every row before it becomes recommendable. Conflicts between sources are resolved to the conservative value or marked 'pending verification' until the conflict is resolved.

  • 6
    Cite

    Source URL and last-verified date are stored for every buyer-facing claim and shown on product cards. Specs without a verifiable source don't ship.

  • 7
    Refresh

    Weekly spec sweep on high-traffic pages, change-triggered re-verify otherwise. Anything older than 12 months goes back to 'pending verification'.

YMYL trust layer

Pages that touch back pain, sciatica, mobility or "is this good for me" carry an additional review layer: a credentialed medical reviewer, a named author byline, two or three primary citations (Mayo, Cleveland Clinic, NIH or peer-reviewed), and a clinician disclaimer near the intro. The reviewer's name, credentials and last-reviewed date are emitted as schema.org Article / MedicalWebPage on every YMYL-flagged URL.

Medical review by a licensed clinician — pending contract.
Until contracted, all YMYL pages are edited by the ChairClarity editorial team. How we work →

If something looks wrong

Email corrections@chairclarity.com with the page URL, the disputed spec, and a source. We respond within 48 hours and log every correction publicly in our verification changelog.

Trust through transparency

Start with the calculator.

The methodology compresses into a 4-question form. Run it once and the rest of the site filters to your fit profile.
