How We Research

SleepRanked is committed to transparent, research-based recommendations. Here's exactly how we evaluate and recommend mattresses.

Our Methodology

We research mattresses using publicly available information from manufacturers, retailers, and established third-party sources. Our process includes:

1. Manufacturer Specifications

We pull product specifications directly from manufacturer websites whenever possible. This includes construction details, materials, available sizes, heights, and feature descriptions. When a manufacturer provides firmness ratings, we note them as "brand-reported."

2. Verified Pricing

We verify pricing from manufacturer websites as our primary source. When manufacturer pricing is not publicly listed, we check authorized retailers. Every price in our database includes a source URL and a last-verified date. Prices can change at any time — we do our best to keep them current.

3. Trial, Warranty, and Policy Verification

Trial periods, warranty terms, return policies, and shipping information are verified from manufacturer FAQ pages and policy documents. We record the source for each of these data points.

4. Feature Assessments

For qualitative assessments like cooling, motion isolation, edge support, and durability, we rely on a combination of:

• Manufacturer-provided specifications and technology descriptions
• Construction analysis (materials, layer composition, coil types)
• Consensus from established third-party reviews

These ratings are our editorial assessments based on available information, not laboratory measurements.

5. Financing Information

We verify financing availability and providers from manufacturer checkout pages and financing partner information. Terms, rates, and availability may vary and are subject to credit approval.

What We Do NOT Claim

• We do not claim hands-on testing unless explicitly stated otherwise. Our evaluations are research-based.
• We do not use fake review counts or ratings. When we reference ratings, they are clearly sourced.
• We do not use original product photography unless specifically noted. Product images are sourced from manufacturers.
• We do not guarantee that our assessments match your personal experience. Mattress comfort is subjective.

Data Freshness

Every product in our database includes a "last verified" date. We aim to re-verify pricing monthly and specifications quarterly. If you notice outdated information, please let us know.

How We Make Recommendations

Our mattress matching tool uses a scoring algorithm based on your stated preferences. It considers your sleep context, size needs, priorities, budget, and problem areas, then scores each mattress in our database against those criteria. The algorithm is deterministic — the same inputs always produce the same results.

Affiliate Relationships
