How We Test

Sleep Science Review evaluates sleep products by the details that change a buying decision: fit, comfort, materials, return terms, care requirements, durability signals, and value.

• Fit before hype

  Mattresses, pillows, bedding, and masks are judged by sleeper position, room conditions, sizing, and adjustment range instead of one-size-fits-all claims.

• Specifications matter

  We check material disclosures, dimensions, cleaning rules, warranty limits, trial policies, subscription fees, and maintenance cost where those details affect ownership.

• Clear boundaries

  This site covers sleep products and bedroom setup. We avoid diagnosis, supplement advice, treatment claims, and promises a product cannot prove.
