About Sleep Science Rankings
Science-first. Transparency always. Better sleep for everyone.
Why We Exist
The sleep industry is worth $432 billion. Most review sites rank products based on who pays the most commission. We rank products against peer-reviewed research from journals like The Lancet, Sleep Medicine, and the Journal of Clinical Sleep Medicine.
Our Methodology
Each product gets a Sleep Score (0-100) based on: number and quality of supporting studies, study design strength (RCTs highest), clinical relevance to measurable sleep outcomes, real-world accessibility, and category-specific factors like thermal regulation or cervical alignment.
Transparency
We use affiliate links. When you buy through our links, we may earn a commission at no extra cost to you. This never influences our rankings — products are scored before any affiliate relationship is considered. Every study we cite links directly to PubMed.
Living Meta-Analysis
Our research page features a living meta-analysis that synthesizes all cited studies into key findings. As new research is published, we update both the individual study entries and the overall synthesis, keeping our rankings evidence-current.
