What the score means
Declared quality: built from what each maker states about materials, thermal behaviour, support, function, certification and durability, weighted for blackout curtains. It rewards products that say specifically what they are and what they are made of. It is not a lab test, and a product whose maker states too little to grade is not ranked rather than ranked low. Scores compare blackout curtains only with itself — never a mattress with a pair of earplugs.

Scores rate what a product declares, not how it will suit you. Persistent sleep problems are worth raising with a clinician. Some links are affiliate links; they never affect a score.
