Hands-on testing
We only write “tested by Sleeple” when a product has genuinely been handled and used by the team under a described protocol. Otherwise we never imply that a hands-on test occurred.

How Sleeple evaluates products
A useful recommendation should state what was actually verified. Sleeple consistently separates hands-on testing, documentary analysis, scientific evidence and manufacturer claims.
Independence principle.
Some links may be affiliate links. Sleeple may receive a commission at no extra cost to you. Compensation does not determine our criteria, conclusions or comparison order.
Documentary review
We verify relevant specifications in manufacturer or retailer documentation: dimensions, materials, battery life, subscriptions, care, warranty and returns. Marketing copy is not treated as proof of efficacy.
Scientific evidence
When a product claims an effect on sleep, we look for relevant studies and guidance. Evidence about a product category is kept separate from evidence validating an exact model.
Commercial data
Prices, availability, warranties, trials, returns and subscriptions can change. We date these details when they matter and avoid presenting a price as permanent.
What “best” means on Sleeple
We avoid universal rankings when the right choice depends on the user. A product may better suit side sleepers, travel, hot sleepers or sports recovery without being “best” for everyone. Comparison criteria should therefore be stated before products are presented.
What we do not do
- invent tests or measurements;
- turn manufacturer claims into established facts;
- hide affiliate relationships;
- create fake scarcity or fake discounts;
- promise unsupported medical benefits;
- change rankings because one programme pays more.
Updates and corrections
Products, prices and scientific evidence change. When we identify a factual error, we correct it. To flag an issue, use our Contact page.
