How we test
01Construction and terms

Every mattress guide lists layers, materials, trial length and warranty terms from the brand, so you can compare like with like.

02A clear verdict

Each guide says who the product suits, who should look elsewhere, and what to check before you buy.

03No paid placements

Brands cannot buy a review or a spot on a list. Partner codes save you money; they never decide what we recommend.

04Kept current

Prices are dated, codes are updated across the site at once, and pages are revised when a product, standard or rule changes.
