There is no best mattress, only the best one for your weight, position and complaint. The problem-to-solution table, our tracked partners, and the five specifications that actually matter.
Almost every mattress is designed around side sleepers. What front sleeping does to the lumbar spine, why firm plus a shallow comfort layer is the answer, and the pillow trick that helps most.
A topper changes the surface, never the support. The 60-second test that tells you which problem you have, which material fixes what, and how thick to go.
Below about £200 a double is a two-year product. Above £700 you are buying finish, not support. Where the money goes, how to spot a bad cheap mattress, and when to spend more.
Three constructions, and every mattress is a variation on one of them. What each is genuinely good at, where the trade-offs sit, and how to choose by your actual sleep problem.
Dust mite allergen is the reason most bedroom allergies flare on waking. What barrier encasements, 60 degree washing and humidity control actually do, ranked by evidence.
Most mattresses are built around a 60-90kg body. What bottoming out, foam density and edge collapse actually mean, and the specifications to insist on above that weight.
Motion transfer is a measurable property of construction, not opinion. Pocket springs versus foam, what to do when you weigh very different amounts, and the cheaper fixes to try first.
Side sleepers put their weight through two narrow points. How to test for a straight spine, what zoned support really does, and why your pillow height matters as much as the bed.
Medium-firm beats firm in the clinical evidence. How to pick firmness by weight and sleeping position, and the five things that matter more than the mattress itself.
Sleeping Express compares mattresses, beds and sleep accessories from retailers we have a verified commercial relationship with. We rank on construction, trial length and returns policy, never on commission rate.
