Side sleepers need the shoulder and hip to sink while the waist stays supported. That is a narrower target than the firmness scale suggests, and body weight moves it.
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.
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.
