How We Picked the Best Mattress in the UK

Choosing the best mattress in the UK requires more than brand popularity. Our selection process focused on factors that directly affect sleep quality and long-term comfort. We prioritised support, motion isolation, temperature regulation, and verified customer feedback.

Support refers to how well a mattress keeps the spine in natural alignment across different sleep positions. Motion isolation measures how effectively movement is absorbed, which is especially important for couples. Cooling performance helps regulate body temperature and reduce night sweats, a common concern with foam mattresses.

To ensure accuracy, we reviewed independent lab testing, long-term customer reviews, and performance scores from trusted UK organisations such as Which? and Good Housekeeping. This approach allowed us to balance expert analysis with real-world user experience.
