How do mattresses become Which? endorsed?

Performance

When you're looking for a new mattress, the main aspect that you want it to deliver on is how well it can support you. Without this, you'll never be able to get a good night's sleep! Which? takes into consideration how well the mattress supports you back in the sleeping position that you usually sleep in, the stability of the mattress, breathability and whether the mattress restricts easy movements. Therefore, this looks at the edge support, temperature regulation and pressure relief of every mattress they test. Scoring the mattress on all of these performance parameters makes up 55% of the mattress' total score.

Durability

The key question that Which? as is whether the mattress is designed to stand the test of time. A quality mattress is designed to last at least 7 years, but Which? take it a step further and use technology to assess how a mattress performs under a 10-year simulation. If they're in a similar condition to their original form, they will have passed the durability test. Overall, this accounts for 40% of the test score.

Ease of use

Lastly, for the remaining 5% of the mattress score, Which? explore how easy it is to look after the mattress. We should regularly rotate our mattresses to keep them in good condition, and for double-sided mattresses, we should also flip them often. In order to do this, you don't want the mattress to be without handles or too heavy. Therefore, Which? accounts this into their scoring, albeit at a much less significant level than other components.
