Top 10 mattresses for 2021
With the quality of your sleep and the support of your spine at stake, do you really want to risk spending a fortune on an unsupportive mattress that won't stand the test of time?
Well, fortunately you don't have to. Our independent and rigorous lab tests have uncovered the best mattresses – and exposed the worst. With more than £100 separating our cheapest Best Buy mattress from our most expensive Don't Buy, a good night's sleep might cost less than you expect.
Whether you’re looking for a pocket sprung or memory foam mattress, you'll want to take a look at our recommendations below. We’ve picked out the highest- and lowest-scoring mattresses that are available to buy in 2021, so you can be sure of buying the best and avoiding the worst.
All of our top 10 mattresses below performed well in our tough body-support and durability tests. But you should always try out the mattress in a shop if you can, because that’s the only way to know whether you will personally find it comfortable

The worst mattresses to avoid
Even if you find these mattresses fantastically comfortable when you try them in the shop, we would advise against adding them to your short list. Comfort doesn't guarantee support or durability, and all three mattresses have serious flaws in at least one of these areas.

How we independently test mattresses
Not only does no one else test mattresses like us, but we’re also totally independent, so you can have complete confidence in our results.
If you tend to sleep on your back, a good mattress will keep your spine in the same shape as when you’re standing. So, we measure the shape of a person's body at 36 different points when standing, and then again when lying on their back on the mattresses, to see how well they compare. If you’re a side-sleeper, your spine should be parallel to the mattress, so we use a laser to measure the angle of a person's spine relative to the bed. Are you a front sleeper? We also measure the spine a third time to assess how supportive each mattress is for people who prefer to lie on their front.
After simulating several years of use by rolling a heavy barrel over the mattress thousands of times, we then repeat the body-support tests to see whether the mattress becomes less supportive over time.
That’s not all. With our results, you can see how breathable a mattress is, how easy it is for you to turn over on and how stable it is. If you’re a light sleeper, you should try and buy a mattress with five stars for stability. These are the best at absorbing bounces, so you’ll be less likely to be disturbed when your partner rolls over or gets up in the night.
