Nearly half of the 15 mattresses we’ve tested this month are good enough to be Best Buys, with one becoming the joint-highest-scoring mattress we’ve ever seen.
New launches from big bed-in-a-box brands, including Casper, Emma and Leesa, have all been repeatedly flipped, pummelled and scrutinised in our tough lab tests.
Three of the most impressive mattresses in our recent tests are from traditional high-street brands that, in recent years, haven’t been in contention for Best Buy recognition.

Online bed-in-a-box mattresses may be all the rage, but there’s still a lot to be said for buying a mattress in store, as our latest test results reveal.
For starters, if you’re after a traditional pocket-sprung mattress with natural fillings, you’re more likely to find that on the high street.
And never underestimate how important it is to try before you buy. Even two mattresses with the same claimed firmness can feel very different from one another.
One of the mattresses we’ve just tested is sold as ‘firm’, but in our own objective firmness tests it ranked as an eight on a scale where one is the firmest and ten the softest.
Below you’ll find brief round-ups of the key features of some of the new high-street mattresses we’ve tested – click through to find out whether they made it as Best Buys.
From understanding firmness ratings to whether to opt for a memory foam or pocket-sprung mattress, find out how to buy the best mattress.
John Lewis Classic Collection Ortho Support 1000 – £399
Classic in every sense of the word, this reasonably priced John Lewis mattress only contains pocket springs and natural fillings, and, unlike many modern mattresses, it’s also two-sided.
But many of the natural spring mattresses we’ve tested sag significantly over time, so you can’t rely on them to be comfortable for years to come.
Read our John Lewis Ortho Support 1000 review to see if it suffers from the same fate.
Sleepeezee Beautyrest Boutique Lexington – £649
Synthetic comfort layers often keep their shape better than natural ones, so in an effort to avoid premature sagging, this one-sided Sleepeezee mattress combines a pocket-spring core with additional foam layers.
But while foam can improve support and longevity, it can also restrict your movement and feel overly warm to lie on.
Read our Sleepeezee Beautyrest Boutique Lexington review to find out if that’s the case with this one.
Not all that long ago, you wouldn’t have dreamed of buying something as expensive and important as a mattress without seeing it in the flesh first.
But the advent of bed-in-a-box mattresses has changed all that – and produced some of the best mattresses we’ve ever seen.
Order either of the mattresses we’ve picked out below and you’ll get 100 nights to sleep on them at home before deciding whether you want to send them back for a full refund.
But although delivery is free, it’s only worth the faff if these mattresses provide good support for your spine, whatever your body size or sleeping position.

Emma Embrace – £649
The Emma Embrace costs more, and has half as many layers, as some of its rivals, but that shouldn’t be a dealbreaker. True, the Embrace only contains three layers of foam, one of which is memory foam, but we’ve been impressed by mattresses that are little more than a single block of foam in the past.
The important thing is whether it will support your spine for years to come, without sagging or softening.

Leesa Sapira – £1,150
Far and away the most expensive bed-in-a-box mattress we’ve tested, the Sapira is also one of the few to contain full-sized pocket springs.
Leesa says that this mattress has been a quarter of a century in the making, provides ‘unparalleled support’ and is both cool to lie on and extremely stable – meaning you shouldn’t be disturbed when your partner rolls over or gets up during the night. But do our independent and objective tests agree?
