It’s no wonder January is one of the most popular times of the year to buy a new mattress.
If you want to start the new year with a spring in your step, a new mattress can be a great way to improve your sleep quality. And, if you know where to look, there are some huge savings on mattresses to be had at this time of year.
Not all deals are as good as they seem, though, which is why we’ve rounded up deals on the most popular mattresses below, as well as showcasing new mattresses to look out for in 2020.
See our full list of Best Buy mattresses.
Deals on the most popular mattresses
The three most popular mattress reviews on our website over the past month all come from bed-in-a-box brands offering 100-night sleep trials.*
Two of them are currently running tempting-looking promotions for the January sales.
Emma mattress deal, £389 — saving £260 (40%)
Emma is one of the best-known mattress brands. It has been advertising some huge discounts recently, so it’s perhaps no surprise that more people read our review of the Emma Original mattress than any other in the past month.
Emma had a massive 45% discount running in late December, but its current offering of 40% off is still well worth considering. It’s the same as the brand’s Black Friday saving. Using the online checkout code JAN40 you can save more than £250 on the Emma Original, taking the price down to £389 for a double.
But is it the right mattress for your body size and sleeping position? Read our Emma Original mattress review to find out.
Eve mattress deal, £679 — saving £170 (20%)
While the percentage saving isn’t as good as Emma’s, you can still end the month with a very healthy saving on our second-most popular mattress — the Eve Premium Hybrid.
This high-end mattress combines pocket springs and memory foam and usually costs £849, but is currently available on Eve’s website for £679 for a double.
Read our Eve Premium Hybrid review to find out how warm it feels to lie on and whether it will sag over time.
Casper mattress, £320 — saving £80 (20%)
Our review of the Casper Essential mattress was the third-most popular over the past month. And, until 13 January, you get 20% off using the code SWEETDREAMS, taking the price down to a tempting £320.
It has a more basic structure than either the Emma or the Eve mattresses above – it’s made using just two foam layers of different densities. But that’s not necessarily a bad thing. In our labs, we’ve found that some of the most basic mattresses provide better support than some of the most expensive.
Read our Casper Essential mattress review to see how it fared in our lab tests, and whether it’s worth buying.
New mattress reviews for 2020
The decade is only a few days old, but we’ve already reviewed 10 new mattresses, the best of which are long-lasting enough to see you right through to 2030, according to our durability tests that simulate 10 years of use.
But while two of the new mattresses were good enough to earn our Best Buy seal of approval, four left us disappointed.
Ikea Hafslo mattress, £80
Just when we thought we had tested the cheapest mattress that Ikea had to offer (Ikea Malfors, £100), an even cheaper one came along.
Your eyes don’t deceive you — the Hafslo really is just £80 for a double spring mattress. It’s extremely light and feels cooler than most to lie on, thanks to its open spring structure, but how does it stack up when it comes to providing your spine with long-lasting support?

Mattress Online Horizon Apollo, £304
If you tend to feel cold during the night, this reasonably priced memory-foam mattress from Mattress Online is likely to be a better bet for you than the Ikea mattress above.
It feels warmer than many to lie on, partly because the memory foam moulds to your body shape and retains your heat.
Slumberland Ortho Firm 800, £332
If you’re looking for a natural pocket-sprung mattress towards the firmer end of the scale, this Slumberland mattress may be just the one.
Unlike many modern mattresses, both sides of the Slumberland Ortho Firm 800 can be slept on and it doesn’t contain any foam or memory foam.
