Best mattress sales

Emma The Original foam mattress: 45% off

  • We like: Not too warm to lie on, doesn’t need to be turned, comes with a 200 night sleep trial
  • We don’t like: Softer than you may expect

Our review of The Original is the most popular mattress review on our site. And the current 45% discount is the best deal we’ve seen from Emma this year for this bed-in-a-box mattress.

And it’s been discounted plenty of times across the past year already, including on Black Friday last year and Easter 2021. But this deal, which reduces the usual price (£699) down to £384.45 is the best we’ve seen yet. We saw one which came close (42% off) but you needed to have a special code from social media.

If you’ve been waiting for a good time to buy this mattress, we’d say go for it. The Summer Bank Holiday deal is only available until Monday.

Made from a 19cm foam core, with an additional 2cm layer of memory foam and 4cm of ordinary foam, this memory foam mattress isn’t too warm to lie one.  Which, if the sun shines this bank holiday, could be a bonus. It arrives vacuum-packed in a box to your doorstep, making it ideal if you live somewhere with an awkward stairs to navigate.

It comes with a 200 night trial and despite Emma saying this mattress is medium firm, it ranked as an eight in our independent tests (where one is firmest and 10 softest).

Simba Hybrid mattress: 35% off

  • We like: Comes with a 200-night sleep trial, not too hot to sleep on 
  • We don’t like: Only available-online

Simba’s 35% discount on it’s popular hybrid mattress reduces the price to £571.35 (from £879). We’ve seen a 35% discount before, but we’ve not seen a better offer (yet) this year.

And, with no caveats (at the moment), you can just buy it without needing to spend a minimum amount, a code or being a new customer.

Offering the best of both worlds, the Simba Hybrid combines several layers including a mini pocket-spring layer topped with foam, and a zoned support base beneath.

It’s another bed-in-a-box brand, which means it’s arrives vacuum-packed in a box making it easy to get the room of your choice.

It comes with a 200 night sleep trial.

Jay-Be Benchmark S3 open coil spring mattress: 20% off

  • We like: Affordable, not very heavy, doesn’t need to be turned over
  • We don’t like: It has several different names (making it hard to pin down deals), no sleep trial

This affordable open coil sprung has 20% off at the moment at Argos (called S3 Memory Eco Friendly double), so it’s a bit of a bargain at £192 (reduced from £240).

The Argos newsletter also has £5 off a spend of £40 at Argos online, so you could get this mattress even cheaper if you have the code. There’s no sleep trial with this mattress, but it does come rolled up to make it a doddle to get home.

Don’t be fooled by the name: this mattress is made from a central core of 16cm open coil springs, topped with layers of fibre and matting made from recycled bottles, not memory foam. Jay-Be says this bespoke memory e-fibre makes it a more environmentally friendly choice.

We did find one issue with this otherwise decent mattress, which may bother some.

Eve Sleep Lighter Hybrid mattress: save 35%

  • We like: Comes with a 100 night sleep trial, removable and washable top cover, no need to flip over
  • We don’t like: Feels warm to sleep on, no grip handles to help move it

Eve’s Summer sale runs until 2nd September and it’s offering 35% off mattresses until then, including the lighter hybrid which is one of the cheaper hybrids available. This is a good deal, matching the highest deals we’ve spotted from Eve over the past months. This bring a double mattress down to just £376 (from £579), once again.

The Even Lighter Hybrid is made up of a 10cm pocket sprung core, on top of which sits two layers of foam. This foam can make it feel warm to lie on, but it’s not too soft, with our independent tests rating it average firmness. Not too hard and not too soft: will it be just right for you?

Otty Original Hybrid mattress: 35% off

  • We like: Washable cover, 100 night sleep trial, average warmth to lie on (despite the foam layers)
  • We don’t like:  There’s little bit of a memory effect as you lie on it

You’ll have seen this popular Otty mattress splashed about social media no doubt. This bank holiday weekend Otty is offering 35% off the Original Hybrid mattress, bringing the price down to £487.49 (from £749.99).

This isn’t the highest discount we’ve seen, but, for less than £500, it’s not a bad deal for this mattress.

There’s a lot to this mattress – a 17cm core of micro pocket springs sandwiched between a 4cm foam layer beneath, plus a 3cm foam layer on top of which sits 2cm of memory foam, closest to where you sleep.

Despite all the foam, it’s not to warm to sleep on, but there is a very small memory effect.

Top five things to look for in a mattress

Not sure if you want any of these but confused by the nightmare array of mattress on sale? Our mattress experts take you through the top five things to look for when buying a mattress:

Mattress type

With four main types of mattress, which one you prefer is important: memory foam, foam or latex, pocket sprung, and open coil springs will all have a different feel when sleeping on them. Some may feel warm to sleep on while others may feel cool.

Softness vs firmness

Firmness is subjective and manufacturers describe the firmness of their mattresses in a range of ways.

We use an independent test to rate the firmness of a mattress, rather than say it’s soft or firm. When it comes to firmness, the most important thing is to try a mattress, if you can.

Bed-in-a-box or rolled?

If your bedroom is up a steep flight of stairs, or you live somewhere with awkward corridors then a bed-in-a-box mattress may be just the answer. These come rolled up and delivered in a box, which makes them much easier to move about.

Sleep trials

Many bed-in-a-box mattress come with sleep trails as, usually, you can’t try them out before you buy. Some other brands and retailers also offer mattress sleep trials, or a variation.

Check what’s on offer before you buy, especially if you’re not buying directly, and check all the T&Cs.

Natural fillings

Some mattresses claim to be made from natural fillings, which can be better for the environment than foam or memory foam. There are variations to mattress constructions, though, some will have a token layer while others will mostly be made from wool, cotton or other natural fibres.

Check before you buy, if this is important to you.
