Whether you sleep with a partner, or you just like to sprawl out during the night, you’ll want to buy the best double mattress you can afford for the utmost comfort and support.

The issue is, with the ever-growing popularity of the bed-in-a-box market, there’s a massive range of mattresses to choose from – not to mention different mattress types, from traditional pocket-sprung models to memory foam and hybrid mattresses (we recommend you check out our in-depth guide to mattress types if you’re struggling to decide which is best for you).

Thankfully, we’ve tested a lot of mattresses here at Expert Reviews (many of which have been doubles) so that we can provide you with the best impartial buying advice.

How to choose the best double mattress for you

How big is a double mattress?

To be big enough to fit two people, a standard UK double mattress measures 135cm wide and 190cm long.

By comparison, a single is 90cm wide, while a king size mattress is 150cm wide and a super king 180cm. Length wise, the difference isn’t as significant: a single also measures 190cm long, while a king and super king are both 200cm.

Some retailers and manufacturers will also offer their mattress in a ‘small double’ size, which is reasonably self-explanatory. A standard small double measures 190cm long, with a slightly smaller width of 120cm.

How much should I spend on a double mattress?

It goes without saying that the more you’re willing to spend on a mattress, the more comfortable it’s likely to be. And considering the sheer amount of time we spend in bed, we’d argue that it makes sense to invest in a decent one.

Many of our favourite foam mattresses (including the Emma Original and Nectar mattress), will cost you around £700 in a size double, while hybrid mattresses combining springs and foam tend to be a bit pricier.

The most expensive mattresses, however, which are often deeper and more sumptuous, can easily set you back upwards of £1500. Examples include the Simba Hybrid Luxe and the Tempur Original Supreme, which cost £1,699 and £1,799 respectively. If you’re after luxury from your mattress, these are the prices you’ll be looking at.

That said, you don’t need to spend thousands of pounds for decent comfort and support, and there are plenty of good budget double mattresses available, such as the Silentnight Studio Eco at (£419) and the Dormeo Memory Plus, regularly on sale for as little as £250.


How we test mattresses

Without sounding too obvious, we test our mattresses by sleeping on them. While it seems like a cushy job, there are a variety of factors we take into consideration. With the inclusion of comfort and support, we focus on firmness and temperature control – though, when necessary, we will also pay attention to motion isolation and edge support.

For instance, when considering temperature, all-foam mattresses will retain heat more so than others, which would make them a less suitable option for those prone to overheating.

The foundation on which your mattress lies – whether it’s a divan base, sprung slatted bed or even the floor – will play its part in how a mattress feels beneath you. And although we can’t regularly test multiple bed bases when reviewing a mattress, we will always take this into account.

Before we make a final judgement, we take any trial runs that might be on offer into account – which is often the case within the bed-in-a-box market – before asking the important question, is the product good value for money?

Buying a mattress isn’t an easy task, so it’s worth doing plenty of reading before making the plunge. If you still have unanswered questions, below are a few of our guides and best buys that should help answer them:


The best double mattresses you can buy in 2024

1. Emma Original: Best memory foam mattress for couples

Price when reviewed: £499 (double)| Check price at EmmaUPDATE: Since publishing our review, Expert Reviews has noticed several negative customer reviews for Emma Sleep on Trustpilot, with many customers complaining of shipping delays and a lack of communication. Emma tells us that the brand is working on resolving these issues, and estimated delivery times on its online store have been updated accordingly.


Emma’s Original mattress is made up of three layers of memory foam, plus a breathable top cover which can be removed and machine washed. When we tested it, we found it to be a very versatile memory foam mattress which was more than capable of accommodating a variety of sleeping positions.

Indeed, whether you sleep on your back, front, side, or a combination of the three, the Emma Original is a comfortable and supportive mattress. Thanks to this versatility, it’s a great choice for couples who might be struggling to compromise on sleeping positions.

Needs turning?No
SizesEight sizes from single to super king
Warranty200-night trial, 10-year warranty

2. Simba Hybrid Pro: Best for staying cool

Price when reviewed: £1,299 (double) | Check price at Simba

The Simba Hybrid Pro is constructed from foam with two layers of pocket micro springs (that’s one more than the regular Hybrid). The real winning feature, however, is the upper layer of British wool which rests on top of the mattress’ open-cell foam layer. This is a naturally breathable material which keeps you cool and comfortable throughout the night.

At £1,229 for a double, it isn’t cheap. Despite this, it’s by no means the brand’s most expensive mattress. The Hybrid Luxe adds an extra layer of springs but will set you back an extra £530 for a double, and Simba’s latest premium offering, the Hybrid Ultra, adds yet more springs and layers of foam, but more than doubles the price of the Pro to £2,900 for a double. That being said, the Hybrid Pro remains one of the best hybrid mattresses we’ve ever tested.

3. Origin Hybrid mattress: Best double mattress for support from edge to edge

Price when reviewed: £619 (double) | Check price at OriginBed with Origin Hybrid mattress in bedroom

Origin’s Hybrid mattress really impressed us with its edge support, which means it gives you the optimum balance of comfort and ergonomic support right across the sleeping surface. If you share your double bed, this consistent support maximises the amount of comfort you can both enjoy, rather than having it taper off as you move towards the edge of the mattress.

Like many newer, premium hybrid mattresses, the Origin Hybrid features a grid layer that’s designed to optimise back support, plus a temperature-control layer to keep you cool while you sleep. There’s also a solid foam layer for extra support where it’s needed, and a layer of pocket springs whose innovative design offers better and better support the further you sink into the mattress.

4. Eve Premium Hybrid: Best double mattress for light sleepers

Price when reviewed: £1,249 (double)| Check price at Eve

Eve now has no fewer than seven mattresses in its range, and the Premium Hybrid is its best (and most expensive) model yet. Constructed from five layers of memory foam and full-size pocket springs, it’s 270mm deep (which is 20mm deeper than Eve’s Original Hybrid).

The Premium Hybrid is brilliantly comfortable and supportive, and it does a great job of keeping you cool throughout the night. Not only that, but we also found it to be very effective when it came to reducing motion transfer. As such, it’s a great mattress for light sleepers as well as couples who move around a lot during the night.

What’s more, Eve has increased its trial period, offering customers a full year to test out its mattresses. Previously, the only brand to offer such a lengthy trial was Nectar. You can read more about this year-long trial on Eve’s website.

5. Tempur Original Supreme: Best luxury memory foam mattress

Price when reviewed: £1,750 (double) | Check price at Bensons for Beds

Tempur is renowned for its quality memory foam mattresses and bedding, and the Original Supreme is no exception. It’s an extremely comfortable mattress that will mould to your body while providing excellent levels of support.

But such premium memory foam comes at a high price. In fact, the Tempur Original Supreme is one of the most expensive mattresses we’ve reviewed. Fortunately, like many brands, Tempur offers a 100-night trial period (at the end of which you have the option of returning your mattress for a full refund if it is not right for you) as well as a 10-year guarantee on its mattresses.

6. Nectar Essential Hybrid mattress: Best double mattress with a lifetime guarantee

Price when reviewed: £650 (double) | Check price at Nectarnectar essential hybrid mattress on an upholstered bed frame, on a grey backgroundNectar’s Essential Hybrid undercuts many of its bed-in-a-box rivals on price, making this 25cm six-layer mattress one of the cheapest hybrids we’ve reviewed. Our tester found this medium-firm mattress offered comfort and support in excellent measure, as well as good motion isolation to give you some peace from a fidgeting partner.

Best of all, Nectar’s trial period and warranty are unbeatable. Not only do you get a full year of sleeping on your mattress to decide whether to keep it, but you also get a lifetime guarantee against faults – in their words a “forever warranty” – so if you’re looking for a mattress to last for the foreseeable future, this could be the one.

7. Emma NextGen Premium: Best hybrid double mattress for value

Price when reviewed: £709 (double) | Check prices at Emmaemma nextgen premium mattress on a bed frame in bedroom

UPDATE: Since publishing our review, Expert Reviews has noticed several negative customer reviews for Emma Sleep on Trustpilot, with many customers complaining of shipping delays and a lack of communication. Emma tells us that the brand is working on resolving these issues, and estimated delivery times on its online store have been updated accordingly.


Emma’s NextGen Premium mattress has fallen in price since we first reviewed it, during the height of summer 2023, and you can now snap up a double for £709 – and that’s before you take into account Emma’s occasional discount sales. What hasn’t changed, though, is the skin-friendly comfort and breathability that so impressed us when we tested it during that heatwave.

Thanks to an innovative combination of large, super-supportive pocket springs and assorted layers of foam, the Emma NextGen Premium achieves a rare feat among hybrid mattresses: it actually lets the air move, so you avoid overheating. The removable cover is another masterstroke, wicking sweat from your body and washing clean in time for the next sleep.

The mattress is quite firm and doesn’t include an active cooling surface like some, but it masterfully avoids the clamminess you get with some foam or hybrid mattresses.

8. Hypnia Supreme: Most luxurious hybrid double mattress

Price when reviewed: £1,500 (double) | Check price at HypniaBed with Hypnia Supreme mattress in bedroom

While all-foam mattresses can be great for side sleepers because they have plenty of “give” for the contours of your hips and shoulders, they sometimes lack the ergonomic support and durability you also need for a proper night’s rest. Not so with this premium mattress from Hypnia, which offers a superb level of support from edge to edge.

Supreme by name, Supreme by nature – and Supreme by price too, as this mattress is certainly an investment, with a double priced at £1,500 when it’s not being treated to one of Hypnia’s fairly regular discounts. However, it does feel like a mattress that will last for many years without sagging, and it comes with a generous 15-year guarantee from Hypnia – that works out to £100 per year, which isn’t a bad deal for such a supremely comfortable sleep.
