How good are the latest Emma mattresses?

We've pitted the latest Emma mattresses - the Diamond Hybrid and the Helix Hybrid - against big brand mattresses from brands such as Otty and Eve Sleep

What do the new Emma mattresses have to offer, and is it worth spending over £1,000 on one of them?

If you've been looking into buying a new mattress, you've undoubtedly come across popular mattress brand Emma. Its Original mattress is the most popular mattress on the Which? website.

Emma has launched two new bed-in-a-box mattresses: the Diamond Hybrid and the Helix Hybrid. The Diamond Hybrid costs £1,669 and the Helix Hybrid is a bit cheaper - though still by no means cheap - at £1,329 full price.

So what exactly do you get for your money? And do you need to pay so much for a mattress?

Emma bed-in-a-box mattresses

Emma is best known for its bed-in-a-box mattresses: mattresses that arrive vacuum packed and expand once you open them.

So that means that you don't have to worry about how to get the Diamond Hybrid or the Helix Hybrid home or in through your front door.

The Diamond Hybrid and Helix Hybrid are also hybrid mattresses, made from a mixture of layers of foam and pocket springs.

Normally, you can only buy Emma mattresses online. But you can buy the Diamond Hybrid and the Helix Hybrid in-store from a number of retailers, including Furniture Village, Land of Beds and independent stores.

Buying in-store means you get to try the mattress out before you commit to buying, if you want to get a feel for how comfy it will be when you first use it.

Just be aware that this won't tell youhow long it will last, or if it will sag or soften over time - head to our fully tested mattress reviews to find out about that.

Emma Diamond Hybrid double mattress, £1,669 (RRP)

Emma Diamond Hybrid review
  • We like Available in shops, doesn't need to be turned over, 100-night trial, cover is washable
  • We don't like Slight memory effect when lying on it - which some people may not like, expensive when it's at full price

The Emma Diamond Hybrid mattress is formed of layers of foam and pocket springs, including a 13cm core of pocket springs and a 3cm layer of memory foam closest to where you sleep.

Full retail price is given as £1,699 which makes it one of the most expensive Emma mattresses available.

Emma claims this mattress is medium firm. But, in our own independent tests, we rated it as 7.1 on a scale from one (firmest) to 10 (softest). So it's actually on the softer side of medium.

Mattresses made with foam can sometimes feel warm to lie on, especially ones with a memory effect. We found this one to be about average when it comes to warmth though.

If you're looking for a a mattress that isn't too hot or cold to lie on, take a look at the Eve Premium Hybrid £734, or the MattressOnline Horizon Discovery 1500, £367, which are also medium-warm.

The Emma Diamond Hybrid is currently cheapest at Land of Beds where you can pick it up from £799.

Emma Helix Hybrid mattress, £1,329 (RRP)

Emma Helix Hybrid mattress
  • We like Available in shops, doesn't need to be turned over, 100-night trial, cover is washable
  • We don't likeIt could be easier to move around, expensive when it's full price

The Emma Helix Hybrid mattress is almost identical to the Diamond from the outside, but it's constructed differently.

The Helix has a 12.5cm core of pocket springs topped with two different layers of foam, including a 3cm layer of foam nearest to the surface you sleep on. The Helix also has fewer springs per square meter and is lighter.

Full retail price is given as £1,329 which means it joins the Diamond hybrid as one of the most expensive Emma mattresses in its range.

Emma claims this mattress is medium firm, and our own independent testing agrees. We ranked it as 5.4 on a scale from one (firmest) to 10 (softest), which is similar to the popular Otty Aura, £700, or the significantly cheaper Ikea Morgedal memory foam mattress, £179.

We also class this mattress as average warmth, which means it's suitable for most people.

We put each mattress we test through tough durability tests, designed to replicate 10 years of use. Read our full test review of the Emma Helix Hybrid mattress to find out how it fared.

It's also available on offer at the moment from Land of Beds (£649) and at a range of independents.
