Our latest tests saw the new Emma mattress pitched against other online-exclusive mattresses from Next, Made.com, Ergoflex, Sleepbear and Uno.
Three of the 10 new mattresses we tested earned our coveted Best Buy recommendation. One really impressed in our independent tests and achieved a chart-topping score of 79%, 27 percentage points higher than the worst we’ve found this year.
Read on for our round-up of the latest mattresses we’ve tested, or head to our full list of Best Buy mattresses to see the new winners.
How does the new Emma mattress stack up?
We tested the original Emma Hybrid mattress back in 2017, but this year the popular online brand has launched a new (and hopefully improved) mattress. Confusingly, it’s called the Emma Original, or the 2nd Generation Emma.
The new model ditches the extra layer of individual conical pocket springs used in the older version, opting instead for a series of layers of the brand’s trademarked Airgocell foam, pressure-relieving viscoelastic memory foam and supportive cold foam.
Like many online mattress brands, including Casper, Leesa and Simba, Emma delivers the Emma Original mattress to your door vacuum-packed and rolled up in a box. It comes with a 100-night trial, during which you can choose to return it for a full refund. At £649, it’s not the cheapest mattress we’ve tested, but it’s a cheaper option than many traditional pocket-sprung alternatives.
Other brands have made updates to their bed-in-a-box mattresses before – some remained fairly unchanged in our test results, while others actually fared worse than their originals.
But has the new Emma Original bucked this trend and wowed in our lab? Read the full Emma Original review to find out.
New mattress reviews
Ikea Hidrasund mattress, £649
Ikea sells a wide range of mattresses, from budget foam options like the £165 Ikea Morgedal, up to more premium options, such as the Hidrasund.
The Hidrasund is currently Ikea’s most expensive mattress, although at £649 it’s similar in price to those from online competitors. However, unlike online brands, which tend to go for unique combinations of different types of foam, the Hidrasund is made with more traditional pocket springs and natural fibres.
It has a thick top layer of natural latex, wool and cotton to provide comfort. Ikea claims that it is made entirely of organic materials, to provide a healthier sleep environment.
Read our full Ikea Hidrasund review to find out whether its classic approach has created a breathable and supportive mattress that will last without sagging for years to come.
Next Aloft mattress, £450
The mattress market has been disrupted in recent years by new start-ups that cut out the need for a showroom and ship mattresses straight to your door in a vacuum-packed box.
It comes as no surprise that established home brands eager to keep up have introduced their own rival bed-in-a-box mattresses in response – Silentnight has brought out the Silentnight Studio (£599), and now Next has joined the fray with its new Aloft (£450).
Like the Emma Original and other bed-in-a-box mattresses, the Aloft arrives on your doorstep rolled up and vacuum packed, with a trial period during which you can return it for a full refund. At 101 nights, it’s one of the longest trials on the market (albeit only by one extra day).

Swoon Lyndhurst 2000 mattress, £699
If you prefer the more traditional feel of pocket springs and natural fibres, the Lyndhurst 2000, from online retailer Swoon Editions, could be a good modern alternative. It comes with a 100-night trial, during which you can return it for a full refund, and a five-year guarantee.
Swoon claims that it is handmade in Hampshire from eight layers of wool, cashmere, silk and cotton, encasing individual pocket springs.
At 60kg, it isn’t light, which may make it particularly difficult to rotate and turn. Swoon recommends that you rotate it weekly for the first four months, then monthly after that. A two-man delivery service, to a room of your choice, is included in the price.
Many other premium, hand-made, pocket-sprung mattresses cost well over £1,000, so this one seems like a steal. But we sent it to our independent lab to find out whether it’s worth it. Read our full Swoon Lyndhurst 2000 mattress review to see how it scored.
