Bed-in-a-box brand Eve Sleep has increased it's sleep trial offer from 100 nights to a full year, beginning from the day your mattress is delivered.
This makes it one of the longest sleep trials available on the mattress market, matching the 365-day trial already offered with Nectar (and sister company Dreamcloud) mattresses. It's getting on for twice as long as the next longest from Simba and Emma mattresses, both of which give you a 200-night sleep trial.
Unlike mattress warranties, which only cover faults, mattress sleep trials let you return a mattress within the trial period if you simply don't like sleeping on it.
But not all sleep trials are the same, and some have strings attached. Find out more below and compare sleep trials from some of the longest on offer. And, if you're in need of a new mattress, we've outlined the key features of the most popular mattresses from top brands.
Looking for a high-quality mattress that will stand the test of time? Discover the best mattresses we've tested.
Sleep-trials, commonly offered by online-only, by bed-in-a-box mattress brands, allow you to trial a mattress to see if it is the right one for you. If you don't like it, you can return it within the specified trial period. This can be perfect if you want to try a different type of mattress but aren't certain it'll be right for you.
Eve Sleep is one of only a handful of brands to offer a trial of a full year, though. Mattress sleep trials from other brands and retailers can start from just 30 days.
You might assume that a full year is far longer than you need to work out if a mattress is right for you. And in some cases, it may be obvious far sooner than this that a mattress is just not cutting it.
But extra-long trial periods do have a couple of advantages:
Even putting length of trial aside, not all sleep trials are the same. Some come with a list of terms as long as your night-time snooze, while others are a dream to take advantage of. Conditions to watch out for can include:

The Premium Hybrid is the most popular Eve Sleep mattress on the Which? website for January. It's a one-sided mattress, so doesn't need to be flipped over. It's constructed from layers of different density foam, full-sized pocket springs, and memory foam.
Eve says this mattress is medium-firm in feel. In our independent firmness tests, it ranked as a four out of 10, where one is the firmest and 10 the softest. This puts it slightly towards the firmer end of the scale.

You may spot ads for this Nectar mattress doing the rounds on social media, especially as it's on sale at the moment. It's a memory foam mattress, made up of a large 16.3cm foam core, then 3cm of memory foam and 2cm of foam, all topped off with a quilted cover. The foam can make the mattress feel warm to sleep on, which may bother those who prefer a cooler-feeling surface to sleep on.
Nectar says this mattress is 'just about right' in terms of firmness. We say what's 'just about right' depends on your personal preference, which is why we independently test how firm each mattress is. In our firmness test, on a scale where one is the firmest and 10 the softest, we rated it a seven, so heading towards the softer end of the scale.

This Emma mattress continues to be the most popular mattress review on the Which? website, and it's often on offer. The Emma Original is made from a 19cm foam core, topped with two layers of foam of different thickness and density.
Unlike some foam mattresses, the Emma Original doesn't feel too warm to lie on, though you will feel the foam around you as you lay on the mattress - we call this the memory effect. This can be worse on some other mattresses, where you may feel like you're being enveloped in the mattress as you sink into the foam.
Emma says this is a medium firmness mattress. In our independent firmness tests, the Emma ranked as an eight on a scale where one is the firmest and 10 is the softest, so it may not feel as firm as you expect.
Is this the dream mattress for you? See what we uncovered in our full test review of the Emma Original mattress or buy it now from Emma.
