Your new mattress should make going to bed the best part of your day. If you're not happy with your purchase, simply swap it - no questions asked. Just a heads up, there is a one-off £99 fee to cover the collection of your old mattress and delivery of your new one. But don't worry, our team are here to make it as smooth as possible.
Sleep Trial
Your dreamy sleep trial starts now
We offer a 100 night sleep trial on selected mattresses. If you’re not satisfied with your mattress, you can simply swap it for another within your trial period.
MattressNextDay offers a 100 night sleep trial. If customers are not satisfied with their new mattress, they can swap it within the trial period.


We think you’ll love your new mattress because thousands of other sleepers already love theirs. However, if after your sleep trial starts, you’re not completely satisfied with your purchase, just let us know that you’d like to invoke a sleep trial exchange (be sure to do so before the sleep trial ends). You can do this by emailing our friendly sleep team at sleeptrial@mattressnextday.co.uk
You've got a whopping 750* hours of snoozing to figure out if you're head over heels for your new mattress. That's the same amount of time it takes to learn a new language, so there's plenty of time to make a decision. Bear in mind, you'll need to sleep on it for at least 50 nights.
*Based on an average of 7.5 hours sleep over 100 nightsSleep trials are available only on mattresses with sleep trial information & badge on their product pages.
Your sleep trial begins when the mattress arrives at your door.
Yes, it is. The sleep trial itself doesn't cost anything. If you decide to exchange the mattress after 50 nights, there will be a one-time £99 fee for collection and delivery of the new one.
Your new mattress will be delivered at the same time we collect your old mattress.
We encourage you to sleep on it for at least 50 nights; this is how long it can take to get used to the mattress. We can't accept Sleep Trial exchanges before then.
