May has officially arrived, which means the 2021 Memorial Day mattress sale event will be here before you know it. To help you find all the top offers, we’ve created this guide with the best mattress deals you can buy right now and the top Memorial Day mattress sales that should be launching in the coming weeks.

The Memorial Day sales event is a perfect opportunity to score your dream mattress at a discounted price from top brands like Purple, Nectar, Saatva, TempurPedic, and more. Whether you want to save money on the best mattress you can buy, or you’re looking for the cheapest (quality) mattress possible, we’ll have you covered. 

May is one of the best times of year to buy a new mattress online. Spring is traditionally when mattress brands release their new stock, and plenty of companies use their Memorial Day mattress sale as an opportunity both to promote new lines – with sitewide offers and free accessories added to your order – as well as to dramatically discount last year’s models.

Deal quality is high: we see some of the biggest offers of the year in the Memorial Day mattress sales. The offers are generally as big as those on Black Friday, so it’s a very, very good time to buy a new mattress. (If you’ve never bought a mattress online, it’s easy – we’ve shared some pro tips at the bottom of the page.)

That said, if you can’t wait for Memorial Day and need to buy a new mattress right now, there are lots of excellent sales happening already. We’ve rounded up the best deals here…

5 pro tips for buying a mattress online

If you’ve never bought a mattress online, it’s probably easier than you think, and it’s likely cheaper too – many brands have been able to lower the cost of their mattresses by choosing not to have physical stores, and passing those savings onto customers. Here are five things to look for when buying a mattress online. 

1. Choose a mattress that has at least a 60-night trial
Most top brands now let you test a mattress properly by sleeping on it at home. This is a much more effective way to decide whether a mattress is right for you than spending five minutes with it in a showroom. If you decide the one you’ve chosen isn’t right within the trial period (and it isn’t badly damaged), you’ll get a refund and it’ll be collected. 

We’ve made sure all the mattresses in our Memorial Day mattress sale round-up come with at least a 60-night trial – the majority come with 100-nights, and some, such as Nectar, give you an entire year to decide whether you like it.

2. Check for free returns
As part of the risk-free trial, most brands offer a full refund and free returns if you decide the mattress isn’t right for you. However, some do charge a fee for collection, around $75, so check the policy first.  

3. Read third-party T&Cs
We usually recommend buying your mattress directly from the manufacturer so that you can make the most of generous sleep trial and warranties. You’re more likely to get a better deal from the manufacturer too, with competitive discounts and free gifts often added to your order. 

However, sometimes a third-party retailer can run a deal that makes it slightly cheaper than buying through the manufacturer. If you’re looking for the cheapest price possible, this can be a good way to get it – however bear in mind that you may not receive the same trial or warranty benefits if you buy from a retailer such as Amazon, so always read the T&Cs carefully first.

4. Make sure it’s the right size
Do the elbow test to work out what size mattress you need. Lie back with your hands behind your head. If you share a bed, your elbows should be able to extend without touching your side of the bed or your partner’s elbow; if you don’t share a bed, your elbows should be able to extend without touch either side of the bed.

5. Give a new mattress three weeks
It can take up to three weeks for your body to adjust to a new mattress. So even if it isn’t comfortable initially and you wake up with aches and pains, stick with it – particularly if your body is used to sleeping on a much older mattress. If after three weeks you still don’t like it, then you know it’s because it isn’t right – rather than because your body still hasn’t readjusted from sleeping on a less supportive or different mattress.
