Editor's choice: Today's 5 best mattress sales
Learn how we pick our best mattress sales ▼
Here at Tom's Guide, we test mattresses for hundreds of hours, using a mixture of qualitative and quantitative data to build an unbiased view of each model. We also track mattress sales throughout the year, so we know which deals are good and which ones aren't worth your time.
The picks in our Editor's Choice category represent the deals we know are good value on mattresses we recommend.
Memory Foam mattress deals
Learn more about memory foam mattresses ▼
Memory foam mattresses are made of multiple layers of dense cushioning. We often recommend them for aching joints, as the foams 'hug' the body to relieve pressure where you press into the mattress.
All-foam mattresses are also good for bed sharers, eating up movement so your partner's restless night doesn't disturb you. But despite a reputation for softness, memory foam mattresses encompass a range of feels — like the ultra-firm all-foam Plank mattress.
In fact, our expert-tested best memory foam mattresses guide has an all-foam mattress for every sleep style.
Hybrid mattress deals

Hybrid mattresses combine body-hugging foams with supportive innerspring layers to bring you the best of both worlds. No mattress is one-size-fits-all but if you're not sure where to start, a medium-firm hybrid mattress is typically a crowd-pleaser.
Spring-based hybrid mattresses have their pros and cons — the bouncier feel can disrupt couples but the open design aids air flow — but our favorite hybrid mattresses offer exceptional support across the board.
Latex mattress deals

Latex mattresses are becoming increasingly popular, due to their eco-friendly credentials. Latex foams have bouncy, buoyant pressure relief and natural breathability, and although the best organic mattresses can be premium picks, they're also known for their durability.

Mattress sales FAQs
What is the best month to buy a new mattress?
The best month to buy a mattress is typically November, when the Black Friday sales are in full swing and you can expect a discounts from nearly all our favorite mattress brands and retailers. December is also a good month to buy a mattress, as the Black Friday and Cyber Monday sales often bring discounts at the start of the month.
Black Friday used to be the time of year to get a mattress for less, with discounts to beat all the other deals. However, in recent years we've seen that shift and now while Black Friday is still one of the biggest mattress sales, it has competition.
May is another great month to buy a mattress as the Memorial Day deals are often comparable to the Black Friday discounts.
Other good months to shop are President's Day (in February) and Labour Day (in September.)
There's no month in which you won't find a mattress sale (really, there's always one somewhere) but summer does tend to be quiet in terms of deals. But if there's a summer mattress sale worth browsing, our deals experts will have found it and we'll be tracking it here.
How to get the best mattress deal
To get the best mattress deal for you, the first thing to do is decide what you need from a mattress. Soft cushioning? Firm support? A cooler sleep feel? Deciding the kind of mattress you want before you start shopping prevents you from losing money on a bed that doesn't suit your needs.
When shopping for a good mattress deal, pay attention to the final price, not how big the discount is. There are many mattresses never sold at full price so although that huge saving looks promising, it might be distracting you from a final price you don't want to pay.
If you can, save your shopping for the peak sales days, such as Black Friday, President's Day, Memorial Day and Labor Day. This is when we see the widest scope of discounts, meaning you have plenty of options to choose from.
And don't ignore freebies. Many brands offer a free pillow or bedding with a mattress, saving you another purchase down the line.
Although on the flip-side, sometimes it's better to leave the freebie and opt for a mattress with a bigger percentage sale... particularly if you already have the best pillow for you.
Have a look on third-party sites, particularly if you're shopping for a budget mattress. Retailers such as Amazon and Walmart often have big discounts on cheap beds.
But don't forget the benefits. A sleep trial is important to avoid a costly mistake when buying a bed online and we think it's typically worth paying extra for a bed with a trial over sacrificing the trial for a saving — and getting stuck with a bad mattress.
Mattress deals — tips to remember
- Shop the peak sales: Labor Day, Black Friday/Cyber Monday, Memorial Day, and July 4th are generally the best time of the year for mattress deals. Black Friday used to stand out as the top mattress sale day by a long shot but lately Memorial Day has been catching up (and even Presidents' Day and Labor Day sales have been promising.)
- Look out for evergreen sales: Some of our favorite sleep brands — including Nectar and DreamCloud — run sales throughout the year and you rarely risk missing a better price by shopping these deals. In this guide, we've highlighted which sales are evergreen and which are new, wherever possible.
- Know your return policy: Buying a new mattress can be tricky, as everyone's sleep needs are unique. Most online mattress brands offer a sleep trial — time to test the bed at home — with returns for free (or a minimal fee) within this period. Some brands, particularly budget beds and third-party retailers, only offer returns if the mattress is in the original condition. In other words, still rolled up in its box.
- Don't skip the sleep trial: Okay, this is practically the same point as above but the sleep trial is our number one piece of advice when buying a mattress online. A standard trial lasts 100 nights but some brands offer up to a full year — well over the estimated 30 nights it takes to adjust to a bed. With a sleep trial, you can test the bed where it mattress most: in your own bedroom.
- Save with Medicare: If you're in the US and buying a mattress to help with a medical condition such as chronic back pain, you may be eligible for Medicare support. For all the facts you need to know, see our article on what types of mattresses are covered by Medicare.
Finding the best mattress coupons
Like many retailers, mattress manufacturers occasionally offer discounts via coupon codes. Some brands are upfront about their promo codes and list them on their respective websites. Others have the tendency to hide them. Make sure to check out our guide to the best coupons via our guides: Nectar promo codes, Tempur Pedic promo codes, Purple promo codes, Casper promo codes, DreamCloud coupons, and Awara promo codes.
