Amazon mattress sales are always my go-to when looking for mattress deals. You're often guaranteed to find a great deal on a mattress we love, like the Siena Signature that's down to $244 for a queen at Amazon.

With Black Friday and Cyber Monday sales winding down, we are looking forward to the next big shopping event for even more sales.

Amazon mattress sales: Our top 5 deals

Siena Memory Foam Mattress (twin)
Save $40
Siena Memory Foam Mattress (twin): was $199 now $159 at Amazon
Read moreRead less

1. We rate the Siena 10" Memory Foam Mattress as the best budget mattress you can buy, and Amazon is the place to buy it if you want the lowest price. It has a firm feel that makes it best suited to back and stomach sleepers, it delivers outstanding edge support as well as low motion transfer, and for a memory foam bed, it's surprisingly good at temperature regulation. For Prime members, the Siena is now $244 for a queen on Amazon, which is a lot less than the $359 you'd pay at Siena, and you'll get the same 180-night trial and 10-year warranty. This is one of the best Amazon mattresses you can buy.

EGOHOME 12" Black Memory Foam Mattress (twin)
Save $42.01
EGOHOME 12" Black Memory Foam Mattress (twin): was $279.99 now $237.98 at Amazon

2. We were surprised by how well this budget bed performed in our EGOHOME Black 12" Memory Foam Mattress review, and we think it's one of the best mattresses on Amazon under $400 for a queen. What it lacks in cushioning, it makes up for in all-around support for both back and side sleepers, and great edge support and motion isolation. Right now, the queen size is down to $280.49, which is cheaper than direct from EGOHOME. However, if you do shop on EGOHOME, you will get a sleep trial, so think carefully about what you need.

Cool Gel Memory Foam Mattress (twin)
Cool Gel Memory Foam Mattress (twin): was $248.51 now $204 at Amazon
Read moreRead less

3. This memory foam mattress is designed to offer pressure relief and promote spinal alignment. It has an open-cell structure, which may prevent overheating — cheap memory foam mattresses can sleep hot but we have high hopes for this bed's cooling prowess. The Cool Gel mattress is CertiPUR-US certified and made from eco-friendly materials. Right now, a twin is $204, and that's the only size there's a discount on.

User score: ★★★★½ (57,360 reviews)

Lucid Memory Foam Mattress (twin XL)
Save $15.49
Lucid Memory Foam Mattress (twin XL): was $249.99 now $234.50 at Amazon
Read moreRead less

4. We rarely see sales on Lucid mattresses, so we definitely had to include this one in our roundup. Right now, a twin XL is $234.69 (was $249.99) and a full is just $283.15 (was $309.99). This memory foam mattress is made to offer comfort and pressure relief. You can also choose what type of firmness you'd like, from plush to medium-firm. A plush mattress would better suit side-sleepers, while firm mattresses are geared for stomach sleepers or those with back pain.

Amazon mattress sales: Expert analysis

When it comes to mattress sales, major holidays usually offer the cheapest prices. These include Memorial Day mattress sales, Labor Day mattress sales and Black Friday mattress deals. However, Amazon hosts its Prime Day event twice a year, usually in July and October. Although mattresses aren't a huge focus of these sales, we did spot some great sleep deals during the last Amazon Prime Day mattress sale.

Amazon also tends to sell older models of mattresses from major brands, which of course, will yield big discounts. We've spotted all-time price lows on discontinued mattresses from Nectar and Casper during Amazon mattress sales. Casper and Tuft & Needle also produce mattresses that are exclusively sold at Amazon — usually at a discount.

Occasionally, you can find mattresses cheaper at Amazon than directly through the retailer. This is often for older models, but occasionally Amazon will sell a current model for less, as well. Brands we've seen undercut by Amazon include Zinus and DreamCloud.

It's worth paying close attention to the benefits you'll receive when buying a mattress through Amazon, as it may require you to abide by Amazon's standard return policy (100 days). Contact Amazon or the manufacturer to understand just what you'll be getting with your purchase.

Amazon mattress sales: FAQs

Does Amazon have the cheapest mattress prices?

That depends on which mattress you're looking at. You'll typically find mattresses for their cheapest prices on the brand's own website. This is different from most consumer products, which you'll generally find cheaper at Amazon.

Amazon's biggest discounts come during major sales periods like Presidents' Day, Memorial Day, Labor Day, and Black Friday — as well as its twice-yearly Prime Day events in July and October. This is when you're likely to find major name-brand mattresses from the likes of Nectar, DreamCloud, and Sealy available for less at Amazon than directly from the manufacturer.

Of course, Amazon offers discounts every single day of the year, and it can be hard to predict when these deals will land, let alone how substantial the markdowns will be. Many of these discounts will be on cheaper mattresses including Amazon's own Amazon Basics range and lesser-known brands like Novilla and Napqueen.

How to spot a good Amazon mattress deal

While Amazon's best deals will come during major sales events, the infrequent discounts that occur between these periods are difficult to predict.

One way to spot a legit mattress deal on Amazon is simply to check the prices elsewhere against what Amazon offers. Your first port of call should be to go directly to the manufacturer to find out if they offer a better price and/or extras and benefits with your purchase.

Beyond that you can always bookmark this page. We'll be updating it each month with the best Amazon mattress and sleep deals.

Can you return a mattress to Amazon?

Check the product page for most mattresses sold at Amazon and you'll see that the return policy is 100 days; however, a closer look at the Amazon Return Policy shows that it's 90 days.

We recommend reaching out to Amazon and confirming what benefits come with your mattress, as there may be a chance the manufacturer's trial period will be honored instead. For more detailed guidance read our feature on how to return a mattress to Amazon.
