The Amazon mattress sales are always worth checking out if you're in search of a decent mattress at the lowest possible price, and if you're heading back to college and want to upgrade a nasty dorm room bed, now's a great time to shop. Right now you can get up to 25% off the Siena 10" Gel Memory Foam Mattress at Amazon, with a twin reduced to $149 from $199, and a queen down to $279 (was $349); that's less than you'll pay at Siena.

We wouldn't necessarily recommend Amazon if you're shopping for one of this year's best mattresses, simply because you'll do better in terms of sleep trial and warranty when you buy direct. But if price is your priority it can be a winner, particularly if you pick your moment to buy.

You've just missed a whole load of excellent Prime Day deals, but there are still some strong mattress sales to be found at Amazon (and you won't need a Prime subscription to make the most of them). We've picked out the three best mattress deals available right now, as well as three great discounts on mattress toppers — ideal if you want to improve the feel of a dorm bed without replacing the entire mattress.

Amazon mattress sales: Our top 3 deals

1. Siena 10" Gel Memory Foam Mattress (twin):was $199now $149 at Amazon

1. Siena 10" Gel Memory Foam Mattress (twin): was $199 now $149 at Amazon
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. There's up to 25% off at Amazon right now, with a queen reduced to $279, 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, making this one of the best Amazon mattresses you can buy.

2. EGOHOME 12" Black Memory Foam Mattress:was $429.99now $329.99 at Amazon

2. EGOHOME 12" Black Memory Foam Mattress: queen was $429.99 now $329.99 at Amazon
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-round support for both back and side sleepers, and great edge support and motion isolation. You need to pick your time to buy on Amazon, though, as discounts can vary according to size. Right now the only saving is on the queen size, and while at £329.99 it's a little more expensive than it was on Prime Day, at least this deal is available to everyone.

3. Tuft & Needle Kin 10" Mattress (twin):was $449now $362.81 at Amazon

3. Tuft & Needle Kin 10" Mattress (twin): was $449 now $362.81 at Amazon
Tuft & Needle's Kin mattress range is Amazon-exclusive and features T&N's adaptive foam, only without graphite and cooling gel, at a low price. This 10" hybrid mattress-in-a-box has a medium-plush feel and features a layer of individually wrapped coils to add bounce and breathability, making it a good choice if you tend to sleep hot. There's 23% off a queen size, taking the price down to $614.74 (was $799); you'll get a 100-night trial and a 10-year warranty.

Amazon mattress topper sales: Our top 3 deals

1. Serta ThermaGel 3" Cooling Topper: was $74.99 now $59 at Amazon

1. Serta ThermaGel 3" Cooling Topper: twin XL was $74.99 now $59 at Amazon
If you're looking for a mattress topper to spruce up a standard dorm bed, a twin XL is the size to look for and this cooling 3" memory foam topper from Serta is a fine choice at a great price. All sizes except the twin are reduced right now, with the biggest saving on the king size, but at just $59 the twin XL is a back-to-school no-brainer, while a queen will set you back just $75.92 (was $94.99).

2. Sealy Dreamlife 2" Gel Memory Foam Mattress Topper (twin): was $79now $63.26 at Amazon

2. Sealy Dreamlife 2" Gel Memory Foam Mattress Topper (twin): was $79 now $63.26 at Amazon
This slimline topper from Sealy is made with cushioning gel memory foam to add tailored pressure relief and support to any bed, and it comes in at a very reasonable price. There are discounts on most sizes at Amazon right now, and if you need queen size you'll find that it has 37% off taking the price down from $129 to just $81.47. It comes with a one-year warranty, too.

3. Elemuse Dual Layer 3" Memory Foam Mattress Topper: was $119.99now $89.99 at Amazon

3. Elemuse Dual Layer 3" Memory Foam Mattress Topper: twin was $119.99 now $89.99 at Amazon
For a plush comfort boost that won't break the bank, this dual-layer topper from Elemuse is worth investigating. It combines two inches of gel memory foam with a 1" top layer of breathable down alternative fiber, delivering plenty of comfort and pressure relief where you need it. Most sizes are discounted at Amazon right now; sadly the dorm-ready twin XL only has 7% off, dropping the price to $139.99, but a queen has a 27% saving that brings the price down to $109.96 (was $149.99).

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 check CamelCamelCamel for price drops and sale history if you're only concerned about bringing home a new mattress at the absolute lowest price.

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.
