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 summer and fall. 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 in June 2026.
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, Nectar 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 summer and fall. 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.
