Amazon Prime Big Deal Days is almost over, but there's still some time to save on mattresses. In some cases, the best Prime Day mattress deals are not actually on Amazon but are direct on a mattress retailer's website. We've included these sales and more in this article.
Many of our best mattress guide picks are on sale, including the top overall mattress, the Leesa Sapira Hybrid. This bed has a balance of firmness and support that will appeal to most sleepers, and it's $400 off. If you're on a tight budget, consider the plush, cooling Siena Memory Foam Mattress, marked down to $339.15.
We've continuously updated this article with the latest deals throughout the event, so the sales below are still relevant even in the final hours of Prime Day. If you're looking for sales in other categories, like bedding, vacuums, or TVs, check out our main Prime Day deals hub.

The medium-firm Helix Dusk Luxe is tailor-made for back and stomach sleepers. The hybrid sleeps exceptionally cool and provides excellent support, but edge support was lacking.

The DreamCloud Premier Hybrid Mattress performed well in all of our tests, which makes it ideal for most sleeping types, couples, and people who tend to overheat at night.
The best Amazon Prime Day memory foam mattress deals
The best foam mattresses contour to your body for unparalleled spinal alignment and pressure point relief. I'm sleeping on the newly revamped Nectar Memory Foam Mattress. I'm impressed with its support and comfort. It's marked down to $551.65, an all-time low price.
The gel memory foam of the Nectar makes it a versatile mattress that conforms to the contours of your body to relieve pressure. It's a premium sleep experience, but its price tag is way under a grand.

The Lucid 8-Inch Gel Memory Foam Mattress is made from two layers of foam — a gel-infused, ventilated foam for breathability and a high-density foam for better support.
This Signature Design by Ashley memory foam mattress has a 12-inch plush core that molds to whatever position the body lays in.
The softer-than-average firmness of the Siena Memory Foam Mattress makes it the ideal choice for side sleepers, especially those who overheat.

The memory foam of the Bear mattress, combined with Celliant technology, makes this a great bed for active folks looking for some rest and recovery.
Couples shopping for a foam mattress will appreciate the GhostBed Luxe Mattress's medium firmness, great motion isolation, and excellent edge support.

The best Amazon Prime Day latex mattress deals
Latex is an eco-friendly material that improves a mattress's responsiveness to your body's weight, reducing aches and pains. The Birch Natural by Helix is the best organic mattress I've tested. It's about $470 off and comes with two free pillows.
Thanks to its all-natural materials, the Birch Mattress is guilt-free for environmentally conscious folks.

Popularized by Sleep Number, adjustable airbeds are pricy, but you can adjust the firmness on each side of the bed so you and your partner can achieve a custom feel. The Sleep Number i8 is the best adjustable bed we've tested, and it's $600 off right now.
If you and your partner just can't agree on mattress firmness, the Sleep Number i8 Smart Bed allows you to customize each side to your perfect firmness. The bed automatically adjusts based on your body's position.
The pricey Sleep Number Climate360 Smart Bed is all about customization, with firmness, temperature, and incline adjustments.

Is Prime Day a good time to buy a mattress?
Yes. Brands tend to mark down their mattresses regularly during holiday weekends, like Black Friday, Cyber Monday, and Presidents Day. Yet, Prime Day also attracts deep discounts. Many deals are on Amazon, but in recent years, manufacturers have begun offering rival sales on their own websites.
Are other bedding items on sale?
Pillows, sheets, and blankets are among the many bedding items on sale for Prime Day. You can find a full breakdown of the best Prime Day bedding deals in our guide. Some of our favorite pillows are currently on sale if you're looking to completely revamp your bedroom space after you buy a new mattress.
