The best Sleep Number mattress sales in August 2025: save up to 50% on award-winning smart beds with these deals
If you're looking for an affordable smart bed online right now, there's 10% off the c2 smart mattress at Sleep Number, which means you'll pay $1,169.10 for a queen (was $1,299) and just $809.10 for a twin (was $899). Meanwhile, hot sleepers looking for an active cooling solution to help them sleep through the warmer months can enjoy up to $1,537 off the ClimateCool smart bed; a queen will cost you $4,674.15 (was $5,499).
On sale or not, we think the Sleep Number i8 is the best smart bed of the year when it comes to value for money. Even better, it's 25% off this August at Sleep Number, bringing a queen size to $2,999.25 (was $3,999).
These aren't the absolute best savings we've seen on these smart beds; for Memorial Day the i8 was $2,799.30 in a queen size, but the Labor Day mattress sales are only just starting to kick off, and we wouldn't be surprised to see prices drop by another $50-$100 or more in the week or two leading up to Labor Day itself. That said, you can also bag free delivery now if you act fast (fees usually start at $150).
But if you're desperate to upgrade to a smart bed built with cutting-edge tech that allows you to customize your sleep set up and keep track of you rest, here you'll find the best Sleep Number deals to shop now, plus everything you need to know about shopping at the brand, and you can find even more of today's best deals in our mattress sales round up.

What makes the iLE smart bed limited edition? Its upgraded temperature balancing, support and pressure relief, bringing pain-free sleep alongside nightly sleep tracking insights.

User score: ★★★★½ (37,250+ reviews)
2. Sleep Number i8 Smart Bed: twin was $3,399 now $2,549.25 at Sleep NumberThe Sleep Number i8 is a smart mattress that allows you to select your own firmness settings independent of the other side of the bed. This means unbeatable motion isolation (halt the sleep divorce) and customizable edge support. That said, our reviewer was hesitant to trust the i8's sleep tracking metrics, and she overheated on this mattress due to a lack of breathability. Still, if you think it's the smart bed for you, there's now a 25% discount that translates to a saving of $999.75 on a queen size, cutting the price to $2,999.25 from $3,999.

It sits between the Sleep Number c1 smart bed and c4 smart bed, and you can get a queen size for $1,169.10 now (was $1,299) after 10% off. We often see $200 off all sizes of this mattress, which is a better deal if you're shopping Cal king size or smaller. However, if you're after a split or FlexTop king or Cal king, now is the time to snap up the better saving.

You can get 25% off now, bringing a queen to $2,999.25 (was $3,999). That's a lot more expensive than even the best memory foam mattresses you can buy online, but a Sleep Number bed is not your standard bed. User score: ★★★★½ (7,430+ reviews)
Sleep Number's mattress suite consists of 12 smart beds, all lined with sleep tracking sensors and air chambers enabling you to adjust the precise feel of your bed while learning more about your overnight biometrics and how restorative your rest is.
The beds are split into five different mattress series, each with its own selling point. There's the affordable Classic series, the Performance series with enhanced pressure relief, the Innovation series offering better temperature balancing and the Memory Foam series. Plus the ClimateCool series introduces active cooling, and the Climate360 series bringing active cooling and warming.
The Classic series holds Sleep Number's entry-level beds including the c1 smart bed, c2 smart bed and c4 smart bed. These are 8" to 9" mattresses marketed towards sleepers looking to experience smart bed technology on a budget. Still, they are pretty smart and come complete with responsive air chambers that alter the feel of your bed as well as integrated sleep tracking, though you must make allowances for limited cooling power considering their price point.
Next is the Performance series, including models such as the p5 smart bed, p6 smart bed, and the newer pSE smart bed. In the wider market, these are positioned as a mid-to-upper-tier smart beds. Compared to the Classic series, they focus on enhanced comfort, cooling and pressure relief. These mattresses have thicker foam layers and targeted zoned support to cradle key areas like shoulders, hips, and knees.
Then comes the Innovation series which holds our recommended best value tech-loaded mattress of the year and Sleep Number's best-seller, the 12" i8 smart bed, alongside the 13" i10 smart bed and 12" iLE smart bed. These beds promise better temperature balancing thanks to additional ceramic gel that releases excess heat from the bed. However our reviewer found herself running hot on the i8 smart bed, so we suggest particularly hot sleepers shop the ClimateCool or Climate360, which come with reliable active temperature control.
Sleep Number Memory Foam is a one-model series with the 11" m7 smart bed. Though you can adjust the feel of any Sleep Number mattress, the m7 has more for those who enjoy extra cushioning around the joints. One reviewer says: "It feels like a cloud."
The Sleep Number ClimateCool smart bed is the one for year-round hot sleepers. Released in the fall of 2024, it's designed to banish night sweats with a dynamic airflow system that pulls heat away from your body while you sleep. This airflow system is complemented by a breathable cover and ceramic gel cooling layers. Sleepers can adjust the surface temperature to be up to 15 degrees cooler on either side of the bed.
The ClimateCool also introduces Sleep Number's SmartTemp Programs, developed in partnership with the Feinberg School of Medicine at Northwestern University. These presets are designed to promote deep sleep and ease temperature fluctuations due to hot flashes. Users can even create custom programs based on their preferences.
Finally, the Climate360 smart bed is the most sophisticated mattress from Sleep Number and arguably one of the most advanced options in the smart bed market as a whole (with a $10,000+ price tag to match at MSRP). But you do get adjustable positioning at the head and foot of the bed, meaning you can sleep in a zero gravity position to alleviate any back pain. Plus customizable firmness, sleep tracking and coaching and precise climate control that enables you to cool or warm each side of the bed by 15 degrees each way.
You can pair any mattress with a FlexFit base for an additional fee starting at $1,299 for a queen size. This enables you to fully customize the position of your bed along with its feel to reach ultimate comfort for your body. It also has Sleep Number's snore mitigation technology that adjusts your head position to open airways when snoring is detected, so you and your partner can get peaceful sleep.
The MSRP on Sleep Number mattresses tends to stay pretty consistent throughout the year, which can't be said for every mattress brand. The biggest sales rotate around the brand's mattress suite with the cheapest prices arriving near major holiday sales such as Black Friday and Labor Day. This is how much Sleep Number mattresses cost this month:

A Sleep Number mattress requires a firm, solid, and non-flexing bed base to properly support its adjustable air chambers and ensure optimal performance.
You can shop integrated bases and frames at Sleep Number as well as smart adjustable bed bases. The Sleep Number FlexFit adjustable bases are specifically designed to work with the mattress's technology and allows for heat and foot elevation, under-bed lighting and snore mitigation.
A platform bed with a solid surface (either no slats or very closely spaced slats no more than two inches apart) can also work. However it's recommended you avoid traditional box springs or foundations with wide slats or too much give, as they can interfere with the mattress's ability to maintain consistent support and may void the warranty.
Specializing in adjustable comfort, Sleep Number mattresses are ideal for couples who can't agree on mattress firmness levels, or those who struggle to find a mattress with the right balance of contouring and support for their body type and sleep position.
Also featuring in-bed tracking, they are well suited to tech-savvy sleepers curious about learning more about, and keeping track of, their sleep habits and biometrics.
With many options at affordable price points (we're looking at the Classic series) compared to other high-tech beds, Sleep Number mattresses are ideal for budget shoppers looking to test whether smart bed technology is right for them before making larger investments.
Overall, Sleep Number beds are worth their price tags and have great potential to elevate your sleep experience through customization options and sleep tracking.
A Sleep Number mattress is designed to last around seven to 10 years, though many owners report using theirs comfortably for even longer with proper care.
These mattresses are built with adjustable air chambers and durable materials, and they come with a 15-year limited warranty that covers manufacturing defects and certain component failures.
Longevity can vary depending on usage, maintenance, and the specific model, Expectedly, higher-end models with more advanced features may require more upkeep. Checking regularly for air leaks, keeping the mattress clean, and using the recommended base can help extend its lifespan.
Sleep Number mattresses come with a 100-night at-home sleep trial and can be returned through calling the brand's customer service center. However, you must keep the bed for at least 30 nights before returning it and you'll incur a $250 return or exchange fee, as per Sleep Number's return policy.
Don't forget Sleep Number charges a non-refundable delivery fee too, which we think is pretty harsh considering many other premium mattress brands (like Saatva) offer free White Glove delivery.

Saatva's been hiding a luxury memory foam mattress — here's how to find it and save $400
If you're set on buying a premium memory foam mattress, you may well have found yourself browsing the Saatva site to see what's for sale. And that's a wise decision; Saatva is the brand behind many of the best mattresses in the business, so it's always worth seeing what it has on offer. Here's a funny thing, though: look at the Saatva site and you'll see that the only all-foam bed on offer is the Saatva Contour5. And you know what? That would be a great buy: it's a luxurious option that ranks highly in our guide to the best memory foam mattresses. But hold on a second, because there's actually another luxury memory foam bed hidden away on the Saatva site, and it's well worth investigating if you're shopping the Labor Day mattress sales. It's called the Saatva Loom & Leaf, it sells for the exact same price as the Contour5 and it's made with similar materials, and if you follow our link you can get it with $400 off in an exclusive Labor Day offer. So what's the deal with the Loom & Leaf, and is it worth shopping in the mattress sales? Here's what you need to know, Saatva Loom & Leaf: twin was $1,899 now $1,499 at SaatvaThe Saatva Loom & Leaf is a luxury mattress made with premium 5lb memory foam that provides plenty of contouring and pressure relief, along with outstanding motion isolation. And it offers enhanced lumbar support, making it a strong choice if you're looking for a mattress that can help with back pain. As an all-foam bed, however, it's prone to trapping heat, and although it comes in two firmness options it may still be too plush for some. Follow our link to get $400 off the Loom & Leaf in the Saatva mattress sales; a queen is reduced to $2,599 (was $2,999) and you'll get free white glove delivery, a 365-night home trial and a lifetime warranty. Returns will cost $99, though. The Saatva Loom & Leaf is a premium 12" memory foam bed, made with body-hugging 5lb memory foam. First sold by Saatva back in 2015, it comes in two firmness options: there's a relaxed firm model that Saatva rates a 5-7 out of 10, and a firm option rated 8 out 10, so there's an option for every sleep position. Beneath the Loom & Leaf's quilted top cover there are five layers of foam that combine to provide lower back support and breathability, while delivering just the right amount of all-body support. In our Saatva Loom & Leaf mattress review our lead reviewer was impressed by how this mattress helped with her lower back injury and noted how after three weeks sleeping on it she was waking up with almost no lower back pain. She was impressed by how the Loom & Leaf's dense foam almost eliminated motion transfer, however she did find that it was lacking in edge support and, more importantly, that despite cooling tech built into several of its layers, it had a definite tendency to trap heat. In general, however, she recommended it for anyone suffering from a sore back or joint pain, and loved the cushioned support it delivered, along with its build quality. So, why has Saatva hidden the Loom & Leaf away on its site? I have a couple of thoughts on that. The first is the Saatva Contour5. While it's not exactly the same mattress as the Loom & Leaf, it's very similar and comes in at the same price in all sizes. And as you'll learn from our Saatva Contour5 mattress review, it's much better than the Loom & Leaf at keeping cool, thanks to features like a CoolVent system that wicks away heat and gel-infused foam that also air flow channels throughout. Saatva Contour5: twin was $1,899 now $1,499 at SaatvaThe Contour5 supports all sleep positions and delivers plenty of pressure relief and minimal motion isolation. It comes in medium and firm feels, and it's an improvement on the venerable Loom & Leaf when it comes to cooling prowess. Use our exclusive Saatva link and you can get $400 off the Contour5 in all sizes, which means a queen will cost you $2,599 (was $2,999). That's a great price for one of the best and most luxurious all-foam beds on the market. Why not just ditch the Loom & Leaf then? Well, as I mentioned, it was launched back in 2015, and if you read its user reviews, you'll see that it's a well-loved mattress with some customers coming back to buy another when their old one needs replacing. So why wouldn't Saatva keep the Loom & Leaf available for returning customers? It makes its mattresses to order, so it's not a big deal to keep turning out the odd Loom & Leaf when requested, even if its memory foam focus is on the Contour5. Personally, I think the Loom & Leaf looks much nicer than the Contour 5, thanks to its quilted top and handles, even if its cooling isn't quite as good. But whichever option you choose I think you'll end up with a quality memory foam mattress.

Otherwise, it packs the same 128GB of storage, 12MP rear camera, WiFi 6E support, and a 12MP front camera. The new CPU and larger display should make this iPad a favorite for gamers.
