Sleep Number has launched its Labor Day sale early and with up to 25% off smart mattresses and bases, it’s one of the biggest sales of the year. That includes a saving of over $999 off a queen size ComfortNext Lux mattress, the most popular adjustable bed in the line-up.
Sleep Number beds are made different. Most of the best mattresses we’ve tested use springs and foams to create consistent comfort. These high-tech beds are fitted with adjustable air pockets that can be made softer or firmer, depending on your comfort needs. We think they’re among the best smart beds you can buy online.
It’s been a year of ups and downs at Sleep Number but this mattress sale is an up for anyone looking to invest in a smart bed. Here’s everything you need to know…
Top deals in the Sleep Number mattress sale this month
Which Sleep Number mattress should you choose?
Sleep Number's mattress suite is divided into three collections: the entry-level ComfortMode beds, the flagship ComfortNext, and the cooling Climate series. All beds come with Sleep Number's famous adjustable firmness.
The ComfortMode collection beds are for those who want adjustable comfort without the bells and whistles. Remote controlled (no app required), the air chambers allow you to make the mattress softer or firmer. There are no smart features but the responsive air tech means the feel changes as you move in the night. Upgrade to the ComfortMode Lux for more cushioning and cooling features.
The ComfortNext collection is the flagship series. The adjustable comfort is still at the heart of the mattress, but these beds are also fitted with sleep trackers. Accessed via the SleepIQ app, the trackers monitor your sleep during the night and deliver insights the next morning.
In addition, the ComfortNext collection features air chambers, foam and springs, for more targeted support. Upgrading to the ComfortNext Lux or Ultra gets you more cushioning and better cooling.
Speaking of cooling: the Climate beds are the only in the Sleep Number collection to feature active cooling (alongside adjustable firmness, of course). The Climate mattress can cool by up to 15°F, while the Climate 360 can adjust 30°F warmer to cooler. These are also the most expensive beds from Sleep Number, but both come with foundations included in the price.
How much does a Sleep Number mattress cost?
Sleep Number mattresses are premium beds; they're priced comparatively to the best luxury mattresses. But instead of indulgent finishes and premium materials, these beds are packed with the latest sleep tech.
Sleep Number sales happen regularly but the deals tend to move between mattresses. So if the bed you want isn't on sale right now, it might be discounted in a few weeks, when the offer changes.
While these sales are frequent, Sleep Number tends to reserve the biggest discounts for major holidays. Think Memorial Day, Labor Day and Black Friday.

Sleep Number mattress sales FAQ
What bed base do I need for a Sleep Number mattress?
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.
Are Sleep Number mattresses worth it?
Specializing in adjustable comfort, Sleep Number mattresses are ideal for couples who can't agree on a mattress firmness level. They're also suited to those who struggle to find a mattress with the right balance of contouring and support for their body type and sleep position.
Sleep Number beds can also appeal to those with reoccurring or chronic aches and pains. The changeable firmness allows you to adjust the mattress to your needs, even if your preferences change every night.
For the tech-savvy, the ComfortNext collection features integrated sleep tracking. This can help you get to grips with your sleep problems, as you can pair different comfort levels to your sleep quality that night. But for those who prefer to keep tech out of the bedroom, the ComfortMode beds deliver app-free comfort.
Smart beds are still a premium market so while Sleep Number beds are expensive, they're priced competitively. If it's adjustable comfort you're after, then we think Sleep Number is worth the money.
How many years should a Sleep Number bed last?
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.
How hard is it to return a Sleep Number bed?
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.
