3 best options we tried for you
Can I Use Regular Sheets on A Sleep Number Mattresses?
Yes, you can use regular sheets on your Sleep Number Bed without any problems. You have the option of buying those sheets from the brand. But if you want to save some money, you can leave the sheets from the brand and use the ones you already own.
Most people think that you need special sheets on Sleep Number beds because they have a difficult time keeping their sheets on these beds. But there are different ways to keep these bed sheets on the bed.
For instance, you can use bed sheet suspenders, elastic bands, and deep pocket sheets. If you add these features to your bed sheets, you will be able to keep your bed sheets on your Sleep Number bed for a long time.
Who Might Like Sleep Number's True Temp Sheets?
Sleep Number has True Temp sheets that you have the option to purchase with your Sleep Number bed. These bed sheets are equipped with the company's 37.5 technology.
With the help of this technology, your sleep surface will continue to adapt according to your body temperature throughout the night. So it is an excellent option for any dreamer to tend to sleep hot.
These bed sheets will automatically regulate your body temperature and keep you comfortable at night. As a result, you can enjoy a good night's sleep (also check 10 best-selling sheets for winter).
Also, these bed sheets also come with a 30-night trial. It means that you can comfortably use them for a month and test out whether they work for you or not. And if they don't work well, you can always send them back.
Who Might Not Like Sleep Number's True Temp Sheets?
These bed sheets might work well with your Sleep Number bed. But they are certainly not the best option to choose if you don't sleep hot.
Because the technology used in developing these sheets pairs well with the technology used in the construction of the Sleep Number mattress. And it will keep you cool throughout the night.
But this combination is not the best if you don't sleep hot or live in a colder climate. But most of the negative reviews come due to the overall durability of these True Temp sheets. So these are certainly not the sheets that will outlast the apocalypse.
Also, 300 thread count sateen weave sheets are entirely made of cotton, so they don't feel that soft even though they are highly breathable. These are some things you need to keep in mind before buying these True Temp sheets by Sleep Number.
What Do the Sleep Number's True Temp Flat Sheet Feel Like?
As with most Sleep Number products, these sheets tend to feel lofty and breezy. They will never feel very heavy on your body. The sheet is made of cotton percale, and it feels mild and cool and is not excessively sticky, and you won't have to deal with that slimy sensation.
They are pretty comfortable for hot sleepers because they can regulate temperature and feel highly breathable. Still, we would say that these sheets are a bit too cold to use in winter or if you live in a colder climate or tend to sleep hot.
Sleep Number's True Temp Sheets Materials
The True Temp sheets by Sleep Number are made of cotton percale. It's reminiscent of that Mediterranean beachfront and feels breathable and crisp. The cooling features of these sheets vary by model, design, and color.
Also, you will find a polyester blend to ensure that exquisite premium feel. It provides you with that premium down feeling, so if you tend to sleep cool, this variety will work better for you. So whether you sleep hot or sleep cold, it is up to you to choose the right type of blend that meets your requirements.
What to Consider Before Buying Sleep Number Sheets?
There are various aspects that you need to consider before buying these Sleep Number sheets. We are listing the down below for your assistance,
Material and feel
The most crucial factor you must consider before buying these Sleep Number sheets is materials. You will have to decide the materials based on whether you sleep hot or cold.
If you tend to sleep hot, the best option for you to go is cotton, as it will keep you nice and relaxed during your bedtime. And if you sleep cold, you should go for a sheet that has polyester in it as it will give you that down feeling for a most comfortable rest.
Size and specs
Size is always an integral point because you don't want your sheets to pile up when you move around on your bed if it's too long or short.
It feels pretty frustrating when you get up in the middle of the night to fix your sheet to keep lying in a pile. It can also disrupt the sheet's overall breathability and jeopardize the temperature regulation's purpose entirely.
Sleep Number's policies
You also have to keep in mind the policies that the brand has to offer to its customers. For instance, you need to check whether you have to pay for the shipping and returns or not. Sleep Number offers free-of-cost shipping and return to provide you with true peace of mind.
The company also offers a 30-day trial period to test out the sheets and decide whether they are suitable for you or not. But you have to remember that their refund policy is not that simple after 30 days.
Also, these True Temp sheets come with a 1-year warranty which is a blessing. Unfortunately, most cheap online retailers don't offer any warranty on these bedding accessories.
But as Sleep Number is a high-end brand, you will get the option to enjoy this perk and submit your claim in case of any discomfort.
Key Takeaways: Sheets for Sleep Number Beds
Compatibility of Regular Sheets with Sleep Number Beds
Sleep Number beds are known for their quality and customization, but a common misconception is that they require special sheets. The truth is, you can comfortably use regular sheets on your Sleep Number bed. If the sheets you currently own fit well, there's no need to purchase additional sheets from the brand, which is a relief considering the investment already made in the Sleep Number bedding. To tackle the common issue of sheets slipping off, consider using bed sheet suspenders or elastic bands to keep the sheets in place.
Exploring Sleep Number's True Temp Sheets
Sleep Number offers True Temp sheets equipped with new 37.5 technology, designed to adapt to your body temperature throughout the night. This feature is particularly beneficial for individuals who tend to sleep hot, as it aids in maintaining a comfortable sleep surface by regulating body temperature. The sheets come with a 30-night trial, offering a risk-free opportunity to determine their suitability for your sleeping preferences. However, if you don't sleep hot or reside in a colder climate, these sheets may not be the optimal choice, as some users have pointed out durability concerns and a lack of softness due to the 300 thread count sateen weave made entirely of cotton.
Feel and Materials of Sleep Number's True Temp Sheets
Sleep Number's True Temp sheets, crafted from cotton percale, provide a breathable, crisp feel reminiscent of a Mediterranean beachfront. They offer a cooling effect, making them suitable for hot sleepers. For those who sleep cool, a variant with a polyester blend might be a more comfortable choice, providing a premium down feel to keep you warm and cozy.
Key Considerations Before Purchasing Sleep Number Sheets
Before investing in Sleep Number sheets, it's prudent to consider the material based on your temperature preferences during sleep. Cotton is ideal for hot sleepers due to its cooling properties, while a polyester blend is suited for those who sleep cool. Size is another critical factor to ensure the sheets don't bunch up during movement. Lastly, familiarize yourself with Sleep Number's policies, including the 30-day trial and 1-year warranty, to ensure a hassle-free purchase and the ability to test the sheets' suitability for your comfort needs.
Conclusion
Sleep Number is truly a quality brand that stands behind its products, including the bedding accessories. That is exactly why these accessories come with a 30-night trial and a 1-year warranty.
These sheets are pretty good at regulating temperature and make you feel like you are sleeping on a cloud. They are highly breathable and wick moisture to make you feel relaxed all night long.

Why Sleep Number sheets matter for FlexFit owners
The FlexFit base articulates the head up to 60 degrees and the foot up to 35. Standard fitted sheets sized for a flat platform either pop off the corners or pull the mattress fabric. Sleep Number sheets include corner-anchor straps that loop under the mattress and hold the sheet flat through articulation. Owners who try to use third-party sheets on a FlexFit bed almost always switch to Sleep Number sheets within the first six months.
Split King and FlexTop King sizing
Sleep Number's Split King and FlexTop King configurations require special-cut sheets — Split King uses two separate fitted sheets (one per side), FlexTop King uses a single top sheet over two bottom sheets. Standard King sheets don't fit either configuration. All four Sleep Number sheet lines come in Split King and FlexTop King sizing.
Sleep Number sheets FAQs
Are Sleep Number's True Temp sheets worth it?
Many people who have used these True Temp sheets by Sleep Number are highly impressed by their performance. They are excellent when it comes to breathability and moisture-wicking.
So if you tend to sleep hot, these sheets will definitely work, and so do the ones that come with polyester, as they will keep you nice and cozy.
Does a Sleep Number bed require special sheets?
No, you don't have to go for any special sheets to make the Sleep Number beds work. You can use your regular sheets, too, if you want to save. But for the best results and size options, we highly recommend using these True Temp sheets.
Is there a guarantee on bedding with sleeping numbers?
Yes, your True Temp sheets come with a 30-night sleep trial and a 1-year warranty. Unfortunately, there aren't many brands available on the market that offer these perks on their bedding accessories.
Do Sleep Number Beds Need Special Sheets?
Sleep Number beds do not strictly require special sheets, but standard sheets often fit poorly due to the unique mattress dimensions. Sleep Number mattresses tend to be deeper than conventional mattresses - some models reach 12 to 15 inches in height - and their split-king configurations need two twin XL fitted sheets instead of one king sheet.
Here is what to keep in mind when choosing sheets for a Sleep Number bed:
- Pocket depth matters most: Measure your Sleep Number mattress height and buy sheets with a pocket depth at least 2 inches deeper. If your mattress is 12 inches, look for sheets with 14–15 inch pockets.
- Split king requires two fitted sheets: If you have a split king setup (two separate air chambers), each side uses a twin XL fitted sheet. You can still use one king flat sheet on top.
- Stretchy fabrics stay put better: Sheets with some elasticity - like jersey knit or sateen with elastic all the way around - grip the rounded corners of a Sleep Number mattress more securely than crisp percale.
- Avoid overly thick sheets: Very thick or flannel sheets can interfere with the feel of the adjustable firmness settings by adding a buffer between you and the air chamber.
Sleep Number sells branded sheets designed for their beds, but they are often overpriced for what you get. Quality deep-pocket sheets from any reputable brand will work fine.
Sleep Number: What Buyers Should Know Before Purchasing
Shopping for a Sleep Number mattress means weighing several factors that reviews alone cannot capture. Here is a practical framework for evaluating this brand against your specific sleep needs.
Questions to Ask Before Buying
- What is the trial period? Check whether the retailer or brand offers a risk-free trial. Anything under 100 nights limits your ability to properly evaluate comfort through different seasons and sleep cycles.
- What does the warranty actually cover? Read the fine print on sagging thresholds, stain exclusions, and foundation requirements. A warranty that sounds generous on paper may be difficult to claim in practice.
- How is the mattress delivered? Bed-in-a-box delivery means self-setup and potential off-gassing. White-glove delivery includes professional setup and old mattress removal.
- What do long-term owners say? Filter reviews by 1-year and 2-year owners. Initial comfort impressions often differ from long-term satisfaction.
How Sleep Number Compares on Key Metrics
Every mattress purchase involves trade-offs. Sleep Number may excel in certain areas while falling short in others. The most important factors for long-term satisfaction are durability (will it maintain support beyond year 3?), temperature regulation (will you sleep hot?), and purchase protections (can you return it hassle-free if it does not work?).
