What Sleep Number mattresses are and how they differ from standard beds

Sleep Number is a mattress brand that sells adjustable air beds — mattresses filled with air chambers instead of springs or foam. The key difference is that you can change the firmness of your side of the bed using a remote control or a mobile app, without getting out of bed. Each side of a Sleep Number bed has its own air chamber, so two people can set different firmness levels.

The company calls its firmness scale "Sleep Number," which runs from 0 (very soft) to 100 (very firm). Most people sleep comfortably somewhere between 30 and 70, depending on body weight and personal preference. You adjust the number up or down until the bed feels right to you, and you can change it any night if you want a different feel.

Sleep Number beds come with a base that includes a motor to pump air in and out of the mattress chambers. The mattress itself sits on top of this base. Some models include features like built-in heating, cooling, or the ability to raise the head or foot of the bed, similar to an adjustable bed frame.

Key Takeaways

  • Sleep Number mattresses use air chambers you control with a remote or app, letting you change firmness without replacing the bed.
  • Each side of the bed adjusts independently, so partners can choose different firmness levels.
  • The mattress sits on a motorized base that pumps air in and out; you will need to plug the base into an electrical outlet.
  • Sleep Number beds cost significantly more than traditional mattresses, and the base and mattress may need repairs or replacement parts over time.
  • The company offers a trial period (length varies by location and promotion) so you can return the bed if it does not work for you.

How to set up and use a Sleep Number bed

When your Sleep Number bed arrives, the company typically handles delivery and setup, including removing packaging and positioning the mattress on the base. You will need a standard electrical outlet near the bed to power the motorized base. The base connects to your remote control or to the Sleep Number app on your phone via Bluetooth, which lets you adjust firmness from bed or across the room.

To find your starting Sleep Number, the company recommends lying on the bed and adjusting the firmness until it feels supportive but not too hard. Many Sleep Number stores have beds on display where you can test different numbers before buying. Once you choose a number, you can change it any time — there is no penalty for adjusting it nightly or weekly as your preference shifts.

Some Sleep Number models include a "FlexFit" base that lets you raise the head or foot section, similar to a hospital bed. If your model has this feature, you control it through the same remote or app. Other models include heating or cooling zones, which you also adjust through the remote.

Sleep Number bed sizes, models, and price ranges

Sleep Number sells beds in standard sizes: Twin, Twin XL, Full, Queen, King, and California King. The Queen and King are the most common purchases because they accommodate two people with independent side controls.

The company offers several model lines at different price points. Entry-level models have basic air adjustment and a standard base. Mid-range models add features like dual temperature control (heating on one side, cooling on the other) or a FlexFit base. Premium models include more advanced climate control, better mattress materials, or additional customization. Prices vary widely depending on the model, size, and current promotions; Sleep Number frequently runs sales and financing offers.

You can purchase a Sleep Number bed directly from Sleep Number stores, their website, or through some third-party retailers. The company often offers trial periods (typically 30 to 100 nights, depending on your location and the current promotion) during which you can return the bed for a refund if it does not meet your needs.

What happens if your Sleep Number bed needs repair or replacement parts

Sleep Number beds come with a warranty that covers defects in the mattress and base for a set period (typically 10 years for the mattress and 5 years for the base, though this varies). The warranty does not cover normal wear, damage from misuse, or stains.

If the mattress develops a leak or the base stops working, you contact Sleep Number customer service to report the problem. The company may send a technician to repair it, ship you a replacement part, or in some cases replace the entire mattress or base. Repair or replacement under warranty is typically free, but out-of-warranty repairs or parts cost money.

Sleep Number also sells replacement air chambers, remote controls, and other components if you need to fix something yourself or want a spare part. These are available through the company's website or customer service line.

Ongoing costs beyond the initial purchase

After you buy a Sleep Number bed, there are a few costs to keep in mind. The motorized base uses electricity whenever it is plugged in, though the power draw is relatively low — similar to a lamp or small appliance. You do not need to unplug it daily, but unplugging it when you are away for an extended period can save a small amount on your electric bill.

If you want to add features later — such as upgrading to a model with temperature control or a FlexFit base — you may be able to purchase these as add-ons, though the cost and availability depend on your current bed model and Sleep Number's current offerings. Mattress covers and sheets designed for Sleep Number beds are sold separately and cost more than standard bedding because of the adjustable design.

If the warranty expires and a part fails, out-of-warranty repairs can be expensive. Some people choose to purchase an extended warranty at the time of purchase to cover repairs beyond the standard warranty period.

How Sleep Number beds compare to traditional mattresses

A traditional mattress has a fixed firmness — you choose one level when you buy it, and it stays that way. If you do not like the firmness after a few months, you have to buy a new mattress. A Sleep Number bed lets you adjust firmness when ready, which can be useful if your preferences change or if you and your partner have different needs.

Traditional mattresses are usually cheaper upfront than Sleep Number beds. A quality innerspring or foam mattress may cost $500 to $2,000, while Sleep Number beds typically start around $1,000 and go significantly higher for premium models. However, if you keep a Sleep Number bed for many years and avoid replacing it because you can adjust it instead, the long-term cost may be comparable.

Sleep Number beds require electricity and have motorized parts that can fail, whereas traditional mattresses have no moving parts. This means Sleep Number beds need more maintenance and may have repair costs that a traditional mattress would not. Traditional mattresses can also be donated or discarded more easily at the end of their life, while a Sleep Number base requires proper disposal because of its electrical components.

Things to consider before buying a Sleep Number bed

Before purchasing, test a Sleep Number bed in a store if possible. Lie on it for several minutes at different firmness levels to see if the feel works for you. Some people find air beds uncomfortable because they feel different from foam or spring mattresses, even after an adjustment period. The trial period offered by Sleep Number exists partly for this reason — not everyone adapts to an air bed.

If you have a partner, make sure you both test the bed and agree on the purchase. Independent side controls are a major selling point, but if one person's Sleep Number setting causes the other side to feel unstable, it can create problems. Test this in the store if the display bed allows it.

Check whether your bedroom has a nearby electrical outlet for the base. If not, you may need to run an extension cord, which is possible but less convenient. Also consider the noise level — the motor that adjusts firmness makes a humming sound, which some people find noticeable and others do not notice at all. Ask to hear it running in the store.

Review the trial period terms carefully. Some trials are 30 nights, others are longer. Understand the return process, any restocking fees, and whether you have to arrange pickup or if the company handles it. Also check the warranty details and whether extended warranty options are available at purchase.

Frequently Asked Questions

Can I use regular sheets on a Sleep Number bed?

Yes, regular sheets work on most Sleep Number mattresses because the top surface is similar to a standard mattress. However, because the mattress is thicker than many traditional mattresses (due to the air chamber underneath), you may need deeper pockets or sheets labeled as fitting thicker mattresses. Sleep Number sells proprietary sheets designed for their beds, but they are not required.

What if the air chamber leaks?

A slow leak will cause the mattress to gradually lose firmness over days or weeks. You may notice one side becoming softer than the other. Sleep Number can locate the leak and patch it, or replace the air chamber if patching is not possible. Small leaks are often repairable; larger ones typically require a replacement chamber or mattress. This is covered under warranty if the leak is a manufacturing defect.

Do Sleep Number beds work with adjustable bed frames?

Sleep Number beds come with their own motorized base, which is different from a standard adjustable bed frame. You should not place a Sleep Number mattress on a different adjustable frame because the mattress is designed to work with the Sleep Number base. If you want an adjustable bed, you need to purchase a Sleep Number model that includes a FlexFit base.

How long does a Sleep Number bed last?

Most Sleep Number mattresses last 8 to 10 years with normal use, similar to traditional mattresses. The motorized base may last longer or shorter depending on how often you adjust it and whether parts fail. The warranty typically covers 10 years for the mattress and 5 years for the base, but this varies by model and purchase date.

Can I move a Sleep Number bed to a new house?

Yes, Sleep Number beds can be moved, but the process is more involved than moving a traditional mattress. The base is heavy and requires careful handling to avoid damaging the motor or electrical components. Many people hire professional movers for this reason. You will also need an electrical outlet in the new location. Some Sleep Number stores offer moving services or can recommend local movers experienced with their beds.
