What Is a Sleep Number?

A Sleep Number is a setting on how soft or firm you want your bed to be. The numbers usually range between 1-100, with firmer mattresses in the higher spectrum. Being adjustable and customizable, you can choose the settings through a button or by syncing the app on your phone and adjusting it from there. This customization is possible thanks to the air chambers connected to a hose that you can pump to increase or decrease the air within them to your preferred firmness. The air chambers typically have a weight limit of 400 pounds each. Depending on its size, a bed can either have one or two air chambers.

Based on surveys, most users prefer Sleep Numbers within the 35-45 range, which provides enough firmness for ample support and pressure relief.

Sleep Number Bed Weight Limit for Different Bed Sizes

The Sleep Number bed’s weight limit depends on its size. Typically, this kind of mattress is available in standard sizes. As a reference, here are the weight limits according to type:

Sleep Number Bed TypeSleep Number Bed DimensionSleep Number Bed Weight Limit
Twin38” x 75”400 lbs (one air chamber)
Twin Long38” x 80”
Full54” x 75”
Double54” x 75”
Queen60” x 80”800 lbs (two air chambers)
King76” x 80”
California King72” x 84”

Aside from the standard bed sizes, Sleep Number beds also come in unique variations such as Split King, FlexTop King, and FlexTop California King. The FlexTop King and California King options come within the same dimensions as a King-sized or California King-sized bed, which can be split, lowered, or raised by the head of the bed. Meanwhile, the Split King option is two separate XL mattresses allowing the users to lower or raise their bed separately from the other side.

Best Sleep Number Settings

Because of its adjustable settings, you can get a restful sleep, depending on your needs and how you prefer to sleep. For example, if you’re a stomach sleeper, you will need a medium to firmness ratio that will prevent you from placing pressure on your ribs and stomach while also maintaining proper alignment along your spine.

  • Stomach sleepers – For stomach sleepers, the most recommended range is at around 50, while sleepers usually adjust it around this number.
  • Back sleepers – Back sleepers, on the other hand, find it most comfortable when the bed supports the arch of their backs. Models i7 and i8 in the Innovation series usually provide this kind of comfort due to the five-to-six-inch comfort foam layer placed on top of the air chamber. Combined with a setting of 50, the bed offers a medium firmness.

Sleep Number Beds for Back Pain

Sleep Number beds are also a big hit among people who usually feel lower or upper back pain in the morning. Side sleepers who experience this kind of pain typically assume a fetal position with pillows between their knees to minimize pressure around the hip and back area, while setting the firmness to their preferred range. The Coop Home Goods Premium Adjustable Loft Pillow (view on Amazon) is perfect for support. Like the Sleep Number bed, you can adjust it to your liking.

Meanwhile, for stomach sleepers, placing a soft pillow under the lower abdomen or the pelvis area can decrease pressure in your stomach and back.

Back sleepers are advised to place a soft pillow in the lower back or under the knees. If the discomfort isn’t alleviated, it is best to increase the Sleep Number to around five to ten points.

Sleep Number Bed Weight

Although the Sleep Number bed weight limit is quite high, it is relatively lighter than conventional mattresses. This is because the mattress is significantly composed of air. Depending on the bed size, Sleep Number mattresses weigh between 37 lbs to 120 lbs. Because of its low Sleep Number bed weight and the convenient assembly and disassembly of its parts, it is also easier to handle, transport, and move around.

Can a Heavy Person Use a Sleep Number Bed?

With a weight limit of 400 pounds per air chamber, a Sleep Number bed can comfortably accommodate people 230 pounds and above. According to a study conducted on users of Sleep Number beds, people with heavier weight tend to find models i8, i9 and i10 to satisfy their needs. In terms of comfort, the preferred firmness for people in the heavier weight range is right around Sleep Numbers 70-80. Your firmness preference might also change if you have recently gained around ten pounds or more. To make your mattress more comfortable, try adjusting your Sleep Number settings to increments of five points until you can achieve your preferred firmness.

Air Loss, Leaks, Air Chambers, Firmness

Being an air mattress, Sleep Number beds also experience some leaks and air loss from time to time. These occurrences can be caused by environmental factors that affect the consistent flatness of the mattress’s surface. If you have noticed that your Sleep Number bed sinks in the middle, or other possible air loss concerns, you can:

  1. Locate the leak by inflating the bed about 15 points higher than its normal height
  2. Take off the beddings and top layers of the mattress
  3. Locate the air system, which connects the hose to the air chambers where the air flows. Use a hose compatible with your Sleep Number bed. This heavy-duty hose (view on Amazon) is 5 feet long, airtight, and snug-fitting. It’s also translucent to match the surroundings.
  4. Once you locate the hose, gently tug it and see if it is loose.
  5. If it moves, screw the hose tightly.
  6. If it is secure and you have checked that air has not been leaking out from the hose connection, the next step is to check the Firmness Control system.
  7. Look for the white closure caps, which you can usually find inside the bed. You can get them from the manufacturer’s store or website.
  8. Push the grey tab at the top of the hose and pull it to disconnect it from the hose.
  9. Close the hose off with the white closure cap
  10. Locate for tears, holes, and other signs of damage within the nearby areas, including the hose area.
  11. Use the patching kit that comes with your mattress if you have identified a tear or a leak.
  12. Another thing that you have to look for is the black rubber O-ring and make sure that these connectors are in place.
  13. If there are no O-rings, replace the connector with another set.
  14. Test the bed out for a few nights, and if there are no issues, you can assume that the problem was within the firmness control system.
  15. If the problem persists, or if you didn’t find any leaks or tears, the next step is to check for leaks in the air chamber.
  16. In this type of leak, the issue is more internal and will require professional services from the Sleep Number store.

Sleep Number Bed Squeaks

Other than leaks and air loss, another possibility that you might encounter is the squeaking on your Sleep Number bed. This does not indicate that you have reached the Sleep Number bed weight limit. In most instances, it can be caused by the base rubbing on the metal bed frame or when the bed frame itself is loose. To resolve this, you can tighten the sleep number bed frame to get rid of the squeaking noise. However, if the noise persists, you can also use the legs to give your bed height rather than use a bed frame by simply attaching the legs in the mattress’s modular base.

Another common cause of noise coming from the bed is when you are adjusting the Sleep Number settings. Since this is an inherent characteristic of the bed and is not a sign of damage, one thing you can do is place the Firmness Control System on top of a carpet or a rug to minimize the chances of the sound echoing on the hard floor.

Sleep Number Bed Sinks in the Middle

You might also notice slight valleys or sagging in the center for mattresses that come with two air chambers. To resolve this, check if the foam comfort layer where you usually lie on is less supported, softer, or thinner than the rest of the pad. To do this, you will need to open the mattress from the top cover panel then place the foam between your hands to inspect its current condition. If you notice that the foam has lost its support, you can contact your local Sleep Number store to request a replacement. In other instances, fluff the foam comfort layer by holding the top cover panel and shake it to even out the distribution. Make sure that you do this step on all four sides, and zip the cover back.

Use a Wireless Air Bed Pump (view on Amazon) compatible with your Sleep Number mattress to adjust its air chambers. This pump comes with a wireless remote that has custom setting options to help you find your exact comfort level.
