Inflating a Sleep Number mattress without a cover is not recommended
Sleep Number mattresses are adjustable and allow users to find their desired level of firmness. They are airbeds that hook up to a hose and pump, allowing users to inflate or deflate the bed to their preferred comfort level. The Sleep Number setting ranges from 1 to 100, indicating the softness or hardness of the mattress.
While Sleep Number mattresses offer innovative features, they also come with certain complexities in maintenance and care. When it comes to inflating the mattress, it is not recommended to do so without the cover. Here's why:
Firstly, the cover plays a crucial role in maintaining the shape and structure of the mattress. Without the cover, the mattress may inflate unevenly, resulting in an unbalanced sleeping surface. The cover provides a contained space for the air to distribute evenly, ensuring a consistent firmness throughout the bed.
Secondly, the cover also serves as a protective layer for the internal components of the mattress. Removing the cover exposes the hoses, air chambers, and other mechanical parts to potential damage. The cover acts as a barrier, protecting these components from wear and tear, as well as external elements such as dust and moisture.
Additionally, attempting to inflate the mattress without the cover can be unsafe. Sleep Number mattresses use strong magnets in their construction, particularly in the Smart Beds with a FlexFit™ Smart Base. These magnets can pose a risk of pinch injury if they come into close contact with each other or other metal objects during the inflation process. The cover helps to enclose these magnets and minimise the risk of injury.
Furthermore, the process of inflating the mattress without the cover can be challenging and time-consuming. The cover provides convenient access points, such as zippers, to reach the hose connections for inflation. Without the cover, accessing these connections and ensuring proper hose attachment can become difficult and cumbersome.
Lastly, the cover is an integral part of the Sleep Number mattress system. It is designed to work in conjunction with the internal components to provide a comfortable and personalised sleeping experience. By removing the cover, you may compromise the intended functionality of the mattress, potentially affecting your sleep quality and the longevity of the product.
In conclusion, while it may be tempting to inflate your Sleep Number mattress without the cover, it is strongly advised against. The cover serves multiple important purposes, from ensuring even inflation and protecting internal components to enhancing safety and facilitating convenient maintenance. Always refer to the manufacturer's instructions for proper care and maintenance of your Sleep Number mattress.

Unzip the mattress cover to access the hose connections
Sleep Number mattresses are known for their adjustable air chambers, allowing users to inflate or deflate the bed to their desired comfort level. While the specific steps for disassembling the mattress may vary depending on the model, here is a general guide on how to unzip the mattress cover to access the hose connections:
Unzipping the Mattress Cover:
- Locate the Zipper(s): Depending on the model, your Sleep Number mattress may have one or two zippers. The zipper(s) are typically located at the head of the bed. If your mattress has two zippers (usually for a Duvet-style mattress), you will need to unzip the bottom zipper first.
- Unzip the Mattress Cover: Once you have located the zipper(s), proceed to unzip the mattress cover all the way around. This will allow you to access the internal components of the mattress, including the hose connections.
- Remove the Top Panel: After unzipping the cover, carefully remove the top panel or foam comfort pad to expose the underlying structure. This step may vary depending on the specific model and design of your mattress.
Accessing the Hose Connections:
- Locate the Hose Connections: With the mattress cover unzipped and the top panel removed, you should be able to see the hose connections. They are usually located at the head of the bed, near the pump.
- Disconnect the Hoses: Before making any adjustments or inspections, disconnect the hoses from the pump and air chambers. Gently pull on the hoses to ensure they are securely connected. If you need to remove the hoses completely, refer to the next step.
- Remove the Hoses: To remove the hoses, locate the gray tab where the hose meets the air chamber. Push in the gray tab and gently pull on the hose to disconnect it. Repeat this step for all hoses, as some models may have more than one hose per chamber.
- Inspect for Damage: With the hoses disconnected, you can now inspect the air chamber and hose connections for any signs of damage, such as cracks or breaks. Ensure that the O-rings are present and intact.
- Reconnect the Hoses: If no damage is found, reconnect the hoses by gently pushing them back into place until you hear a click. If there are any issues with the hose connections or air chambers, contact Sleep Number support for further assistance.
It is important to note that you should not attempt to take apart your Sleep Number mattress beyond the steps provided by the manufacturer. Always refer to the official instructions or seek support from Sleep Number when performing any maintenance or repairs. Additionally, some models may have specific variations in the disassembly process, so it is crucial to consult the relevant resources for your particular mattress model.

Disconnect the hoses and cap the air chamber
Disconnecting the hoses and capping the air chamber is a crucial step when moving or troubleshooting your Sleep Number bed. Here is a detailed guide on how to do it:
Locate the Hose Connections:
First, you need to find the hose connections. If your Sleep Number bed has hose connections at the head of the bed, you will need to unzip the mattress cover to access them. For duvet-style beds with two zippers, unzip the bottom zipper and fold back any foam comfort pad to expose the hose connections.
Disconnect the Hoses:
Once you have located the hose connections, it's time to disconnect the hoses. Look for the tab at the end of the hose and push it in while gently pulling on the hose to disconnect it. Air will start to release from the chamber immediately. Repeat this step for all hoses. If your bed has more than one hose per chamber, ensure you remove them all.
Cap the Air Chamber:
As soon as you disconnect a hose, cap the corresponding air chamber to prevent it from deflating. You may need two caps if your air chamber has two connection points. The caps are usually stored inside the mattress, the base, or near the pump. If you cannot locate the caps, you can purchase them from a Sleep Number store or order them online.
Inspect for Damage:
Before capping the mattress, it is a good idea to inspect the disconnected hoses and air chamber connections for any damage, such as cracks, breaks, or missing/damaged O-rings. If you find any issues, contact Sleep Number support for further guidance.
Reposition the Foam and Cover:
After capping the air chamber, reposition the foam and top cover panel on the mattress. Zip the cover closed, ensuring everything is securely in place.
Disconnecting the hoses and capping the air chamber is an essential step when preparing your Sleep Number bed for moving or troubleshooting air loss. Remember to follow the manufacturer's instructions and take your time during the process to avoid any damage to your bed.

Inflate the mattress to 15 points higher than your preferred setting
Sleep Number mattresses are air beds that hook up to a hose and pump, allowing users to inflate or deflate the bed to their desired comfort level. Each user gets their own "Sleep Number", a number between 1 and 100 that indicates their preferred mattress firmness.
If your Sleep Number mattress is losing air, you can attempt to rectify the issue by capping your mattress. First, check for any broken or damaged parts. If you do not find any, proceed to capping your mattress. If you have white air chamber caps, you can use those. They are usually stored inside the bed near the pump or head of the bed. If you cannot find them, you can purchase them from your local Sleep Number store or order them online.
If you notice air loss on one side of the bed, inflate that side 15 Sleep Number setting points higher than your preferred setting. You will lose some air when you disconnect the hose, so quickly cap the chamber after. If your air chamber has two connection points, you may need two caps.
Next, reposition the foam and top cover panel on the mattress and zip the cover closed. You can sleep on your mattress with the air chambers capped for 1-3 nights. If you notice a change before this period elapses, contact Sleep Number support to determine the next steps.

If the mattress is losing air, check for breaks or damage
If your Sleep Number mattress is losing air, the first thing to do is check for any damage or breaks. Sleep Number mattresses are air beds that hook up to a hose and pump, allowing you to inflate or deflate the bed to your desired comfort level.
If you notice a loss of firmness after each night of sleep, or the pump is running constantly, there may be an issue with the pump or a loss of air. First, check the power cord is properly connected and the pump is plugged into a working outlet. If the pump is not the issue, the next step is to check the hoses. Ensure they are securely connected at the pump and the chamber. If the hoses are uncoupled, or the coupling is loose, this could be the cause of air loss.
If there is no visible damage, and the pump and hoses are connected, the next step is to cap the mattress. Find the white air chamber caps, usually stored inside the bed near where the hoses exit. If you do not have caps, you can purchase them from a Sleep Number store or online. Inflate the side of the bed with air loss to 15 points higher than your usual setting, disconnect the hose, and quickly cap the chamber. If your air chamber has two connection points, you may need two caps.
If the mattress holds air with the caps on, leave them in place. If not, swap the hoses if only one side is losing air. If the mattress is still losing air, contact Sleep Number support for further troubleshooting.
