What You Need:

Your Bed Frame:

If you want a set of sheets that are luxuriously soft, lightweight but still warm, this jersey sheet set might work well for you.

Optional Modular Base from Sleep Number:

If you do not want to bother with your own frame or want to use it, but do not feel like you can provide the proper support, you can always purchase one of Sleep Number’s modular bases or FlexFit bases. These can work as a stand-alone, or fit within your own existing bed frame.

Your Sleep Number Bed:

Obviously, your Sleep Number bed is soon to arrive or has arrived, and you should have room for it. As long as your frame and support is set up, you have the space to begin laying out your bed.

Step 1: Ensure Proper Bed Support

As mentioned above, you do need the proper support for your Sleep Number Bed. If you have purchased a bunkie board, make sure it is set correctly. If you have a base from the company, you will see that these come together simply with the rails snapping easily together. You may need a screwdriver to ensure the legs are on tightly, and if you have a ‘smart’ base, you will have to plug it in as well.

Step 2: Place Mattress Openings at Head of Bed & Unzip Bottom of the 2 Covers

The bottom of your mattress casing will have one, or two openings (depending on whether you have a dual system or not) at the head of the mattress case. You need to place these at the head of the bed in order to assemble your air system up properly.

The top of the bed also has two zippers, one atop the other, to access the different chambers of the bed. You need to unzip the bottom zipper and remove the covers in order to properly set up your air technology. This also allows unrestricted access to the bed for comfort and layering.

Step 3: If Applicable: Place Corner Lock System in Place

Some bed sizes, like the double bed, have a corner locking system instead of the notched side walls. These are placed on the bottom of the mattress cover in each corner. Without these your walls will not be stable, so make sure you have them in place. If you have notched side walls, then your bed will not have these locking systems.

Step 4: Place Foam Side Walls

Once you have your top open, you can easily begin to build the structure and support of your bed. First, you want to place the long foam side walls along each side of the bed if you do not have a corner locking system. You want to make sure the notches, located at the ends of each wall, are facing inwards in order to complete the rest of the wall support.

Step 5: Place End Walls

With the long foam walls in place, it helps hold up the structure of the mattress cover better as well, and you can easily slip in the foam walls for the head, and foot of the bed. With these placed properly, you have full access to the inside of the case, and the ability to begin layering the bed.

Step 6: Place Foam Base Pad

Now, you want to place the foam base pad into the bottom of the cover. Shake it out to keep any foam from folding upon itself and begin to lay it into the bottom of the cover. If there is a textured side and a smooth side, then make sure the smooth side is faced downwards.

Step 7: Install Air Chambers

The air chambers come next, and need to be laid over the base pad with the hose connectors facing the head of the bed and are along the bottom where the openings in the mattress casing are. Once these are lying flat, you need to zip them together if you are using a dual system to avoid getting a gap between the two.

Step 8: Set Up Firmness Control System

The Firmness Control System can now be set up and connected to the air chambers. Repeating for the right and left sides of the bed ( or center for single systems), connect the hoses together by pushing them until you hear a click- ensuring they have created a seal. You may have to feed, or pull, part of the hose through the opening, which is why they are there in the first place.

Step 9: Activate Dual Air Technology

Set your system either under your bed near the head, or to the side of your bed, and plugin. Make sure your remote has batteries and/or you have downloaded the app to your Smartphone and followed the online app setup instructions. Then turn on the system and fill both sides to 100. You want to start with your system fully inflated so you can set the rest of your bed layers up the evening before setting your own personal comfort levels later.

Step 10: Extend Border Wrap Over Walls

The border wrap over the foam border wall to comply with federal and state flammability requirements. This literally pulls over the edges and lays upon the top in a snug, but unsecure fit. This is important for how it fits with the rest of your layers.

Step 11: Attach the Mattress Cover But Leave Top Section Off

Now affix the bottom part of the mattress cover over the foam borders air system. This helps hold them in place and provides better stability for the above layers. You also will have to unzip the top duvet-like cover and put it to the side of you haven’t already.

Step 12: Place in Foam Comfort Layers

Now you can place the foam layers into the duvet casing. Make sure they are settled evenly, and the smooth side is facing down if you have a foam layer with texture. If you have a bed with a dual layer design you can place either comfort layer on top depending on our own preference, but always make sure the textured side is facing up.

Step 13: Extend Border Wrap Over Foam

The foam border wrap now extends over the entirety of the foam comfort layers. Again, to ensure your bed is in compliance with federal and state flammability requirements, and keep your mattress under warranty- you must have this done.

Step 14: Replace Mattress Cover Top

Now you can zip on the top of the duvet cover as the initial comfort surface prior to use. To close properly and easily, make sure the zipper pull is at the head of the bed and completely inserted into the zipper box, then zip closed.

Step 15: Adjust and Enjoy!

Now you can adjust your bed to your preferred Sleep Number Comfort Number, and with the use of the built-in sensors can begin to track your sleep movements, respiration, and heart rate. Allow yourself some time to adjust to a new bed, as well as the time it may take to find your perfect sleep number and comfort preference.

What is so great about the bed is that it can be readjusted as often as you need it depending on the variables that may change in your life- such as pregnancy, body and back pain, injury, or even as simple as something like a sunburn.


Even if you have only been considering a Sleep Number Bed, it is good to know in advance the time and effort it takes to put your bed together. Luckily, as you can see, the design of the bed is fairly simple, and literally layers upon one another easily in order create your bed support. Altogether, the bed arrives well boxed and easy to transport from one room to the next, making it a great choice for smaller spaces. If you need to move your bed at any point, it is also easy to disassemble.
