Foam Side And End Wall Troubleshooting

Applies to: Traditional Sleep Number® mattresses, purchased prior to 2017.

The foam side and end walls help support the edges of your Traditional Sleep Number® mattress and keep the mattress shape. If a foam wall is torn, softened, flattened, bulging or no longer supporting the edge of your mattress, use these steps to check whether it may need to be replaced.

Before you begin

• Remove all bedding from your mattress.
• Use your remote to set both sides of your bed to 100 while no one is in the bed.
• If you have a FlexFit adjustable base, make sure the base is flat before opening the mattress.

Check your foam side and end walls

1. Open your mattress cover

• Find the zipper at the head of your bed and unzip the mattress cover completely.
• If your mattress has two zippers, unzip the top zipper first.
• Remove the top panel of the mattress cover and set it aside.
• If your bed does not look like these instructions, or your owner’s manual does not match what was delivered, contact us for help identifying your model before continuing.

2. Inspect the foam walls for damage

• Carefully remove the foam side or end wall you want to check.
• Look for tears, rips, cracks, flattened areas, soft spots or areas where the foam is bulging out of shape.
• Squeeze one end of the foam wall between your hands, then squeeze several spots near the center.
• If the center feels softer, thinner or less supportive than the end, the foam wall may need to be replaced.
• If the top surface of the mattress is bulging, one side is flat, your remote will not pair or your bed is rocking, this article may not solve the issue. Contact us so we can help route you to the right troubleshooting steps.
