Applies to Modular Bases only.
Quick answer: If your bed dips in the middle, inspect the modular base support beams, decking panels and legs or bed frame. Stop using the base if you see bowed, broken, warped or damaged parts, and contact Sleep Number Customer Support for help with replacement parts.
A Sleep Number modular base is designed to provide strong, even support for your mattress, up to 400 pounds per side. Use the steps below to check your base if your bed feels uneven, sags or has a dip in the center.
Before you start
You may need a flashlight. If your modular base sits inside furniture, carefully remove the mattress and base coverlet so you can see the base, support beams and decking panels.
Inspect the modular base
-
Check the horizontal support beams under your modular base. Use a flashlight to look for bowing, cracks or breaks.
- If your base is enclosed inside furniture, remove the mattress and base coverlet first.
- Lift and pull the decking panels away from the base to expose the support beams.
- Check the decking panels. Make sure each panel is straight and look for warping, cracks or other visible damage.
-
Check the legs or bed frame supporting the modular base.
- If you use a bed frame, make sure the center of the modular base is fully supported.
- If you use Sleep Number legs, make sure all bolts and nuts are securely fastened.
- If you find bowing, breaks, warping or other damage, stop using the modular base and contact Sleep Number customer service for replacement parts. For safety, place your mattress on the floor until the damaged parts have been replaced.
When to contact Sleep Number Customer Support
Contact Sleep Number Customer Support if any support beam, decking panel, leg or frame part looks damaged, bowed, broken or unstable. Customer Support can help confirm the part you need and review available replacement options.
