How Do I Stop My Memory Foam Mattress From Sinking?

Published in Mattress Care 3 mins read

To prevent your memory foam mattress from sinking, focus on even weight distribution and proper support. Here's how:

Strategies to Combat Mattress Sinking

1. Rotate or Flip Your Mattress

  • The Goal: Even out the wear and tear on your mattress. This prevents excessive sinking in areas where you consistently place the most weight.
  • How to Do It: Rotate your mattress 180 degrees every 3-6 months. If your mattress is flippable (double-sided), flip it over as well. This allows different sections of the memory foam to recover and prevents permanent indentations.
  • Why It Works: By regularly changing the orientation, you shift the pressure points, giving the memory foam a chance to bounce back and preventing localized sinking.

2. Improve Your Mattress Support

  • The Goal: Ensure your mattress has a solid and even foundation. A weak or uneven base can contribute to sagging and sinking.
  • What to Look For:
    • Slats: If your bed frame uses slats, make sure they are evenly spaced (typically no more than 2-3 inches apart) and securely attached. Replace any broken or damaged slats.
    • Platform: A solid platform bed provides the best support.
    • Box Spring (If Applicable): If using a box spring, inspect it for sagging or damage. A worn-out box spring can contribute to mattress sinking.
  • Solutions:
    • Add More Slats: Increase the number of slats to provide more support.
    • Reinforce Slats: Consider adding a center support beam to your bed frame if it lacks one.
    • Replace Box Spring: If your box spring is the culprit, replace it with a new one or switch to a platform bed.

3. Consider a Mattress Topper

  • The Goal: Add a layer of supportive material to distribute weight more evenly and potentially mask existing sinkage.
  • What to Look For: Opt for a firm mattress topper made of latex, high-density foam, or a supportive blend of materials.
  • Important Note: A topper can provide temporary relief, but it won't solve underlying support issues with the mattress itself or the bed frame.

4. Check Your Mattress Warranty

  • The Goal: Determine if your mattress is still under warranty and if sinking is a covered issue.
  • What to Do: Review your warranty documents carefully. Many warranties cover excessive sagging (usually defined as a certain depth of indentation).
  • Next Steps: If your mattress qualifies for a warranty claim, contact the manufacturer or retailer to initiate the process.

Additional Tips

  • Weight Distribution: Avoid consistently sitting or sleeping in the same spot on the mattress.
  • Proper Usage: Ensure you are using the mattress as intended and within its weight capacity.
  • Regular Maintenance: Vacuum your mattress regularly to remove dust and debris.

By implementing these strategies, you can help prevent or minimize sinking in your memory foam mattress and extend its lifespan.
