How to Restore and Fix a Sagging Memory Foam Mattress

Have you ever purchased a memory foam mattress and seen a noticeable sag after a year or so of use? Of course, you check the warranty, but the sag is not severe enough to merit a manufacturer’s repair or replacement. For more information, please visit

Do not overlook the issue! A drooping memory foam mattress will not provide the stability your body requires for restful sleep, and too many restless nights can hurt our health. Additionally, a bumpy mattress can increase pressure in somebody’s regions, leaving sleepers with back pain.

  • Examine the Foundation for the Mattress and the Bed Frame

If your memory foam mattress is sagging, the issue may be with your mattress base or bed frame. Mattress foundations and bed frames are designed to elevate the bed off the floor and support you and your mattress. Because memory foam is a heavier mattress material, it requires additional support. Without adequate support, sagging regions will develop.

A memory foam mattress base or bed frame should have a firm or slatted surface to withstand wear and tear. Slats should be spaced no further apart than 3 inches. Wider gaps lead the mattress to drop between them, creating an uneven surface and causing the bed to degrade.

The mattress guarantee details how the bed should be supported. Otherwise, harm caused by incompatible support voids the warranty. If you already have a mattress foundation and are hesitant to purchase another.

  • Flip or Tilt the Mattress

If you’re feeling body imprints from your sleeping position, just turning the memory foam mattress will alleviate the sagging. Every three months, mattress manufacturers recommend rotating your mattress. This approach balances out wear and tear on your mattress and may even increase its life.

Most current memory foam mattresses are constructed in a single piece, which means the mattress is not intended to be flipped. The comfort layers should be at the top of the bed, while the support layers should be towards the bottom. Flipping the mattress over to expose the comfort layer might cause damage to the bed and exacerbate sagging.

Only dual-sided memory foam mattresses may and should be tilt. Double-sided beds, as their names imply, feature two distinct sleeping areas. Each side has a varying degree of hardness. Other memory foam mattresses should never be flipped unless the manufacturer specifically states otherwise.

  • Add a Mattress Pad or Topper

The final option for repairing a sinking memory foam mattress is to add a mattress topper. It is not a long-term solution, as the topper will drop in the exact location of the bed. Mattress toppers are typically used to provide additional softness or firmness to an uncomfortable bed. However, they can provide additional support and serve as a temporary repair for a sagging mattress.

Memory foam, latex, and poly-foam mattress toppers are available. These materials fit the natural contours of your body and alleviate pressure areas. When your bed begins to droop, a latex topper, in particular, may be beneficial. Latex is more supportive than memory foam.

On the other side, poly-foam toppers are less expensive and less supportive. Additionally, they are not the best choice due to their shorter lifespan—less than a year compared to the three to five years of a latex topper.

Toppers for mattresses are available both online and in-store. In addition, certain mattress manufacturers create their toppers to complement certain mattress types. A mattress topper will cost between $20 to $250, depending on the material and size.

Mattress pads are thinner than mattress toppers and may not be as efficient at altering the feel of a bed as mattress toppers are. Mattress pads are frequently used as a mattress protector, minimizing the amount of wear and tear on the mattress. Mattress pads often comprise down, cotton, or polyester fibers and give more cushion than support.
