How Do I Fix A Sagging Mattress: 6 Hacks For A Better Sleep

Article Summary:

As soon as your mattress starts becoming saggy, it is slowly affecting your comfort and sleep without you even realising. The smallest sag of the mattress will lead to painful feelings, improper posture, and sleepless nights.

This article covers information on how do I fix a sagging mattress, and will provide you with some amazingly simple methods to obtain better support at home.


Unless the mattress helps to support the human body in the appropriate way, it will cause discomfort when sleeping.

The issue is not noticed in the beginning by most people. Many times, it starts with very subtle changes in comfort, such as a little sag, that become more apparent as the days go on. As time goes on, this becomes increasingly visible and causes pain around your hips or lower back.

This is when you begin to wonder how do I fix a saggy mattress without being forced to head out and acquire a new mattress.

However, the response will rely on the problem and at what stage it is.

What Is The Reason For Mattress Sagging?

Mattresses do not normally sink without a purpose. Being aware of the cause of the dip may assist in taking the next step.

  • Body Weight Settles Into The Same Area

Pressure is absorbed by your mattress when you sleep. Because the majority of individuals sleep in the same position, some portions of the mattress deteriorate more than others.

That is why sagging will tend to occur on the hips, shoulders, or lower back initially.

  • Foam And Spring Loose Support Over Time

No mattress keeps the same feel forever.ย Foam layers often soften gradually, whilst springs lose tension after years of repeated pressure. Once this happens, the mattress struggles to distribute weight properly.

  • The Bed Frame Could Be The Source Of The Issue

In many cases, it is not the issue with the mattress.

When the foundation beneath is poor with slats and unequal support, the mattress will begin to lose support and structure slowly. Even with a relatively new mattress, this could happen.

  • The Mattress's Support Slowly Reduced

The majority of the mattresses retain their form and support for about 7 to 10 years. Sagging becomes much more common after that time.

  • Signs You Have A Sagging Mattress

Before your mattress starts to sag, you may already notice these few signs:

  • A dip in the middle or side
  • Feeling like you roll into one spot
  • Waking up with stiffness
  • Uneven support when lying down

When you have one of such problems, you can think of how do I fix a sagging mattress properly.

6 Tips That Help You Improve A Sagging Mattress


In case you are trying to find out how do i fix a sagging mattress, you should know that sometimes altering it in the slightest way is enough. These methods are not so much to fix the sagging itself but to make the mattress feel easier to sleep on.

  • Minimise Irregular Dips By Rotating The Mattress

Your daily sleeping position can cause stress on the same areas of the mattress. Eventually, those regions may begin to sink below the surface.

Rotating the mattress 180 degrees from head to foot redistributes most of the pressure in order to prevent the wear of one part over another. Itโ€™s a simple step, but it can make a difference if youโ€™re wondering how do i fix a sagging mattress early on.

  • Flip It, But Only If Itโ€™s Designed for It

There are some mattresses that can be flipped from time to time to help them wear more evenly. This is primarily helpful with double-sided mattresses that have both sides made for sleeping on.

But there are many mattresses that are just designed for one side. One should not flip up a:

  • Pillow-top mattress
  • Latex mattress
  • Pocket sprung mattress
  • Hybrid mattress
  • Cool gel memory foam mattress

Typically, the care label will tell you whether or not the mattress is flippable. When there is no writing there, the product instructions might have the answer.

  • Use a Topper To Alleviate Pain

In case there are uneven parts of the mattress, a topper will soften the feel when you are lying down. It can also relieve the pressure on the hips and shoulders. While it wonโ€™t repair the inside of the mattress, it can make sleeping more manageable for the time being.

This is often one of the easiest options people try when thinking about how do i fix a sagging mattress without replacing it straight away.

  • Make Sure The Bed Base Is Still Supporting Well


The problem is sometimes not caused only by the mattress. When the underlying slats are not strong enough or the holes are excessive, the portions of the mattress may begin to sink more quickly than the rest of the mattress.

In many cases, switching to a reinforced platform base may help make the mattress feel more even and not allow the sagging to get as bad as soon.

  • Try To Use Pillows To Level The Surface

Lying on a mattress which slopes in one area may be uncomfortable for the lower part of the back or the hips. There are individuals who use pillows to create a relatively smooth surface at night.

For example:

  • Under your hips, if the middle sags
  • Between your knees to reduce pressure
  • Along your lower back for added support

This is just a temporary measure to make the bed a lot more comfortable to sleep on till the sagging remains.

  • Be Sure To Read The Warranty First

The mattress may start to sink before the period, but it can be covered up, and you should check the warranty before mattress replacement.

Some businesses will replace a sagging mattress, but, in certain circumstances, the extent of the sag or the bed base type may have an influence.

Sagging Mattress? How Does It Affect Sleep?

When your mattress has started to sink, this may cause a change in your sleep during the night. In due course, it might turn out to be more difficult to feel comfortable or sleep without stiffening up.

It can:

  • Disrupt your sleeping position
  • Put pressure on certain joints
  • Affect posture while you sleep
  • Leave you waking up feeling tired or stiff

This is frequently the reason for sleep becoming less comfortable, even though the mattress may appear to be in great condition on the outside.

The issue for some people is a lack of support under them. Others will notice the mattress has become an uneven surface and feels firmer around the pressure points.

Sometimes adding extra cushion around the areas that don't feel comfortable can lead to a more comfortable surface to sleep on. A cheap pillow top mattress, in some cases, can feel a lot softer in areas of pressure.

Conclusion

Even when the mattress sags only a bit, it might appear that all is okay with a few adjustments, so you are not eager to replace it immediately.

But, when its interior starts falling apart, it is generally the time when you notice that whatever you do, your mattress should be replaced.

FAQs
