Sleeping on a sagging mattress can be terrible and discomforting. It may even be depressing to find your mattress sagging just a week after purchase.

We can imagine the terrible back and neck pains you wake with, as a result of having slept in what feels like a pothole. 

To fix a sagging mattress, remove the bed cover. Check the sagging areas with tape or yardstick. Move the mattress from the box spring or bed foundation. Get plywood. Place it on the bed foundation. Flip the mattress and place it back on the bed frame. Check again to ensure it is balanced.

Most of these really expensive mattresses do not last anymore, but it is possible that you may have picked the wrong ones. Whatever the case may be, having a sagging mattress is generally an albatross.

The dangers of sleeping in a sagging mattress is that it causes

1. Back pain

2. Unrest.

3. General body weakness

4. Body stiffness

Often, we like to attribute all the pain to old age but most often it’s the fault of the mattress. We seldom pay attention to back pain probably because it can be triggered by so many things.

However, when it comes to waking up to or with a pain in the back, it should be treated with urgency. It is a very crucial indication that the mattress should be checked. This is especially so if the back pain or stiffness goes away in the course of your daily routine.

Sagging mattresses could be the main cause of spinal stiffness or pain. You know, humans spend at least one-third of the whole 24 hours of the day sleeping. Now, that is about 7-9 hours that your spine could be bent or positioned wrongly. This can definitely affect the muscles and blood flow.

Sleeping in a sagging mattress also contributes a certain quota to some sleeping disorders and sleep habits.  These include sleep apnea, insomnia, and blockage of the airway.

In addition to sagging mattress being the cause of bad sleep habits, body aches, and pains, it is also pretty bad for sex. The lumpiness and indentations cause really awkward movements and discomfort during sex.

The wearing out and deteriorating of the mattress or bed spring creates a squeaky sound under body weight.

How Do You Ascertain the Sagging Areas in Your Mattress?

You can ascertain the sagging areas of your mattress by following these steps:

1. Lay a flat yardstick on the surface of the mattress

2. Move the yardstick horizontally to look for gaps beneath it.

3. Check for any area that has a wider gap, that is the sagging area

The sagging areas are commonly where we lay our heavy body parts like the hips, the head, and the shoulders.

You could run over the mattress with your hands to feel for the hard, lumpy areas of that mattress. Additionally, you could also discover that the springs under your mattress feel slightly different or have started poking through.

Could Some Mattresses Be Worse Than the Rest?

Some mattresses are not worse than the rest. All mattresses sag, the only difference is the time. Latex mattresses take a longer time before they begin to sag. Memory foam mattresses and inner spring mattress tend to sag after a long while.

Truth is, there really is no particular mattress that will not sag either now or in the future. Latex mattresses, foam mattresses, traditional mattresses, even padded comfort will eventually all tend to become softer than they used to be.

This could also give room to reduced or no support and compression. The traditional spring mattress is likely to also at some point lose a large part of its coil tension due to use. This will make it less bouncy and uncomfortable.

More so, the king and queen-sized mattresses, due to their largeness, are more susceptible to sagginess.

Nonetheless, high-quality and firm mattresses will less likely succumb suddenly to sagginess because the materials they are made with are a lot denser. This helps to extend their life span.

Can A Sagging Mattress Be Fixed?

A sagging mattress can be fixed temporarily. This may not be a lasting solution. It can be fixed by using plywood, mattress topper, or pillows. These options do not last. Getting a new mattress a more viable alternative in severe cases

We do not advocate for throwing away things that could be fixed. So, what we can try to do is mask most of the discomfort that makes sleeping pretty hard and uncomfortable.

Not all sagging mattresses are still in a fixable shape.

Now, this is where this article comes in very handy for you. We will be showing you some helpful tips to fix your sagging mattress.

A mattress topper comes in various sizes and with amazing features like pressure-relieving, cooling, even scented. The sheets and mattress pad fit perfectly over almost everything.

However, it does not promise to take all the indentation away. But it will do a good job at evening out the indentation and taking off most lumps. This will make the sagging mattress a lot more comfortable to sleep on.

A Mattress Helper

This will help the sagging problem somewhat. It functions by lifting the mattress up along the sagging places.

It will also assist in propping up the indented points. It needs to be properly placed under the points or areas where the foam is indented.

This is usually a very handy option for sure if the sagging problem is just not so severe. But note that this option will not take all the sagging problem away if it is a bit too severe.

Mattress Pad

A mattress pad will definitely resolve the sleeping problems associated with having a lumpy or saggy mattress. It helps especially, to stabilize the lumpiness on a dorm mattress or lumpy mattress. It is best used on a very soft bed.

The Pillow Fix

You should definitely opt for this, using the firm gel pillows. It works really well, and it is super long-lasting. All you need to do is lift your mattress and shove the pillows under each of the indented sides in your mattress.

Put down your mattress. Try lying back on them a bit to be sure your firm gel pillows are properly fixed at the indentation points.

If you are using cheap pillows, it will give you some comfort, but for a very limited time. This is because it will not take so long before it gets all squashed down like some pancakes. In the end, you will be back to the first square.

What are Other tips on how to fix your sagging mattress?

Other tips on how to fix a sagging mattress include:

1. Rotating your mattress to 180 degrees

2. Using a bed floor or double layer plywood

3. Changing your bed foundation or bed frame

4. Using an air bladder instead of a pillow

You can try to rotate your sagging mattress to 180 degrees. You could also flip it to the other side if it is a double-sided foam mattress.

This will make it possible for your body to apply the same pressure to diverse areas of the mattress. Sometimes, this helps as the mattress weight will be redistributed.

If your mattress is the pillow top or no-flip type, it is best to try turning the bed around. Do this in such a way that the position that was at the head part goes to the foot part.

This should also have the same weight distribution effect so hopefully, your pillow top mattress will even out.

Also, try using a bed floor or double layer plywood under your mattress. For a bit more reinforcement, you should cut the plywood to be the same size as your mattress.

Place it such that it covers the entire bed. This is normally about one inch thick. This should support sagginess but will make the mattress a bit harder.

Constantly check your bed springs if you are using a box spring bed. If the springs are bad or broken, they can no longer be supportive to the mattress.

Test this by having someone of little weight (like kids) walk around on top of the box spring a little bit.

Use or change your mattress foundation. If you were not using a mattress foundation, you should try getting one. They usually have four to six legs especially for a king- or queen-sized mattresses.

Some large mattresses need the owners to support them with foundations for optimized reinforcement.

Try using an air bladder in the stead of a pillow. This should work better because of the strength in air density.

How Do You know When to Change Your Mattress?

You know when you need to change your mattress-

1. If your mattress is well over 10-12 years old, really uncomfortable, or lumpy.

2. If it has permanent indentation randomly and measuring about 1.5 inches or even deeper.

3. If your mattress springs are somewhat broken and sticking out of the mattress.

These suggestions are not permanent solutions. These do not promise to fix the sagging problems completely. The one true solution would be to purchase a brand-new mattress.

Choosing A Good Mattress – What You Need to Know?

When choosing a good mattress, you need to know that:

1. A mattress is a worthy investment

2. The price of mattress may not necessarily determine its lifespan and durability

3. The warranty on a mattress is important

4. Mattresses with innerspring and coils tend to last longer

5. The quality is a very crucial factor. This can prevent it from sagging early.

6. Your sleeping position should determine your choice of soft or hard mattresses

Having the appropriate mattress is very important in fixing the mood at home. The reason is you will practically spend some time at home and in bed.  So, whether you are tossing through the night or soundly asleep depends a great deal on your choice of mattress.

We do not advise that you break a leg or an arm in a bid to acquire a superior mattress. But do remember that you are likely to use the mattress every day for a whole lot of years. It is indeed a necessary and worthy investment.

When deciding for a very cheap mattress, be sure to receive just what you paid for. Do not go having expectations of durability as the mattress will get lumpy eventually or fall apart.

A very cheap mattress is not necessarily cheap per se, because it will never be long-lasting. So, in no time at all, you will be needing a replacement that you did not bargain for.

Buying a superior quality mattress for a slightly raised price will save you all that trouble. Always remember that a cheap mattress is hardly any good and a superior mattress is hardly cheap.

Also, you might want to be careful so that you do not end up purchasing one that will sag in a little while.

Coil and hybrid mattresses tend to hold up a lot better in the course of time. They are constructed in a way that they pass as the sturdiest beds. This simply means goodbye to sag and indentations.

Look out for mattress/foams that come with innerspring support beneath and individually covered coils in the center for support.

In addition, the quality of the mattress is the most crucial factor as regards its life span or likeliness to sag. Low-density mattresses will certainly break down a lot quicker than the high-density mattresses.

Similarly, the high-gauge coil in a low-quality mattress will deteriorate rapidly, losing support.

Since they need good pressure relief for the back pain, they can look out for any mattress that offers good spine alignment. If their hips sag as a result of a mattress that is very soft, it is likely to escalate the back pains.

Side sleepers that suffer chronic back pain should purchase mattresses that come with hyper-elastic polymer material on their top exterior. This is most appropriate because it gives the mattress a comfortable feel while allowing for brilliant pressure relief.

Which Mattress is Suitable for side sleepers with chronic back pain?

The suitable mattress for side sleepers is a purple mattress. They have good coil models, with a very comfortable gel layer on the top that allows for a good cushion for some side nap.

It is necessary to have a good grasp of the important sleeping needs. Despite individual differences, side sleepers suffering chronic back pain may prefer a medium-firm foam mattress. But it should have a lot of support to assist with the back pain.

The one sure way to fix sagging mattresses is to purchase a memory foam mattress.

Thanks to some technological upgrade, a memory foam mattress is now a lot more affordable than it used to be.

Buy A Quality Memory Foam Mattress on Amazon

Memory foam mattress is more durable and supportive than the conventional traditional bed. It is made with high trailblazing techniques and super quality materials. The production inserts multiple foam layers which enables the memory foam mattress to rank top among its counterparts.

Things to Look out for when buying a memory foam mattress are:

  • Innerspring foam mattresses modeled with low-gauge springs (steel).
  • Memory mattresses modeled with medium or high-density foams.

Which Mattress Type Is More Likely to Sag?

Mattresses that are more likely to sag are:

1. Airbeds

2. Innerspring mattress

3. Hybrid mattress

4. Polyfoam

5. Latex mattress

Apart from bed quality, there are generally accepted rules determining mattress types that are more vulnerable to sagginess than the rest.

What is an Airbed?

An Airbed is a sleeping pad that is filled with air. It is made from polyvinyl chloride (PVC) or rubber. It is a flexible mattress and can be inflated and deflated when not in use.

These are classed among the expensive options. They employ air chambers that have foam support layering. Due to the resilience in the air chambers, air beds are less prone to sagginess.

Latex Mattresses

These have become quite popular, thanks to their comfortability. They support, bounce, and conform nicely to the body. They will not sag easily, especially in their early years of use.

Hybrid Mattresses

They are combinations of the memory, latex mattress, and the innerspring mattress. These combinations make up really comfortable top exterior layers, resting firmly on some innerspring support. If high-density and low-gauge spring materials are used, the lifespan of the hybrid foam will be extended.

Poly Foam

What is Poly foam?

Polyfoam is a soft foam that contains bubbles and provides comfort in a memory foam mattress. It is also referred to as Polyurethane foam. It is majorly used to pad up a mattress.

The sagginess of the polyfoam is determined by the softness and density of the mattress.

Innerspring Mattresses

These almost always lose their coil strength, which is mostly the reason for not being such a popular option anymore. But there are some of these types of beds that are made with very high-quality spring materials (steel springs).

What to Look for When Choosing Mattress for A Plus-Sized Person

When choosing a mattress for a plus-sized person look for mattresses that are firm and can offer toughness.

Here are some hints:

1. Ensure the mattress/ bed of choice provides a comfortable soft hug without the sinking feeling.

2. The mattress should be covered in a super firm layering of foam. This will ensure the mattress does not collapse if bodyweight moves to the edges.

3. Check to be sure it has active support with a minimum of 1600 independently covered coils. These should thrust back the body weight and reply to changes in sleeping positions

4. Be sure the layers of the mattress will not slide out of its original placement.

5. Be sure the bed foundation is made durable. It should be about 16-17, 2.5 inches slats with a double center rail that will be able to support six times the regular body weight.

6. Go for mattress/foams that are designed with materials that offer breathable and cooling comfort to help the dispersion of body heat

7. Find mattresses that have a sufficient thickness that is, give or take, 10 -15 inches. This will accommodate very deep compression without giving way too soon

8. For any bed or mattress, you choose, check its weight limit with the manufacturer.

For people that weigh past 150-200 pounds, there should be certain special features to look for when purchasing a mattress. This is so that they can have all the comfort and support they need.

Bodyweight is one of the most considered factors that aid the sudden sagginess of a mattress. A mattress used by a heavy or plus-sized person is likely to sag a lot faster unlike when it is used by someone of medium weight.

Being somewhat larger than the regular average weight, your choice of a mattress/bed should be narrowed down using some criteria.

A heavier person should always consider a thicker mattress. This will provide adequate support for the spine in a neutral position notwithstanding the sleeping position, be it latex, foam, or innerspring.

The more you weigh, the more you should consider going for a firmer mattress than the other lot. For instance, a mattress graded 8 on firmness may very much feel like a 7 for a plus-sized user.

Is It Alright to Put Your Mattress on the Floor?

It is alright to put your mattress on the floor. It is cost-effective as well as weather friendly during hot seasons. This is because it aids the circulation of airflow, as a result, the mattress remains cool.

It is usually considered a temporary option until the actual accessories arrive. However, this arrangement may linger due to some unplanned circumstances.

You could be wondering, “is it really harmful leaving the mattress on the floor?” and “how long exactly should it be left on that placement?”

Why Raise the Bed/Mattress from the Floor?

You can raise your bed or mattress from the floor because:

1. It provides warmth

2. It prevents dirt from touching the mattress

3. It prevents insects and harmful rodents from attacking the mattress

4. It eliminates the risk of molds growing under the mattress

5. It helps the joints and bones to relax

Sleeping in raised beds started out around the medieval and Victorian times. It was a form of distinction among the wealthy and the peasants who slept on hay floor beds which were usually riddled with bedbugs.

With time and development, raised bedposts became more commonplace in the society and among all the economic levels.

One of the major reasons for raising the bed from off the floor is for warmth. This is as a result of the warm air that rises higher while you are in the room. The cold air that pours in from beneath the doors is shut out by elevating the bed a little off the floor.

Also, it is a general understanding that the floor gets dirty quite easily. This dirt gets on the mattress, leaving it moist and dirty if it is left on the floor.

Placing the mattress on the floor makes it very accessible to insects and harmful rodents.

After a while, it can often be hard on the joints and difficult to get up because the mattress is too low with no elevation.

As a result of little or no airflow, moisture is trapped beneath the mattress. This can result in mold activities that are a great health risk and ruin the mattress as well. It is best to lean the mattress on the wall or sun dry it occasionally.

In conclusion, we hope that this article will help you a great deal in reinforcing your sagging mattress. The information provided will also help in preventing sagginess as well as in choosing a suitable mattress.
