1. The common causes of mattress sinking and identification methods


Mattress sinking is a common mattress problem and a common nuisance faced by people. Sinking mattresses usually lead to sleep discomfort, and in the long run, it may also cause some adverse effects on the human body, such as muscle aches and pains, and reduced sleep quality.


1.1 Common causes of mattress sinking

Sinking mattress is actually a part of the mattress that has lost its original elasticity and support, which is manifested as a depression in a certain part of the mattress. This phenomenon may be caused by the following reasons:


  • Prolonged use and aging: The mattress will inevitably be subjected to a certain amount of pressure during use, so the springs or fillings inside the mattress will gradually lose their elasticity over time. This situation is more obvious when the mattress is used for a longer period of time.


  • Uneven pressure distribution: If pressure is applied to one part of the mattress for a long period of time, the mattress in this part may sink. For example, always sleeping on one side of the bed, or sitting on the mattress a lot to watch TV or play with the cell phone, etc., may cause the mattress to age prematurely in the pressurized area.


  • Quality problem: If the manufacturing quality of the mattress is not up to standard, such as poor quality of fillings, low quality of springs, etc., it is also easy to cause the mattress to sink.


1.2 Recognition method of mattress sinking

Sinking mattresses have a great impact on our daily life and sleep quality, so it is very important to recognize whether there is a sinking mattress problem in time. The following are some common ways to recognize a sinking mattress:


  • Observe the surface of the mattress: if the mattress is sinking, there will usually be obvious depressions or protrusions on the surface of the mattress. You can start by checking visually to see if the mattress surface is flat.


  • Feeling comfort: Lie on the mattress and feel if your body can be evenly distributed on the mattress. If you feel that one part of your body is significantly lower than the rest, or if you feel uncomfortable while lying on the bed, then the mattress may have a sinking problem.


  • Feel test: you can also use your hands to press the mattress, if the mattress does not immediately return to its original shape after pressing down, or obviously feel that a certain area is softer than other areas, then the mattress is likely to have a sinking problem.


2. DIY Methods to Fix Mattress Sinking by Yourself


When we notice a sinking mattress problem, trying some DIY fixes may be the quickest and most cost-effective solution. For minor sinking problems, these methods can often achieve immediate results. Next I will introduce you to some common and effective DIY fix strategies.


1. Use mattress shims

A mattress shim is a common DIY repair tool that is usually made of high-density foam or rubber and is designed to provide extra support. You can place a mattress shim in the sunken area between the mattress and the bed frame to elevate the area and bring the surface of the mattress back to level. When choosing a mattress shim, always make sure that it is the right size for your mattress and that the material is strong enough to provide lasting support.


2. Flip and rotate your mattress regularly

A major cause of mattress sagging is pressure in the same position for a long period of time, causing the fillings or springs inside the mattress to lose their elasticity. Regularly flipping and rotating your mattress will allow for more even wear and prolong its life. Generally, we recommend flipping the mattress up and down every three months and rotating the mattress head to tail every six months.


3. Install a mattress support

A mattress support is another effective DIY fix that provides extra support for the mattress and prevents it from sinking in the center. Installing a mattress support usually requires some manual skills, and you can find detailed installation guides online.


These are three common DIY mattress fixes. When trying these methods, always remember that safety comes first. If you find that you have a serious problem with your mattress sinking or have tried DIY methods with poor results, then it is best to seek professional mattress repair services.


3.Seek professional help: when and how to find professional mattress repair services


While self-repair is a possible solution, sometimes we are faced with mattress sinking problems that may be beyond our skill set and capabilities. For example, if the sinking area of the mattress is very large, or if the springs or fillings inside the mattress have been severely damaged, a DIY fix may not provide an adequate solution in this case. Additionally, if you've tried DIY methods and the condition of your mattress still hasn't improved, or if you're unsure how to properly perform mattress repair, these are all reasons to seek professional help.


One of the distinct advantages of seeking professional mattress repair services is that they have the specialized techniques and tools to effectively deal with all kinds of mattress problems, thus prolonging the life of your mattress and safeguarding the quality of your sleep. Their professionals are expertly trained to accurately identify mattress problems and provide solutions accordingly.


So, how do you find and choose a professional mattress repair service? Here are some tips for finding and choosing a mattress repair service:


  1. Online search and reviews:you can search for mattress repair services online to see what they offer, how much they cost, and what their customers say about them. Very often, you can get an idea of the quality and reliability of this service through customer feedback.


  1. Refer to friends' and family's recommendation:If your friends or family members have used a certain mattress repair service before and expressed their satisfaction with it, then you can consider using the service recommended by them. Their personal experience will give you more direct feedback and confidence.


  1. Communicate with the service provider:Before choosing a mattress repair service, you should communicate with the service provider in detail to understand their repair process, the tools and materials they use, and their guarantee for the repair results. If they can provide you with a detailed repair plan, it means they have in-depth knowledge and experience in mattress repair.


  1. Examine the professional qualifications of the service provider: A professional mattress repair service should have relevant qualification certificates. You can ask them to provide relevant certificates or licenses to ensure that their services are professional and legitimate.

4. Effective Strategies to Prevent Mattress Sinkage


Avoiding mattress sinking first requires us to understand and master some effective prevention strategies. The following are some of the main strategies to prevent mattress sinking:


1. Turn and rotate the mattress regularly

Regularly flipping and rotating your mattress is the most basic way to prevent mattress sinking. By flipping and rotating, you can evenly distribute the wear and tear on the mattress, preventing excessive wear and tear on one part of the mattress that can lead to sinking. For a double-sided mattress, you should flip it every 3-6 months. For a single-sided mattress, you can rotate it every 3-6 months.


2. Avoid excessive pressure

Avoid stacking heavy objects on your mattress for long periods of time or engaging in over-pressurized activities. These behaviors can lead to excessive pressure on the internal structure of the mattress, which can accelerate wear and tear and sinking of the mattress.


3. Use a mattress protector

A mattress protector protects the mattress from stains and liquids, as well as distributing the pressure from your body to prevent the mattress from sinking at a point of excessive pressure. Choosing a good quality mattress protector will extend the life of your mattress as well as improve your sleeping comfort.


4. Buy a good quality mattress

Choosing a high quality mattress is another key factor in preventing your mattress from sinking. High-quality mattresses are usually made with premium materials and advanced manufacturing techniques for better durability and support. While the initial investment in a high-quality mattress may be larger, its longer lifespan and better sleeping experience can be very cost-effective in the long run.


5. Choose a mattress based on your weight

It is also important to choose a mattress based on your weight. Generally, heavier people need a firmer mattress to provide adequate support. If you weigh less, a soft mattress may be a better choice. The firmness of the mattress should keep your spine in its natural curve while you sleep.


5. A Practical Guide to Buying a New Mattress

When you have a mattress sinking problem that can't be fixed, buying a new mattress may be the best solution. So what are some key factors to consider when buying a new mattress?


1. mattress type:

The type of mattress affects its comfort and durability. There are four main types of mattresses on the market today: spring mattresses, memory foam mattresses, latex mattresses, and waterbeds. Spring mattresses provide balanced support and good ventilation and are the most common type of mattress. Memory foam mattresses adjust to the shape of your body and provide excellent pressure relief. Latex mattresses, on the other hand, have natural anti-bacterial and anti-mite properties and have a long lifespan. Waterbeds, on the other hand, are favored by some for their unique feel and temperature regulation.


2. Mattress firmness:

The firmness of the mattress should be chosen according to your personal preferences and physical needs. A mattress with higher firmness can provide better support and help maintain the normal curve of the spine, which is suitable for people who have discomfort in the lower back. A mattress with lower firmness, on the other hand, fits the body's curves better and is suitable for side sleepers or people with back pain.


3. Mattress size:

Mattress size should be chosen based on your bed frame size and personal needs. Common mattress sizes are single, double, queen and super king. If you are using it alone, a single or double bed will suffice. If you are using it with a partner or you like to have a lot of space to move around, then a queen or super king bed would be a better choice.


4. Mattress brand:

It is very important to choose a mattress brand that is reliable in terms of quality and service. You can judge the quality of a brand through online reviews, word of mouth and the brand's after-sales service.


If your mattress is beyond repair or it is time to replace it, then buying a new mattress is the best option. There are many factors to consider when buying a new mattress, such as the type, size, firmness and price of the mattress, as well as your sleeping habits and physical condition.


When you choose a mattress from Suilong, you don't need to worry about these issues.

5. budget:

Finally, you need to choose a mattress based on your budget. The price of mattresses varies greatly, ranging from a few hundred dollars to tens of thousands of dollars. Generally, good quality mattresses will cost more, but they are also usually more comfortable and durable.


Buying a mattress is an important investment because it directly affects the quality of our sleep and our health. Therefore, when purchasing a new mattress, make sure you consider all of these factors and choose a mattress that is best for you.


6. Alternative solutions to the sinking problem: mattress padding and bed frames

Mattress padding and bed frames play an important role in solving the problem of sinking mattresses. If we examine them carefully, we can see that their roles are multifaceted and complementary.


A mattress topper, or mattress topper, is a layer that is placed on top of the mattress to provide us with extra comfort and support. It provides extra protection for the mattress and allows for a more even distribution of pressure, thus slowing down wear and tear and preventing the mattress from sinking too quickly. There are a wide variety of materials for mattress padding, including memory foam, innerspring mattress, down, etc. You can choose the right mattress padding according to your personal preference and needs.


The role of the bed frame should not be overlooked either. The bed frame is the support structure of the mattress. A high-quality and well-constructed bed frame can effectively support the mattress and prevent it from sinking excessively in the middle part. In addition, the design of the bed frame can also ensure the ventilation of the mattress, helping to dissipate the heat and moisture absorbed by the mattress, and prolonging the life of the mattress.


Therefore, when we find the problem of mattress sinking, besides repairing or replacing the mattress itself, we should also consider using mattress padding and replacing the bed frame to solve the problem. When purchasing a mattress topper, consider the thickness, material and comfort of the topper, as well as how well it fits your mattress.


When choosing a bed frame, consider its material, construction, size and durability, as well as how well it works with your mattress and bedroom space. Through proper selection and use, mattress padding and bed frames can provide us with a better sleeping experience and the best sleep position while effectively solving the problem of mattress sinking.


7. The correct care and maintenance of the mattress


The care and maintenance of a mattress is the key to ensuring its longevity and sleep quality. A good care and maintenance habits can effectively prevent the mattress from sinking, deformation or other damage problems, but also help to enhance the sleep experience.


  • Cleaning and Care: Regular cleaning of the mattress is a basic step in mattress maintenance. It is recommended that you use a vacuum cleaner to gently sweep the surface of the mattress every two weeks to one month to remove dust, dander and other tiny particles to prevent them from penetrating into the mattress. If the mattress is inadvertently contaminated with liquid, the liquid should be immediately soaked up with a clean cloth, then gently wiped with a mild detergent and cold water, and finally allowed to dry naturally.


  • Preventing Excessive Pressure: Although mattresses are designed to withstand pressure, prolonged or excessive pressure may still cause the mattress to deform or sink. Try to avoid jumping or placing heavy objects on the mattress, especially for long periods of time. If you often do activities such as reading or working on the bed, you should also change the position frequently to prevent a part of the mattress from bearing too much pressure.


  • Regular flipping and rotating: A surface or a part of the mattress under pressure for a long time will accelerate wear and tear, leading to deformation or sinking of the mattress. Therefore, it is recommended to flip or rotate the mattress every 3 to 6 months to allow pressure to be distributed more evenly across all parts of the mattress. Note that some mattresses are designed to be used on one side, in which case you only need to rotate the mattress.


  • Proper base: The base or frame of the mattress also has a big impact on the longevity and performance of the mattress. The base should be firm, smooth and provide adequate support to avoid the mattress sinking in the center. If a bedpan is used, the gap should not be too large to prevent the mattress material from seeping into the gap and causing deformation.


  • Avoid long-term unused: If the mattress has not been used for a long time, it is recommended that it be ventilated on a regular basis to avoid dampness causing the mattress to become moldy. At the same time, the state of the mattress should also be checked regularly to find and solve the problem in time.


At this moment, you are armed with various strategies and tips on how to fix a sinking mattress, and I'm confident that this information will help you find the best solution to revitalize your mattress and give you a comfortable sleep experience. Remember, a good mattress is not only a support for your body, but also for your physical and mental health.

Q: Can you fix a mattress that sinks in the middle?

A: Yes, you can fix a mattress that sinks in the middle. Methods include using mattress toppers, plywood support, mattress helper, or inflatable mattress pads to provide extra support. However, if the sagging is severe and these methods don't provide relief, it may be time to consider a new mattress.


Q: How do you firm up a sinking mattress?

A: You can firm up a sinking mattress by using a mattress topper, especially a firm memory foam topper or a latex topper. Another method is to place a plywood board between the mattress and the bed base for added support. Regularly rotating or flipping the mattress can also help maintain its firmness.


Q: Why does my mattress keep sinking?

A: Mattresses may start to sink due to a number of reasons such as prolonged usage, insufficient support from the bed base, or the quality of the mattress itself. Memory foam mattresses, in particular, can start to sink over time as the foam loses its elasticity.


Q: How much sag is acceptable in a mattress?

A: Most manufacturers consider a sagging depth of 1.5 inches and above as a threshold for warranty claims. That being said, even minor sagging can cause discomfort and affect your sleep quality. So, if you start to notice any sagging, it might be worth considering either fixing or replacing your mattress.


Q: Can a sagging mattress cause back problems?

A: Yes, a sagging mattress can cause back problems. A mattress that sags fails to provide adequate support to the spine, leading to poor sleeping posture, muscle strain, and misalignment of the spine. Over time, this can result in chronic back pain and other health issues.
