Mattresses sag because they are not well supported by their internal structures or because the support from beneath is insufficient.
The mattress may sag from its own weight if you are not using a box spring.
The mattress foundation you currently have is old and weak, so it sags under your weight. Over time, the weight on the mattress causes the interior to weaken, leading to soft spots and sagging.
How To Fix A Sagging Mattress With Plywood
In order to detect sag, you’ll need a ruler or rod to measure the level of the mattress. If you notice a gap, you’ll know that the mattress is sagging. You’ll also know where it is, so you can take action.
1. Take Measurements
Measure the bed base and see if you’ve got a plywood sheet that fits its dimensions. If not, order one from your home improvement center and get it cut to size. If you can’t find a sheet that’s big enough, you can order a sheet from the same store and cut it down.
2. Place the Plywood
Next you need to lift your mattress, so that you can see the frame or box spring.You can use a sheet to help you lift the mattress to get to the box spring. Make sure the sheet fits neatly across the width of the bed. If you’re using planks, make sure they’re evenly spaced.
3. Test It Out
Lay the mattress on the plywood and test comfort and movement. If you do not hear bending or creaking, the planks are in the correct position. Also, the mattress should no longer be sagging.
How Thick Should The Plywood Be?
One common error people make using the plywood fix is believing it’s true that every sheet of plywood will be acceptable. This isn’t the case.
A thin piece of plywood is not sufficient to support the weight of someone sleeping on the mattress and it will not be enough to withstand the normal movements.
To protect yourself the plywood should at least 3/4 inch thick.
A thickness of 3/4 inches is sufficient for those who are small and young. If there is multiple people in your bed, try to find a piece of plywood that’s at the very least 1 inch thick.
Should You Sand Down Your Plywood?
In reality, it’s not required but it’s an ideal idea.
Sanding down your plywood will assist in stopping your mattress from getting caught in sharp wood.
If you’re able to do this, you don’t have to spend a lot of time doing it.
A little sanding could do a lot of great things for the security of your mattress.
Drawbacks of Plywood
We all know that plywood under the mattress is not a good idea. It will bring extreme problems instead of solving the sagging problem.
Mildew grows on plywood especially if you live in a humid area.
The plywood doesn’t absorb the moisture, which makes the mattress get soggy and become less comfortable.
Eventually you’ll need to replace the mattress.
Alternatives to Plywood
A mattress topper provides extra cushioning and adjusts firmness throughout the bed.
Mattress toppers come in different types.
The most common are the ones made from memory foam, gel foam, or latex.
However, are favorite is bamboo mattress toppers.
We recommend you buy at least a 4-inch thick topper.
These are specially designed to fit under the mattress and are better for innerspring mattresses and hybrid mattresses. For a sagging mattress, you may find these more effective than a mattress topper.
Should You Use Plywood As A Preventative Measure?
Most people tend to think of “plywood” as a preventative step that should be taken when you purchase an item like a mattress.
It’s actually a risky option in the event that your mattress isn’t sagging.
In reality, it’s very bad for your mattress in the long haul.
Here are some reasons why that is:
- Plywood doesn’t let your mattress breathe as it should: This means that you may end up storing excessive moisture inside your mattress. This could result in the growth of mold and bacterial growth and other problems.
- It will shorten the lifespan of your mattress: With movement on your bed every day you can anticipate the fibers to get caught and catch on the plywood. In the end, plywood isn’t exactly the most smooth material around. This can result in your mattress having tiny tears that could affect the overall health of your mattress.
- If you’re currently keeping your mattress housed in a case because of bed bug infestation, it is important to recognize that the plywood may tear the case: One splinter is all it takes to make a hole in the mattress case that is made for bed bugs. When you consider the the cost of a bed bug exterminator, it’s best that you don’t risk tearing the case.
What Is The Best Way To Fix A Sagging Mattress?
The trick with plywood is great. However, if you don’t want to buy a piece plywood, there are alternatives. You could go the mattress topper route.Or, you can flip the mattress over, and then prop a pillow in the area it is sagging.
However it’s still recommended to look over your bed’s mattress and shape, if you wish to select the most suitable solution.
If you’re trying to determine the reason for the sagging, you need to inspect the frame of your bed and the slats.
If the frame appears damaged, repair it before you purchase an entirely new mattress.
This will help ensure that you will get the maximum longevity for your new frame and will also help prevent the possibility of further damage to your mattress.
Frequently Asked Questions
How long should you expect a mattress to last before it sags?
Although the sagging of mattresses is a frequent problem, don’t anticipate it to be a problem that will occur quickly. Modern technology has increased the life span of mattresses more than ever. A mattress can last between 7 and 10 years with no evidence of sagging.
Are there any types of mattresses that don’t sag?
If you’re trying to prevent the risk of sagging, the ideal choice for your mattress purchase will be a latex foam or memory foam mattress. The majority of foam mattresses are less prone to the chance of sagging, and last up to 15 years without showing any signs of sagging.
What kinds of mattresses are the most likely to sag?
Every mattress will eventually require replacement from sagging. That includes foam mattresses if kept to sit for too long. For sagging issues, the most prone types of mattresses are box spring mattresses. Box springs typically have the lowest lifespan, with the highest probability of stretching, and are the most susceptible to crack due to the use of springs.
