After some time, your cushion bed will have uneven support that will hinder your comfortable sleep.


Cause #2. Quality of material

Yes! Wear-and-tear is normal for your bed.

However, the duration of your pad depends on the quality of the materials used.

That is why it is important to consider quality when buying a mattress.

The longevity of it will serve as your investment.


Cause #3. Wrong mattress for your body

Quality is not the only thing that you need to consider when buying a mattress.

You should also evaluate your body type, weight, structure, and sleeping position.

Buying the wrong material for your body will tend to sag early.

Always think about it, evaluate and consider everything that matters before getting the right one for you.

The only way to fix it is to send it to the manufacturer for repair. But first, you should know the warranty coverage of your mattress.

5 Easy Steps To Measure Mattress Sag

Are you wondering how to measure mattress sag?

Here are five easy steps to measure the sag in your mattress:

Things you need:

  • String
  • Masking tape or Painter’s tape
  • Measuring tape (You can use any type, but it is recommended to use a stiff type of measuring device such as steel measuring tape)


Step #1. Remove all bedding

Remember, accuracy is the number one rule in measuring the sag.

Thus, remove everything from your mattress, and that includes bedsheets, pads, and foam toppers.


Step #2. Smoothen your mattress

To avoid inaccuracy, you need to smooth the top of your mattress.

Get rid of every wrinkle in the fabric of your mattress.


Step #3. Prepare to measure

First, you need to lay the string across the width of your mattress.

Make sure that it reaches from one side to the opposite side.

Then, it should cross over the deepest part of depression.

Lastly, secure one end of the string to the edge of the mattress using masking tape or painter’s tape.

You must consider this type of tape because other types might leave a sticky residue on the fabric when removed.


Step #4. Secure the ends

Now that you have the string over the depression of your mattress, it is time to get your measuring tape.

Start by pulling the end of the string on the other side of the bed until it is fully stretched.

Secure the ends of the string with a strip of tape.

The strings are now on top of your mattress. However, it still hasn’t measured the sagging part.


Step #5. Measure the dip and get the results

If you are using a stiff measuring device, do not put too much pressure on the mattress because the more pressure you’ll apply, the deeper the mattress will be.

When measuring the dip, start by putting the tip of the measuring device on the mattress.

Then, spot the lowest point of the dip and measure it up to the end of the string. Note that you have to hold the measuring device by 90 degrees upward.

Lastly, the result you’ll get from the measurement will tell you how deep the sag is in your mattress.
