A must-read before buying a new mattress! How to choose a mattress topper to refurbish your mattress

When you feel that your mattress is starting to wear out, the first thing you think of is to buy a new one. However, replacing a mattress is not something you can do casually. So, another option we recommend is a mattress topper .

A mattress topper can improve the comfort of your current mattress at a much lower cost than buying a new one. If you're thinking about replacing your mattress, be sure to consider a topper as one of your options.

This time, we will introduce what you should consider when thinking about replacing your mattress, as well as mattress toppers and mattresses that are easy to replace, so please read to the end.



When to buy a new mattress

If any of the following points apply to you, you may need to buy a new mattress. Consider buying a new mattress rather than a mattress topper.

▼ Mattress replacement check

  • I've been using it for over 10 years
  • I no longer feel fully rested even after a night's sleep
  • Your weight has changed significantly since you purchased your current mattress
  • The mattress creaks every time you turn over in bed
  • There is noticeable sagging or denting in the lying area
  • Suffering from dust and allergies

If the above "Mattress Replacement Checklist" does not apply to you and you want to easily improve your sleeping comfort, we recommend using a mattress topper.

About Mattress Toppers


Learn more about mattress toppers.

Generally, mattress toppers are used to adjust the comfort of your mattress. Whether you want a softer or firmer bed, the right topper can help.

Typically, a mattress topper is placed on top of the mattress and then a sheet is placed on top of it.

They range in thickness from about 2.5 to 12.5 cm, and although the feel and price vary depending on the material, they are typically more affordable than the mattress itself. A good quality topper can last for about five years (about half the lifespan of a typical mattress).

It's important to choose carefully

Ultimately, a mattress topper can't magically restore an old or worn-out mattress, and if your mattress is showing signs of wear, it might be time to consider replacing it. However, a mattress topper can dramatically change the way you sleep.

It's important to carefully consider whether a mattress topper can improve the situation or whether a new mattress is needed.

Please refer to the "Mattress Replacement Check" above to make the best choice.
