Why Use A Mattress Topper?

A mattress topper is a removable 3cm-6cm layer added on a mattress for additional support and comfort. Mattress toppers are the same size as the mattress, so at a glance, it is easy to assume that it is part of the mattress. 


To get the perfect mattress topper size and thickness, you need first to determine your mattress size. You can compare the measurements or buy one according to your bed size. When looking at the thickness, consider your needs. The thicker mattress topper is firmer than a thin one.


Once you have the size and thickness sorted, you only need to determine the best material, and you will have the perfect mattress topper Singapore. 


How To Choose Mattress Topper Thickness


You need to have several things in mind before choosing a mattress topper based on how thick it is. Analyze why you need a mattress topper, the condition of your mattress, and how much are you willing to spend?


Before choosing a mattress topper, you first need to determine if you want a softer or firmer one. If you want to change the firmness from soft to firm, get a mattress topper that is 2 -5 inches thick. If you improve mattress durability, get a topper that is less than 2inches thick. 


Mattress toppers Singapore have multiple functions. Although its primary role is to improve your comfort while sleeping, a mattress topper can reduce the pressure on the mattress, which will boost its durability. 


Mattress toppers can also extend the life of an old mattress, especially if you do not have plans to replace the mattress yet. This could buy you another three or four years of comfort. 


Importance Of The Material When Choosing Mattress Toppers. 


Many people only look at size and thickness when buying mattress toppers. However, the materials are just as important because they affect the softness and fitness of the mattress topper Singapore. 


For example, a mattress topper made of latex is usually firmer and thicker than feathers.

If your mattress is more than 2 inches thick, it will change the feel of your mattress. It will be firmer, so if your mattress was already firmer, expect this combination to be worse if what you needed was a softer bed. Instead, you should get a mattress topper that will give you what you lack in your mattress. 


If you have a worn-out mattress, you will need a thick mattress topper to provide more cushioning and support. Thin mattress toppers are great for mattresses that already offer great support. Look for a reputable mattress topper supplier in Singapore for quality mattress toppers for your bedroom.
