How To Keep Your Mattress Topper Fresh

A bed that’s not taken care of can turn your bedroom into a haven for allergens and bacteria. When it comes to the mattress topper attached to your mattress, you need to keep it clean regularly.

When it comes to replacing your mattress topper, you need to determine first if it’s because of aging or dirt and stains. If you suspect there are bedbugs, mold or are noticing other signs of poor hygiene throughout the house, then it’s time to replace the mattress as well as its cover.

Wear And Tear

Like any other bedding, over time, toppers lose their aesthetics and their helpful function. It doesn’t matter if your mattress is clean; it needs to be taken care of every time you lie down on it. Therefore, the best way to find out if your topper’s lifespan is running out is by looking at its appearance. If you notice that the edges are beginning to fray and the seams are starting to look worn out, it’s time for a replacement.

Thinned Out Material

Thinning out is most common on toppers made of cotton. As you have never washed it and often use it, it gradually loses its puffy look and loses its elasticity over time. 

Lasting Odor

The most common complaint of toppers is their smell. As a natural material, cotton toppers have enough oils that can be easily absorbed by your body. Eventually, they can start to give off a distinct smell which is often considered a sign of poor hygiene.

Mold Growth

Toppers made from synthetic materials can also fail due to mold growth over time. This problem is more common in humid environments with no ventilation system or air circulation systems in your home, especially if you live in a coastal area.

For non-organic layers, always consult the product’s owner’s manual for specific instructions on cleaning them.
