This is because the mattress in your bedroom is used regularly; therefore, it starts sagging or de-shaping from the sleeping side you use. Hence, you can say that the longer and more frequently your mattress will hold you, the more it will start to sag, as the materials inside it get compressed.


Proper care can increase the life of your mattress. Rotate the mattress regularly, clean it as per the manufacturer’s instructions, and use a waterproof cover on it to protect it from spilled food or drinks, stains, and smell caused by the sweating of the hot sleeper.
