A worn mattress tends to sag in the centre. When you lie down, you’ll feel dents in your hip and back areas.
You may also wake up with lower back pain or stiff muscles. It is likely that your mattress no longer provides enough support to keep your spine aligned. A good mattress should help maintain healthy alignment of the spine by keeping it in a relatively straight, natural line. When your mattress ages, the material will sag and you’ll sink in more deeply, which misaligns your spine. If you’re feeling this so-called hammock effect, then it’s time to change your mattress to avoid pains and sleepless nights.
Another sign of a bad mattress is visible distortion. To find out if your mattress has lost its shape, you can use a measuring tape to check for visible sagging areas.
Older mattresses also cause more severe allergies. Dust, dust mites, pollen, and mould accumulate in your mattress over the years, and this is more pronounced in older mattresses. As a result, you may experience itchy eyes, rashes, and even difficulty breathing. Even if you have a mattress that’s specifically designed for allergy sufferers, you’ll risk reacting if the mattress is too old.
