Invest in a Mattress Topper

A topper though not an absolute solution is very close. It is also an inexpensive alternative that can delay buying a mattress by another few years and give you a new feel and more comfort.

Why do mattresses get heavy?

Mattresses acquire weight as they absorb dead skin and dust mites that feed on dead skin, oil, and moisture. Dust mites spend a third of their life in beds.

According to Ohio State University, an average old mattress has 100,000 to 10 million mites. Dead mites and their excretions may weigh 10% of a two-year-old cushion. Mites enjoy warm, damp environments, such as sleeping mattresses. Dead skin is one of their favorite meals, and we lose approximately a quarter of an ounce of it every week, some of it flaking into our mattresses.

With all those mites and dead skin, the mattress is likely to be heavier than fresh.
