If this isn't enough of a reason to update your mattress....................
After 10 years, a mattress will likely contain a significant, but not double, amount of dust mites and their waste products. A mattress can accumulate 100,000 to 10 million dust mites, feeding on dead skin cells, which can exacerbate allergies and affect sleep quality. While the weight of the mattress will increase due to this buildup, the claim that it doubles in weight is a myth. Replacing your mattress every 7-10 years is recommended for hygiene and to maintain comfort.
