The hidden risks of sleeping on an old mattress: why it's time to replace yours

Updated: Oct 11, 2023

It's easy to underestimate the importance of a good mattress for a good night's sleep. However, sleeping on a mattress that is too old can cause significant health problems, such as back pain, muscle stiffness and even allergies. Mattresses have a limited lifespan, and it's important to replace them regularly to ensure restful sleep.

According to a study conducted by the American Academy of Sleep Medicine, a mattress should be replaced every 7 to 8 years. Beyond this period, it gradually loses its support and comfort properties, which can cause back pain and muscle stiffness. People who already suffer from chronic back pain should consider replacing their mattress more frequently, every 3-5 years.


The MPILI 12 mattress is a wise choice to guarantee quality sleep and avoid health problems linked to a worn mattress. Indeed, with its design in alternating layers, each layer undergoes less pressure, which makes it possible to prolong the life of the mattress and to offer constant and lasting comfort for a restful sleep.


Apart from musculoskeletal problems, sleeping on a mattress that is too old can also cause respiratory problems. Dust mites, molds and bacteria grow easily in mattress stuffing materials, especially if they are damp or poorly ventilated. These microorganisms can cause allergies and respiratory infections, including asthma.
