If you have excellent lifestyle habits but wake up with back tension only at home, your mattress (worn out or unsuitable) is likely the cause. Switching to a mattress adapted to your body and sleeping positions is essential to eliminate this discomfort and optimize your recovery.

Science supports the idea that an unsuitable or worn-out mattress can disrupt nocturnal posture and cause morning stiffness. A 2021 systematic review published in the *Journal of Orthopaedics and Traumatology* confirms that a medium-firm mattress promotes proper body alignment and restorative sleep. Furthermore, a benchmark randomized clinical trial published in *The Lancet* demonstrates that a medium-firm mattress significantly reduces morning back discomfort compared to a very firm model. A 2023 observational study conducted by university researchers also shows that prolonged mattress use (often more than 8 to 10 years) is correlated with an increase in physical discomfort. Nevertheless, presenting the mattress as the sole culprit for back pain is reductive, as these morning tensions are multifactorial and closely linked to daily stress or general fatigue. Finally, while adjusting sleep surfaces to body type is a logical ergonomic approach, the effectiveness of online questionnaires or quizzes in scientifically identifying the ideal model remains to be proven.
