- “some authors recommended mattresses with an air overlay system to reduce pain, while others showed that variation of temperature can promote sleep”
- One study used a”foam-encased Bonnell spring unit, densified fibre pad, super-soft foam, damask cover, semi-flex foundation, slick fibred [14].At the end of the experimental phase at day 28, a back pain decrease of approximately 48% and an improvement of sleep quality of 55% were reported; such improvement correlated with a significant decrease in stress levels.”
