Science shows that the right mattress firmness is critical to better sleep. For those with a moderate BMI, the 'Goldilocks' zone of medium firmness delivers the ideal balance of support and comfort. At RUCAS, we don't just make mattresses; we design intelligent sleep systems. By leveraging these scientific findings, we create adaptive smart mattresses tailored for diverse populations, ensuring everyone wakes up refreshed.
According to research, the hardness of a mattress has a close relationship with sleep quality. This study involved 12 participants with moderate body mass index (BMI) were tested across three levels of mattress firmness: soft (32.6 HA), medium (64.6 HA), and firm (83.8 HA). Sleep architecture and neurophysiological activity were assessed using polysomnography (PSG), with EEG-derived features, including power spectral characteristics, sleep spindle activity, and slow-wave parameters, further analyzed.
The research results show that a medium-firm mattress provides better sleep quality, reflected in a narrower range (Range=xmax-xmin) of sleep duration, efficiency, and sleep latency, as well as increased sleep spindle activity. A repeated-measures ANOVA revealed a significant effect of mattress type on sleep latency (p < 0.05, partial η²=0.26), with sleep latency being longer on the soft mattress (12.42 ± 1.94 min) than the medium mattress (7.71 ± 1.31 min, p < 0.05). Another repeated-measures ANOVA showed significant differences in stage transitions (p < 0.05, partial η²=0.32), with more transitions on the soft mattress (29.17 ± 2.35) compared to the firm mattress (21.75 ± 2.13, p < 0.05). The firm mattress yielded mixed results, suggesting suitability for some individuals but not universally. Post-sleep vigilance differences were not statistically significant.

According to research, there is evidence indicating that mattress firmness has a significant impact on sleep quality, with medium firmness proving to be optimal for individuals with a moderate Body Mass Index (BMI). Therefore, based on these scientific findings, we at RUCAS Mattress design our mattresses with the aim of producing smart mattresses suitable for various populations, enhancing their sleep quality.
