Existing studies focus primarily on ergonomic aspects, such as pressure relief and spinal support, yet lack conclusive evidence linking these features to improved sleep quality.Objective and Methods: This study aimed to evaluate the effects of mattress firmness on sleep quality. Twelve participants with a 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.Results: Our findings indicate 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.Conclusion: This study provides evidence that mattress firmness significantly influences sleep quality, with medium firmness offering optimal outcomes for individuals with a moderate BMI. The findings contribute to the development of scientifically informed mattress designs, including smart mattresses aimed at improving sleep quality.Keywords: mattress firmness, sleep quality, sleep architecture, EEG characters, PVT |
