“…Our findings indicate that after adjusting for other factors, only mean pressure showed a negative correlation with buttocks and thigh comfort, which is consistent with the results of Zhang et al, who found that in the process of using smart beddings, the comfort of core body parts is related to mean pressure [39]. However, we also found that body pressure distribution and comfort did not always change in tandem, which is inconsistent with previous studies [25,30,40,41]. For example, Stanglmeier et al [40] evaluated the biomechanical quality of sleeping postures based on the effect of the seat pan and backrest's angles on the interface pressure distribution.…”

“…Their findings showed that a decrease in the weighted average pressure level positively affected comfort and sleep quality. Ren et al [25] indicated that the more favorable the pressure distribution of the mattress (i.e., the lower the peak pressure, average pressure, and pressure index), the higher the subjective comfort score. A possible reason for these results is that, in smart bedding design, changes in bed condition lead to instability in the users' body postures, and they require additional muscle activity to maintain a stable body position, consequently resulting in stretching and fatigue of the back and buttocks muscles.…”

“…The rating scale is one of the most fundamental and frequently used tools for evaluating subjective comfort [25]. We assessed perceived comfort using the Subjective Lying Comfort Evaluation on a seven-point Rating Scale [35], where −3 indicates the least comfortable and +3 denotes the most comfortable.…”

“…Existing studies on bedding comfort usually understand product comfort in terms of pressure perception. For example, Ren et al quantitatively analyzed how the layered structure of mattress bedding affected pressure relief performance and subjective lying comfort by investigating mattress support performance, interface pressure distribution, and subjective lying comfort; the results showed that pressure relief performance is an important factor influencing the comfort score [25]. Park and colleagues investigated the relationship between subjective sleep comfort and bed adjustment, and found that the hip/thigh area was under the most pressure, and, based on objective criteria, this area was the most uncomfortable [26].…”

Sleep quality is an important issue of public concern. This study, combined with sensor application, aims to explore the determinants of perceived comfort when using smart bedding to provide empirical evidence for improving sleep quality. This study was conducted in a standard sleep laboratory in Quanzhou, China, from March to April of 2023. Perceived comfort was evaluated using the Subjective Lying Comfort Evaluation on a seven-point rating scale, and body pressure distribution was measured using a pressure sensor. Correlation analysis was employed to analyze the relationship between perceived comfort and body pressure, and multiple linear regression was used to identify the factors of perceived comfort. The results showed that body pressure was partially correlated with perceived comfort, and sleep posture significantly influenced perceived comfort. In addition, height, weight, and body mass index are common factors that influence comfort. The findings highlight the importance of optimizing the angular range of boards based on their comfort performance to adjust sleeping posture and equalize pressure distribution. Future research should consider aspects related to the special needs of different populations (such as height and weight), as well as whether users are elderly and whether they have particular diseases. The design optimization of the bed board division and mattress softness, based on traditional smart bedding, can improve comfort and its effectiveness in reducing health risks and enhancing health status.

“…The

of the mattress with T 3D F padding layer covered the range between PU and LF, and the

of T 3D F 45 padding layer was softer than that of LF. Ren showed that the use of softer padding materials could effectively conform to the body and facilitate better shoulder and hip coverage [ 41 ]. Others found that the addition of a latex padding layer could effectively reduce mattress firmness compared to a firmer palm mattress [ 28 ].…”

Thermoplastic poly(ether/ester) elastomer (TPEE) has great potential as a mattress material due to its high resilience, breathability, and light weight. This study aimed to evaluate the feasibility of TPEE-3D fibrous material (T3DF), a three-dimensional block material made of TPEE fibers randomly aligned and loop-connected, for mattress application. After testing the compression properties of T3DF, the effects of T3DF structural layers on mattress firmness were investigated. The results showed that T3DF had good energy absorption capacity, broad indentation hardness range (126.94–333.82 N), and high compression deflection coefficient (2.79–4.39). The thickness and density of T3DF were the main factors influencing mattress firmness, and the impact of thickness was more significant (p < 0.05). Owing to the hard and soft segments contained in TPEE, T3DF could be used for both the padding and core layers of the mattress. The hardness value and Dsurface of the mattress with a T3DF padding layer increased with T3DF density but decreased with T3DF thickness. Moreover, the hardness value and Dsurface of the mattress with a T3DF core layer increased with T3DF density, while with T3DF thickness, its Dsurface increased and Dbottom decreased. Therefore, the thick and low-density T3DF padding layer could improve the comfort of the mattress surface, a thin T3DF core layer could satisfy both the softer surface and the firmer bottom of the mattress.
