“…30 It has been estimated that more than 80% of the American public sleep on innerspring mattresses. 53 As previously done by others the current study used a medium-firm 29,31,41 innerspring mattress as the experimental bedding system and found immediate and significant improvements in sleep quality, sleep efficiency, and stress among participants. No benchmark standards presently exist for recommending bedding systems, whether for the purpose of alleviating pain-related sleep disturbance, stress, or for the purpose of enhancing sleep quality.…”

“…41 Several studies have concluded that stress is highly related to poor sleep quality 6,15,[18][19][20][42][43][44][45] and that stress has been associated with insomnia and insufficient sleep. 14,42,46,47 Less defined is the reverse association between sleep quality and stress.…”

“…As is common with most sleep surface research, no control group was used for comparisons, 28,29,32,37,40,41 but rather the group served as its own control. It is axiomatic that a control group strengthens the research design by reducing the threat for a Rosenthal effect.…”

Objective: This study compared sleep quality and stress-related symptoms between older beds (≥5 years) and new bedding systems. Methods: A convenience sample of healthy subjects (women = 30; men = 29) with minor musculoskeletal sleep-related pain and compromised sleep, but with no clinical history of disturbed sleep, participated in the study. Subjects recorded back discomfort and sleep quality upon waking for 28 consecutive days in their own beds (baseline) and for 28 consecutive days (post) on a new bedding system using visual analog scales. Following baseline measures, participant's beds were replaced by new, medium-firm beds, and they again rated their sleep quality and back discomfort. Stress was assessed by a modified stress questionnaire. Results: Repeated-measures analysis of variance was used to treat sleep quality and efficiency and factored responses of the stress items. Results indicated that the subjects' personal bedding systems average 9.5 years old and were moderately priced. Significant (P b .01) improvements were found between pre-and posttest mean values in sleep quality and efficiency. Continued improvement was noted for each of the 4-week data gathering period. Stress measures yielded similar positive changes between pre-and posttest mean values. Conclusion: Based on these data, it was concluded that, in this population, new bedding systems increased sleep quality and reduced back discomfort, factors that may be related to abatement of stress-related symptoms.

“…The parameter is the stiffness level of mattress where (N.mm) is the work demanded to compress the core with a maximal force of 450 , and (N/mm) is the average differential firmness. The value of the tested surface was measured to be 1250 mm2, which is close to the normal stiffness level of mattress according to the standards provided in the literature [16,26] . The E values was obtained by measurement of the total area under the loading curve ranging from 0 to 450 N, and the parameter C was obtained using the mean slope of loading curve tangents at points of 210, 275 and 340 N in consistent with the standard method ISO 2430; 2001.…”

Background: Neck and back pain are the most common reported musculoskeletal disorders. Applying surface electromyography to determine muscular activity has been used for a long time for clinical diagnosis. OBJECTIVE: The aim of this study was to assess the effect of two sleeping postures (recommended and preferred postures) on neck muscles activities and fatigue by measuring cervical muscles activities using electromyography. In the recommended posture (Model 1), the cervical and lumbar spine are horizontally aligned, while in the preferred posture (Model 2), the cervical spine is not aligned with lumbar spine. Methods: A total of nine healthy male subjects were asked to side rest with a pillow with adjustable height. The electromyography examinations were performed for upper trapezius (UT) and sternocleidomastoid (SCM) muscles of participants. After acquiring the anthropometric data, participants laid on mattress with medium hardness at the two postures for 30 minutes. Results: Comparison between the two models showed a significant difference ( ) in the level of electrical activity of neck muscles. In addition, a remarkable difference ( ) was observed in terms of neck muscle fatigue between the two tested models. Conclusions: The results indicate that the recommended posture developed and tested in this study would reduce the level of fatigue and activity of neck muscles during resting.
