“…6,7,16,17 Because these products were highly similar, the differences between them could not be easily distinguished; and thus, an influential design factor of pillow design could not be easily identified. However, the present study incorporates the importance of deconstruction analysis to investigate the effects of pillow design factors.…”

“…In addition, a number of previous studies used subjects' daily pillows as control pillows 10,16,17 ; thus, if subjects were unsatisfied with their daily pillows, the testing pillow received a high rating, thereby possibly causing a placebo effect. Therefore, the present study used 4 pillow design factors to eliminate biased comparison under different basis and produce more accurate results.…”

“…Previous studies focused on sleep quality and neck ailments. [5][6][7]10,16,17 The subjects were primarily hospitalized patients and hospital staff. Subjects were not selected on the basis of consistency with in terms of the pain, symptoms, and the specific pillows were provided for specific patients.…”

Objective: Few studies have analyzed the shapes of pillows. The purpose of this study was to investigate the relationship between the pillow shape design and subjective comfort level for asymptomatic subjects. Methods: Four basic pillow designs factors were selected on the basis of literature review and recombined into 8 configurations for testing the rank of degrees of comfort. The data were analyzed by the analytic hierarchy process method to determine the most comfortable pillow. Results: Pillow number 4 was the most comfortable pillow in terms of head, neck, shoulder, height, and overall comfort. The design factors of pillow number 4 were using a combination of standard, cervical, and shoulder pillows. A prototype of this pillow was developed on the basis of the study results for designing future pillow shapes. Conclusions: This study investigated the comfort level of particular users and redesign features of a pillow. A deconstruction analysis would simplify the process of determining the most comfortable pillow design and aid designers in designing pillows for groups.

“…Previous studies (Lavin et al, 1997;Erfanian et al, 2004;Chen and Cai, 2012) analyzed anthropometry, designed a new contoured pillow and analyzed design factors' effectiveness according to sleep duration through a video analysis. Gordon et al (2009) conducted a survey on pain and satisfaction with sleep according to the use of each pillow type, and the study result reported that pillows made with rubber showed higher satisfaction with pain relief, compared to the contoured pillow.…”

Objectiv e:The aim of this study was to evaluate the effectiveness of 3 dimensional contoured pillow through analyzing contact pressure and to suggest its design guidelines through analyzing the posture of head and neck area.Background: The quality of sleep is a very important factor closely related with human's health. To improve the quality of sleep, the verification of design factors affecting the posture of the head and neck is needed, and a pillow design that can induce proper posture is required.Method: This study measured the contact pressures of the two reference groups (bead and cotton pillows) as a method to evaluate the design effectiveness of the contoured pillow. This study proposed 3-dimensional design guidelines by drawing anthropometry (head length) affecting cervical curvature angle (CCA) through the measurement of the participants' cervical curvature angles. Results:In the design effectiveness evaluation, the contact pressure of cervical region was higher than that of a reference group (cotton pillow), and contract area increased, and contract pressure decreased in the shape distributing the occipital region's body pressure. This study proposed pillow's cervical supporting height by percentile of a head length [head length (%tile) (cervical supporting height) affecting the posture of the head and neck: 14.6cm (5%tile) (6.2cm), 15.5cm (25%tile) (6.7cm), 16.4cm (50%tile) (7.1cm), and 19.3cm (75%tile) (8.9cm)]. Conclusion:This study confirmed the contoured pillow's design effectiveness maintaining cervical angle comfortable to sleep with the shape supporting the cervical vertebrae and by reducing the contact load of the occipital region. Also, this study proposed pillow design guidelines based on the 3-dimensional contoured pillow design effectiveness, through which the study laid the foundation for pillow design in a systematic method.
