“…Very few studies have attempted to determine the shape of the plantar surface of the foot even though contact or the lack of contact between a foot and shoe will alter the force distribution along the plantar surface, especially in the mid-foot region (Alemány et al, 2003). The firmness, anthropometric features and pressure distributions (Na et al, 2005, DeVocht et al, 2006 are all factors known to contribute towards comfort (Lee and Park, 2006). …”

Orthotics and other types of shoe inserts are primarily designed to reduce injury and improve comfort. The interaction between the plantar surface of the foot and the load bearing surface contributes to foot and surface deformations and hence to perceived comfort, discomfort or pain. The plantar shapes of 16 participants' feet were captured when standing on three support surfaces that had different cushioning properties in the mid-foot region. Foot shape deformations were quantified using 3D laser scans. A questionnaire was used to evaluate the participant's perceptions of perceived shape and perceived feeling. The results showed that the structure in the mid-foot can change shape, independent of the rear-foot and forefoot regions. Participants were capable of identifying the shape changes with distinct preferences towards certain shapes. The cushioning properties of the mid-foot materials also have a direct influence on perceived feelings. This research has strong implications for the design and material selection of orthotics, insoles and footwear.

“…According to Kim et al's study (1997), bed type not only sleep quality but also subjective sleep ratings. An optimal mattress should facilitate higher sleep quality, and should consider individual differences in order to facilitate deep sleep (Park, 2006). When subjects slept on mattresses with poor stability or high hysteresis, the percentages of deep sleep and sleep efficiency were low, while the percentage of waking after sleep onset was high.…”

Mattress, as a sleep platform, its types and physical properties has an important effect on sleep quality and rest efficiency. In this paper, by subjective evaluations, analysis of sleeping behaviors and tests of depth of sleep, the relationship between characteristics of the bedding materials, the structure of mattress, sleep quality and sleep behaviors were studied. The results showed that: (1) Characteristics of the bedding materials and structure of spring mattress had a remarkable effect on sleep behaviors and sleep quality. An optimum combination of the bedding materials, the structure of mattress and its core could improve the overall comfort of mattress, thereby improving the depth of sleep and sleep quality. (2)Sleep behaviors had a close relationship with sleeping postures and sleep habits. The characteristics of sleep behaviors vary from person to person.

“…On the contrary, other papers have shown that certain mattresses could lead to a better sleep quality in healthy people (Jacobson et al 2006;Lee and Park 2006;Jacobson et al 2008;Jacobson et al 2009;Tonetti et al forthcoming). The results of these studies are hardly comparable because different types of mattress were examined and different tools were used in order to determine the effect of the mattress on sleep quality: polysomnography (PSG) (Suckling et al 1957;Rosekind et al 1976;Okamoto et al 1997;Scharf et al 1997;Okamoto et al 1998;Bader and Engdal 2000;Lee and Park 2006), actigraphy (Tonetti et al forthcoming) and questionnaires (Jacobson et al 2006(Jacobson et al , 2008(Jacobson et al , 2009.…”
