TECHNICAL FIELD OF THE INVENTION
The present invention relates to beddings such as futons, mattresses, pillows, cushions and the like.
[0002]
[Prior art]
Pressure ulcers (so-called floor rubs) may occur when a specific part of the body is pressed for a long time when the posture cannot be changed frequently on a bed or chair.
As a kind of bedding for preventing this pressure sore, a donut-shaped cushion made of an annular buffer is known.
It is recognized that this cushion can prevent the occurrence and deterioration of pressure ulcers by buffering body pressure applied to a specific part of the body, particularly the affected part, by the cushioning body (for example, see Patent Document 1).
