Length: 55cm Diameter: Approximately 6cm Color: Blue Donut-shaped cushion for pressure distribution With Velcro, it can be easily attached to hands, feet, and head as a bedsore prevention tool. (Attachment methods can be devised.) Can be used for back sleeping, side sleeping, face-down sleeping, and in wheelchairs. Not only for preventing bedsores, but also as a leg pillow and elbow rest. Good breathability, can be used all year round. Machine washable (do not tumble dry). I have washed it by hand or in the washing machine on a delicate cycle. There is a general feeling of use. It will be placed in a plastic bag and slightly compressed for shipping.
