Cushioning device

A cushioning device comprising:

• a cushioning member having a front wall surface adapted to permit the head or the neck of a user to rest thereon, and a rear wall surface opposite to said front wall surface in a first transverse direction and adapted to face an upright support, said rear wall surface having upper and lower edges opposite to each other in a second transverse direction which is transverse to the first transverse direction;
• a guiding member disposed proximate to said upper edge and having a first end disposed on said rear wall surface and a strapped portion extending from said first end in a longitudinal direction transverse to both the first transverse direction and the second transverse direction and terminating at a second end which is distal to said first end, said strapped portion having an inner frictional surface disposed to be spaced apart from said rear wall surface in the first transverse direction to define a passage therebetween;
• a strap member including leading and tailing ends and a flexible elongated portion interposed therebetween, said flexible elongated portion being of a dimension such that said flexible elongated portion is insertable into said passage and such that when said leading and tailing ends are adapted to wrap around the upright support about an axis which is parallel to the longitudinal direction so as to be pulled towards each other, said flexible elongated portion will be brought into frictional contact with, and will be retainingly slidable relative to said inner frictional surface;
• and a fastening member disposed to detachably interconnect said leading and tailing ends when said leading and tailing ends are pulled towards each other.
