Bedding structure with improved door/tracking system

A bedding structure comprising:

• a side wall;
• two opposing end walls;
• two flexible doors opposite said side wall and acting as closure means between two end walls, with each of said flexible doors being bendable and slidable so as to be in parallel orientation with said end walls, when said flexible doors are in a fully open position, said flexible doors further including mesh material to create closure;
• and
• a tracking system for accommodating said flexible doors from above and below, having both top and bottom portions, wherein said tracking system bends through 90 degree angles to allow said flexible doors to open from a closing engagement to a position where said doors are fully open and in a 90 degree orientation to said closing engagement said tracking system including a stationary track above and below said mesh material, and further including a holding member to which said mesh is secured, and a gripping structure, attached to said holding member, slidably engaging and fitted over said stationary tracks.
