PROBLEM TO BE SOLVED: To allow separation and replacement of an edge part and a bottom part so as to vary design by forming a coaster of disassemblability into the edge part and the bottom part. SOLUTION: A coaster is disassemblably constructed of upper and lower parts (edge parts) 2, 3 connected together at an interval 4 via a connection part 1 arranged in a part, and a bottom part 5. Although metal, plastic, paper fabric, and the like are available for using material, there is no limitation on materials. The edge parts 2, 3 may be formed into different shapes and can be designed variously. In this way, the edge parts 2, 3 and the bottom part 5 are separately formed and can be replaced with another one or removed, so that variation and enhancement of design can be accomplished while washing can be facilitated.
