  • an elastic body having a top face, an outer circumference of the elastic body being formed with a fixing flange with a certain thickness, the elastic body defining therein a receiving section for containing air, a bottom of the elastic body being formed with a vent; and

    a base seat including;

    (A) multiple outer frames that can be assembled into an annular structure, an inner circumference of each outer frame being recessed and formed with a restricting channel with a certain height, two ends of the outer frame slightly outward extending to form two abutting sections for connecting with adjacent outer frames; and

    (B) multiple reinforcing boards which can be assembled into a circular board, a lateral side of each reinforcing board having a horizontally projecting upper connecting plate, while the other lateral side thereof having a projecting lower supporting plate corresponding to the upper connecting plate, whereby the upper connecting plate can be overlaid on the lower supporting plate of an adjacent reinforcing board and connected therewith to fix the reinforcing boards with each other, inner side of the reinforcing board being formed with an inner arch, the outer circumference of the reinforcing board having a certain thickness, whereby when the reinforcing boards are assembled, the inner arches together define a small circle at the center to communicate with the vent, the thickness of the fixing flange plus the thickness of the outer circumference of the reinforcing board substantially being the height of the restricting channel of the outer frame, whereby the reinforcing boards and the elastic body can be firmly enclosed by the outer frames.
