[0024] Here, the mattress body 1 is a rectangular plate with a predetermined thickness, and as shown in FIG. 4, a rectangular installation opening 11 is formed at the center of the mattress body 1, while a stopping plate 12 is formed in an upstanding form at one end of the mattress body 1. Particularly in this mattress body 1, preferably rectangularly bent engaging pieces 13 are secured on the inside walls of the installation opening 11 by using a fastening means N such as bolts and nuts.

[0025] Further, the stacked part 2 consists of a series of stacking elements which are installed within the installation opening 11 of the mattress body 1. As shown in FIG. 4, the stacked part 2 includes: a stone plate 21 for forming the surface of the mattress body 1; a supporting plate 22 installed under the stone plate 21, for serving a shock-absorbing role; an electro-heating plate 23 for carrying out an electrical heating; and a fixed plate 24 for serving a supporting role, the mentioned elements being stacked in the cited sequence.

[0026] Further, the securing plate 3 is a securing means for maintaining the coupled stacked elements of the stacked part 2 firmly in a sealed state. Preferably this securing plate 3 is a rectangular planar structure which is installed by using a fastening means N such as bolts and nuts.

[0027] Further, the supporting frame 4 is one of the essential features of the present invention, for supporting the mattress body 1 and the securing plate 3. This supporting frame 4 is preferably of a rectangular structure, having a plurality of detachably assembling holes 41 at its center and at the four corners of the supporting frame 4 respectively.

[0028] The supporting legs 5 are the usual supporting means, and are assembled into the detachably assembling holes 41 respectively. Each of these supporting legs 5 consists of a round post, and has a fastening thread part 51 as shown in FIG. 3 (here, the movable rollers are not illustrated)

[0029] As shown in FIG. 1, preferably a movable roller 52 is installed at the opposite end of each of the supporting legs 5, opposite from the fastening thread part 51, so that the stone bed can be conveniently moved.

[0030] Accordingly, the mattress-integral stone bed of the present invention constituted as described above is assembled in the following manner.
