Abstract: A portable stool has an enclosing wall assembly `A` and a flat seat `B` both made of the same or different plastics. The enclosing wall assembly is rectangular in plan view in its extended state and consists of a pair of right and left side walls (1a,1b) and a pair of front and rear transverse walls (2a,2b). Either the pair of side walls or the pair of transverse walls respectively consist of vertical halves hinged by mediate joints (4) to each other. Each side wall having a front and rear vertical edges is foldably connected by corner joints (5) to the transverse walls at lateral and vertical edges thereof adjacent to the former vertical edges. A back side of the flat seat `B` has at least one members (7) capable of fitting on or in at least one other members (6) formed on an upper end of the enclosing wall assembly `A`, such that the instantly openable and closable stool can withstand the body weight of any user including children, allowing the children to use the stool safely and many times.

Abstract: A toilet seat cover for a toilet seat including a sheet made of unwoven fabric having a shape corresponding to a shape of an upper surface of the toilet seat, and a mount layer including synthetic resin emulsion and applied to one surface of the sheet. Upon placing and pressing slightly the toilet seat cover against the toilet seat, air in pores formed in the mount layer is discharged, thereby reducing pressure in the pores. Accordingly, the toilet seat cover can be easily attached to the toilet seat due to the vacuum suction force. Further, the toilet seat cover can be easily detached from the toilet seat by peeling the mount layer therefrom, leaving nothing on the toilet seat. The sheet has a laminated structure including a fabric layer, a porous buffer layer which provides comfortable seating and good heat insulation effect, and a permeation inhibitor layer for inhibiting material of the mount layer from permeating the porous buffer layer.
