Abstract: A bed sheet set includes a base unit, a cover unit and a connection unit. The base unit includes a bottom layer, a surrounding layer that extends upwardly from a periphery of the bottom layer, and a top layer that is connected to a top peripheral end of the surrounding layer. The cover unit is detachably mounted to the base unit, and includes a functional layer that is disposed over the top layer of the base unit, and a side layer that extends downwardly from a periphery of the functional layer. The connection unit includes a first connection component that is mounted to the surrounding layer, and a second connection component that is mounted to the side layer and that is detachably connected to the first connection component.

Abstract: A bedding assembly includes a cushion, a cushion cover, a top cover and a coupling unit. The cushion has opposite lateral surfaces. The cushion cover accommodates the cushion and has opposite first and second cover portions that are respectively adjacent to the lateral surfaces of the cushion. The top cover is laid on top of the cushion cover and has opposite first and second side portions that are respectively adjacent to the first and second cover portions of the cushion cover. The coupling unit includes a first coupling subunit that separably couples the first cover portion to the first portion, and a second coupling subunit that separably couples the second cover portion to the second side portion.
