For your full futon bunk bed to be in harmony with the whole room, do not settle for a Japanese style bedding. Think squarely of a Japanese-inspired decoration. A Japanese style room is very minimalist. It contains only the necessary for sleep namely the bed and bedside tables. It may be that a small coffee table is installed facing the bed knowing that it is placed in the middle of the room, the headboard against the wall.
Then, it is better to install closets that disappear into the walls than a wardrobe or an imposing dresser. If there is no closet in the room, find here some tips to create one yourself. On the other hand, the furniture is low and there is practically no space between the bed base and the floor. Moreover, the bed frame is usually wider and the futon is placed in the middle.
The bed is square and bed linen (sheet, duvet cover etc.) is plated on the side and folded under the futon. A Japanese style room is also very pampering. The floor is covered with a carpet or a soft carpet and some cushions are placed here and there, to sit when one meditates or for other moments well-being of this kind.
