This is the correct method of laying bed in AC class. We are provided with sheets and quilts (2 sheets and one quilt is provided).
The steps are as follows-
1. Take everything away from the bearths ,lift it in the case of middle bearth.
2. Take the quilt and fold it in the rectangular shape of the bearth and lay it.
3....
more... Then take one of the two sheets provided and do the same as step two.
4. Place the pillow at desired end and use the other sheet as a blanket.
(Note- The quilts are washed rarely so dust and dirt is present. That is why a sheet is placed on it. Do not use the quilt as a blanket.)
