I am going to take a stab at explaining making your bed and having to lay in it.
In our times we buy beds to lay in, not so much in the last century. Beds might be made of a tick stuffed with hay or if you were extremely lucky feathers (after many years of saving/accumulating feathers. The tick would be stitched up and to take it apart would have to wait to another day if there was a problem after the "bed" was made.
