OK all right already. I'm goaded and shamed to go ahead and remove a bed that has taken up space for 10 years. It is wrought iron.
Last time I tried I failed. This is a job for a meson disintegrator but it isn't invented yet. There must be another way. I may end up having to use a sawzall and fire extinguisher. I wonder if the old fashioned coil spring under mattress has any tales to tell.
