Pseudocross

To organize a real cross in your home, or hidden in the cellar or on the attic, eventually behind a double wall or closet, you get a constant and incessant activity to prepare for use and store after.

I got the idea of a second possibility, a workbench, perhaps supported by trapezium feet, to stretch your naked body on, let arms and wide-spread legs hang, eventually aggravate your wrists and ankles, and lay for an hour.
Feel the rough wood on your occiput, in your shoulders, spine...
