This is the place where my bed frame fits together.
It caught my eye a couple days ago.
There are four corners that look like this and hold the bed frame rigid so that it will stand and support the piece of plywood that holds the mattress.
Once it had springs but they are long gone.
I've slept on this bed most of my life. It was given to me by my paternal grandparents when I was three.
Something that had been abandoned and that they didn't need.
When we were young my brothers and neighborhood friends would fold the top part of the mattress over so that it made a seat. (It was a very thin mattress, maybe 3 inches deep and probably original to the bed.) We would sit there and bounce up and down pretending it was a wagon and we were off on grand adventures.

I am thinking about fit,
how things fit together to make something work.
Edge to edge.
How things snap together.
How things hold.
