Way back I made a Jack and Jill seat out of cheap lumber (as I do).
It is our (myself and my wife’s) most used seat. A place for a relax with a cup of coffee most mornings.
At times someone will comes by for a chat. But there’s no accommodation for a third wheel.

I have an idea!
Why not a Jack and Jill and Jerry seat?
I’ll eventually come up with a better name than that – any name ideas?
The picture below is a photoshop.

I am going to make one and it will probably be my next project. I think it will be most useful.
