chattel (personal property)
Any item which is not permanently fixed to a property.
Chattels are never included in a sale unless they are specifically named in the Agreement of Purchase and Sale.
It's normal and expected for the seller to take "everything that isn't nailed down" when they move.
The most obvious examples of a chattel are a couch, chair, or coffee table.
Some less-obvious examples of a chattel are a fridge, a free-standing stove that is not built into the counter-top, a hanging mirror, and even a swag lamp that is hung on a hook and plugged into the wall.
Contrast with fixture.
