Added Roadblocks

These three OLD chairs sit in our hallway and are fitted together like a puzzle without any glue or nails, which makes them very fragile. 
However, people will invariability sit in them and I have to explain that they should not be sat upon as they could fall. Which would dump the occupant out and that could hurt them. Also, people put coats, hats, packages, etc to rest on them. 
I thought about getting some ropes like they use in Church to block off a section of pews but settled on some objects I had in the house. 
The Kitty Justice is that the objects still have not stopped either people or items landing in the chairs. I need to steal some ropes from the Church or add barb wire.
