Do: If you want to provide comfort, coziness and a hospitable seating arrangement for your guests, clearly the dining chairs exhibited on the photo on the left will do the job.
Do not: On the other side of the coin, if you anticipate guests who gossip needlessly, talk rubbish and make you pine for lost brain cells, then by all means make them sit on these modern rocking chairs (shown on the right) while they eat. However, just be ready to clean up vomitus in the bathroom because sitting on these inventions while you eat guarantees the nauseum in ad nauseum.
You sneaky hostess you...
