Bear in mind that, in a sudden deceleration (i.e. a crash), the weight of an item does NOT ensure it will stay put. The force on the item caused by the decel is proportional to weight and the friction force between the item and the floor is also proportional to weight.
Getting a sugar bowl in the back of your neck is one thing. Getting a 250-lb recliner in the back of your neck is something else again, and probably not good for the neck. I, personally, would not have any furniture in my RV that wasn't firmly bolted down.
That aside, I hate barrel chairs. They have to be the most uncomfortable pieces of furniture ever conceived. Our rig has one between the front passenger seat and the house door. The only thing we use it for is to clip the Labrador's harness to the seat belt. I don't think either of us has ever sat in it for more than a few minutes.
It would've been far better if FR had moved the house door forwards, eliminated the barrel chair and extended the kitchen counter.
