How to have destructible objects in a destructible building

I want destructible objects in my destructible buildings. For example a chair in a building.

However all tutorials I can find rely on using a permanent anchor field for destruction. This would mean that when my building is destroyed, the part of the chair in the anchor field would continue to float.

Yet without an anchor field, the chair immediately disintegrates.

I haven’t yet found any video or advice explaining how to do this more complex form of destruction, only simple objects.

Despite all the available tutorials, wouldn’t even know how to place one destructible barrel on top of another without a hovering component at the end.
