We have floor hooks also, but don't use them. Don't tie down dinning room chairs either; thou we only take two with us.
In the interest of full disclosure we don't have either chair in the rear that came with the trailer. Street side is either empty or has dog crate. Curb side has a recliner with a separate leg/foot rest. Don't tie either down and have not had a problem.
We don't travel on really bad roads, mostly secondary roads or the interstate if necessary.
