We have another brand ring base swivel recliners and don't mount them to the floor. They have built-in plastic glides on the bottom which grip the floor and have never moved in thousands of miles of travel.
I like them loose. We can push them around for full recline, or to sit at our folding side table, or to lighten the too-heavy hitch load on our truck a bit when towing. When traveling we push them so the arms are close together in case they want to swivel, each holds the other.
You might give it a try before fastening them down.
