Help! Whenever I spawn on my map, all of the chairs in the next room over go flying into the air, as if there were an explosion. I cannot get it to go away either. It is only the chairs and the table, nothing else moves. Someone help me!!

Don't place prop_physics models right on the surface of a brush. Always put them a few units higher (4-8) so they "settle" on the ground when the map spawns them.

What Dash said. If you want them to be a solid prop, as in they cant be moved or destroyed, make them prop_static which then you can place right on the ground.
