This may sound like a silly question, but oh well. I have wood floors throughout my house (new recently built), and I have my sofa and loveseat in the middle of my living room (not up against a wall). Every time a person goes to sit down, the sofa or love seat slides back. I'm constantly having to move the sofa back to its place. What do you all use to keep your furniture in place to keep from sliding? Placing up against a wall is not an option by the way.
