If you ever look at Audio Video Interiors, most of what you see will be movie theater seats. For me having a sofa and chairs puts the "home" in home theater. My setup is just one GIANT L shaped sofa(it didn't look that big in the store) with no room for other chairs. When I was single I put a chair right in the middle of the room. My screen is 10 feet wide so I felt like I was at an IMAX. I have Tannoy studio monitors that I used to move in as close as possible because they are near field monitors. It was Awesome. But now that I am married I have something even better than home theater. We sit centered on the sofa about 15' away from the screen. I have an 18" Bag End sub behind the sofa that shakes the sofa much like a transducer would. The sofa is so big that with the foot stool in front of us we can recline or sit up. We can also move over to the corner and lay down to watch. As far as the Sweet spot goes I just calibrated the speakers to middle of the sofa.
