(Bumping the thread, as I'm in the same boat)
Did you take the plunge on the theater seating for your dedicated seating?
I'm also in an open concept apartment where the kitchen area, office, and living room share the same open space. Me and the girlfriend live together and she was all for it (aside from the expense of the chairs, but I told her "you gotta put your money where you put your time", and we watch a lot of TV, so it was an instant approval, lol). We'll probably get a leather matching couch (different seat design likely) at some point in the future, but for now, we have an inherited couch and loveseat we can put along the wall for family and crashing on.
I'm looking at getting some Palliser Elite curved home theater chairs. I've tried 15 of Pallisers current 25 home theater chairs, and while the Elite one wasn't the nicest looking design, it was by far the comfiest we found (the HiFi was a close second, however the leg rests seemed like they were designed for someone taller, as my calves were uncomfortable on them through reclining).
Any additional advice anyone has on this subject would be awesome.
