What are you sitting on?

My wife and i are at the midpoint of our new dedicated room construction and thoughts have now turned to furniture...

We want to have the ability to enjoy this room ourselves but also with like minded friends! [probably no more then a couple of extra people at a time ]so...

As far as chairs, couches, etc.etc. what did you find that gave great comfort and proper height and that can be integrated at the same time?

Room is 26 by 20 by 11ft...

Thanks to you all and have a Happy Thanksgiving.
