To answer g_bartman, I don't know what they don't like about the HT chairs...but, here is what I think/know:
I keep it about 69 degrees in the basement and they (my girls) claim the cloth chairs and couch are warmer. Also, my kids are used to the cloth chairs since that is what they have in their "media room" while my wife is used to leather in the family room, so she goes for the HT chairs in the basement with me.
The kids like to lay down during the movies so they fight over the couch while my wife and I fall asleep if we take the couch.
I notice that when guys come over they go for the HT chairs and when the kids have friends (girls) over they often go for the cloth chairs or couch, but I don't have a large enough sampling to say it is a gender thing.
It could be a size thing, both me and my wife fit in the larger HT chairs better than the skinny kids.
As the only male in the house, I have given up on why the rest of the family does what they do. From watching low def on 70 inch TV when most channels are in HD to them watching Honey BooBoo. This is why we have multiple media areas and three DVRs.
