Wow, funny this thread popped up when it did. Don't get your hopes up, I didn't find any of the ottomans, but we did settle on some overflow seating that should work out pretty well. We found some comfortable resin adirondack chairs at Menards for $16 a piece. They're low to the ground, stackable and have good lumbar support. They make a great front row if you don't have a riser (and we don't). They're no more of an obstruction than a guy sitting in front of you in a conventional theater, but fully reclining in the back row might be a problem.
Here's what looks to be the same chair:http://canadiantire.ca/AST/browse/2/....jsp?locale=en
We might even try to make some darker colored slip covers with a little padding, but to be honest, they really don't need it... I spent a couple hours in one while cleaning off the DVR last night. Worked like a champ (and I'm even fighting a bad back right now... just be sure to try them out, some of the non-ergonomic chairs are pretty bad). And at that price, I won't feel bad when we stack them up and send them to the basement for the other 362 days a year when we don't need 'em.
I've got some pictures at home. I'll try to post them tonight.
