What kind of seats are these?

Not sure, but they look like Berkline 12003s; if Roman chimes in, he'll know.
That theater looks incredible.

Yes, they are probably the Berkline 45094, "Hollywood" judging from the look of the leather. The import version of this chair is the Berkline 12003, now made by Lane (and still available) and called the 103.

And yeah, nice theater!
