How wide are the recliner seats, i.e., inside the armrests?

Big like a couch

I'm not a thin person by any means and I found them plenty wide

Plenty of room to recline

Place was trashy last time I visited.

They are pretty wide and roomy. I can't say they are the most comfortable but they recline enough back to be comfortable. I like this theater better than most around because of the seating and laying back option.

Can't tell you exactly how wide they are, but they are very comfortable.
