You should be pretty comfortable. I'm 6' 1" and rode 8E from IAH to LHR a couple days ago, and was fine. The extra leg/foot room in the ottoman was most welcome.

The only complaint I had about the seat was the fact that the headrest seems to get in the way if you are a side sleeper. I like to tuck my arm up under my head when rolled on one side, and the headrest is in a horrible position to allow you to do so. I wish that the headrest pillow could be removed somehow.

Other than that, the seat was very comfortable. I probably spent more time with it in recliner mode than actually sleeping.
