I flew Club on my flight to Cape Town this Xmas-personally, I found that the seats were indeed a little too narrow for my liking-I'm barely 6', so the length was more than enough, but I found difficulty in sleeping, as my elbows constantly brushed the sides.
It may look cramped, but once you get settled down, and setup the partitions, you feel relatively 'private', and the cabin actually 'feels' quite spacious-if I may use that word.
A nice touch are the vintage B&W photos of old BOAC a/c in various airports-repeated inside the toilets.
What annoyed me was that I had to ask for an amenity kit, as these are not apparently handed out, like they used to be.....
