Airline seats  

There are many threads in this Forum about living room chairs but very few about airline seat quality.

Which manufacturer makes more comfortable seats, Sicma or Recaro?
And is it possible to get good sleep on the Club World sleeper seat, like Tangerine and British Airways say?

This is very important question for business travellers who fly frequently, because supersonic transport future(Concorde, Tupolev 144, Boeing 2707 etc.) is probably over. So flying to distant destinations still takes many hours.
