I sleep on my front and I like being able to put my feet over the end of the "bed" in Club World, which isn't possible in most other business seats. I also like that it is square and not narrow around the feet and shoulders. With a bit more padding (which is on its way?) it would be a good night's sleep. I recently flew LHR-SYD on SQ to try out some alternative carriers and the seat looked great, but in practice was not as comfortable as it promised, either as a seat or as a bed.
