Oasis Hong Kong B747-400 are those ex-Singapore Airlines aircraft with orginal Singapore Airlines seats... So their seats should be better than Virgin with much better back support and also much more comfortable...
Looking at information from Singapore Airlines, their Economy Class seats should have a seat pitch of 32" and width 17.5" which is slightly better than Virgin Atlantic 31" seat pitch an 17" wide seat...
