Those hard red seats on SBS9378C, Wrights, Citaros and KUBs are
very uncomfortable in my opinion...
Volvo Olympians, LO3X, VSO, B10Ms, MAN A22, B9TL CDGEs are more
comfortable...

SMRT's seats is a better choice as compared to SBST.
(Oh no, I'm thinking of the former comfortable seats of
SBS9889U...)
But somehow, SBST has already adapted to these red and yellow
seats, what to do?
