Ah sorry, I misread the word "sets" for seats

Yes it does look a bit different and frankly it's a very cleaver solution as I'm not too fond of having pillows and blankets at the seat when I board. Not only do they take up a lot of space it's quite challenging to find a place to stove them away as you want to use the space for your own stuff.

It's a better solution to have the bedding stored in a closet or a separate bin, only to be taken out when the passenger actually wants to sleep.
