Hi sueoverend,
What airrcraft are you flying on? Ifo n a 747-400 and you have an upeer deck window seat then you can use the side bins for storage ( a great benefit). Otherwise there is the pocket in front of you.
There are diagrams by the seat controls which are reasonably straightforward.
Also there is a small drinks tray and the tv screen swivels out.
The foot stool can be released and moved up to complete the bed ( or just for relaxing).
Enjoy!
Regards
TBS
