mine sits in place nice and tight too - the black seat material is up against the body work all the way round except for where the grab handle comes out.
Can you see if the screws are actually in place to hold the seat down?You need to pull the seat material foward slightly along the back edge of the seat and there are 2 screws under there.
I have heard of some service techs struggling to get them in - so just leaving them out :???: - or putting them in to hold the rear bodywork in place and just sitting the seat on top of them.
It is not difficult when you know how - just needs some practice.
If the screws are there then sounds like something is out of place.
