So, Straddle pose is staying.
IMVU has said this item is ok for GA (I have an email from Nino himself.)

The sort of things that may get your couch sent to APO:
Any AP clothing (or lack of any clothing)
It needs to be merchandised as a GA product (No implication that it can be used as an APO item)

The poses on this couch are meant to have close contact with the person you are talking to. There are two seats that allow those that don't want to be "Jumped on" to allow them to sit on their own and have a regular conversation.

There are also the "Couple poses"
A straddle in the middle
A head on lap while the other pets
A backrub with a person sitting in front of the other on the floor

The mesh is by Stuzzy and it is Derivable
