Hey there
Ok you can only use the "chair x" If you try it
you can actually move through this object! If you look
closely you will see that the unit, when he sits, actually
sits just below the chair seat. So just position the unit
in front of the chair, then use switchmove"fxstandunivtable"
then to get the unit to stand switchmove"fxstandfromtable"
Hope this helps!
