Note, if you put things on the footboard surface you will need to use the move objects cheat to place the mattress. Now it will work with many beddings without them clashing with the frill and you can put things on it easily without all that computer keyboard clicking things up and down. So I took the bed, made it mattress-free to go with my Sophia Double Mattress, put 14 slots on it, and ripped off the frill. And the frill underneath the frame is an impediment to using the bedding you want while also having it match the frill.
I like EA's Single Mission Double bed frame but I've often felt that it could use some slots for the wide surfaces on the head and foot boards.
