Hopefully someone might have some info to help with my situation.

I'm currently working on turning my personal house into a Haunted House. I've got 3 Mannequins floating as part of it.

The problem is that Mannequins and other NPC items require another furnishing with collision to be placed under them to retain the appearance of floating.

Is there any item out there smaller than the Zabuton Cushion that has collision? The cushion ruins the effect I'm trying for because of the size.

I've tried a few items so far, including things like Dwarven Floor Lamp and Cutting Board, without luck. Nothing has had collision. I'm hoping someone might be aware of a smaller item that will work.
