By doing this cheat you can make some smaller condo items fly! (not chairs or tables, I’m afraid) This cheat is old and I didn’t discover it myself. The cheat hasn’t been mentioned in this site before so I decided to do it.
This cheat works only on furniture that can be put on tables.
Step 1. Put the piece of furniture you want to make float on a table. (It can be any table)
Step 2. Go to your inventory and remove the table from the room.
Step 3. Select the furniture and move it wherever you want it to be.
1. If you have problems with getting your piece of furniture down again just put a table in your condo and place the item on table.
2. If you want the item to float higher make the table bigger before putting the item on it.
