After reading a pretty funny story on official forums about this guy who realised after 3 years of decorating that there was accurate commands to move items in a house.
So to avoid his mistakes, here are the commands for moving items in your house:

/move forward 1 to 500

/move back 1 to 500

/rotatefurniture yaw 1 to 360
(Add a - before the number and you rotate it the other way)

If you wanna roll or pitch the item, you first gotta complete the 2 collections granting the abilities. Then the commands are:

/rotatefurniture pitch [Ammount]
/rotatefurniture roll [Ammount]

//Twin

To shorten that a bit...

/rotate yaw
/rotate pitch
/rotate roll


also work and instead of that a you can use a minus (-) ^^

Easy collection.
