As of November 11, 2012, the PSUPedia and its affiliated wikis have made the transition to read-only mode. While edits can no longer be made, we hope you will continue to enjoy the data collected by the community for years to come!

Here is a full listing of known (offline) decorations with pictures in order to personalise your room to your desire. Some decorations are meant to be interactive or can be placed on other decorative items such as tables and shelves. Unfortunately this has not been implemented in offline mode. May possibly be resolved in future expansions.
