Furniture & Objects may include the following different types of files:
.iff files can be placed in any 1 of 3 objects folders, skin parts for objects need to be put in your gamedata\skins folder.

Sims can't use an NPC object
Usually this happens because other visitors to the lot are using the object. Your Sims will have to wait their turn. This is very common with Food stations, Bars and Pet Pens.
Check that you have installed ALL .iff files in the zip, most NPC objects consist of multiple .iff files all of which must be in your game for the object to work
Hotels & Restaurants will not function if you don't have other required object types on the lot (i.e. beds, fridges, sinks etc). These required objects must be accessible to Sims
Objects are the most problematic type of Sims 1 custom content. If your game is crashing or you have issues using custom objects then try the following resources.
