This occurs for me on all pre-made houses by Maxis.
Sim's won't interact with a bed unless the whole lot is made by the player.

I use mods, especially ones which heavily customize the game - but if it would a mod Problem I think the beds in General would stop working.

It seems to be caused by mods which Change the animations when interacting with beds.
Now it's the fridge my sims won't use because something is in the way :/
EDIT (crin): Replaced Mod Links with mod names. Please do not link mods at AHQ
