Murphy bed

The Murphy "hide away" bed is a type of bed introduced in The Sims 2: Apartment Life expansion pack. The bed folds into wall as to save space in the small apartments that are added with the game. However, when closed, the tiles it would use if opened are still considered to be in use. While Sims are able to walk through that space, objects cannot be placed in that space without using the moveobjects cheat. When the cheat is used to place an item in that space, it will probably show through the bed unless the item is small enough to go unnoticed.

Murphy beds have returned in The Sims 3: University Life.

Death by Murphy Bed
In The Sims 2: Apartment Life, if a Sim with fewer than five body points and a mood of less than -70 opens the bed, there is a 5% chance that the bed will fall on them and crush them to death. The ghost of a Sim who dies from being crushed by a Murphy bed is white, and will avoid the bed.

In The Sims 3: University Life, failing to open or close a Murphy bed may result in the Sim's death. The ghost of a Sim who dies from being crushed by a Murphy bed is light red/pink, and feathers fly around the Sim.

The Big Sleep Murphy Bed
Maybe you're hunting for bedroom space. Maybe you want to feel like an old-timey detective. whatever the case, a Murphy Bed is the furniture solution for outside-the-box sleepers!

In The Sims 3: University Life Sims get crushed by the Murphy bed more often, but those accidents rarely end up with death. Instead, Sims will get the Murphy Bed Clinophobia moodlet that will last for 6 hours, and during the time they have it they won't be able to close or pull down a Murphy bed.
