Vibromatic Heart Bed

The Sims
The Vibromatic Heart Bed, introduced in The Sims: Livin' Large, gives your Sims the opportunity to "play" in bed. Send a Sim to turn the bed to 'Vibrate' and have that Sim lie in bed. Then, send a loved one to play in bed. Then they "play", with their Fun and Social meters rising. However, one side effect of this activity is a baby appearing. This action could even be performed between homosexual couples with an immense amount of difficulty with the rising relationship. However in this case a baby would not appear. One way to make no baby appear is if you use cheats to turn the skin of the couple using the bed have skin textures the game can not compute, therefore the baby will not compute. THIS MAY NOT WORK ON ALL COPIES OF THE GAME

The Sims 3: High-End Loft Stuff
The Vibromatic Heart Bed is reintroduced in The Sims 3 with the first stuff pack, The Sims 3: High-End Loft Stuff. More informations and photos will come when the stuff pack will be released.

Cheat
There was one cheat commonly used when sims were performing ths action in bed. If the player engaged the "Move_objects on" cheat and moved the bed to a separate part of the lot. The player could then see the sims basically naked and hugging while suspended in mid-air. It gave the Illusion of them lying on the ground. A humorous side-effect to the event. When the sims had completed their routine, if their energy was high enough they would climb out of the bed wherever it was placed on the lot.
