Vibromatic Heart Bed

The Vibromatic Heart Bed, introduced in The Sims: Livin' Large and returned in The Sims 3: High-End Loft Stuff, is a double bed with a heart-shaped headboard.

The Sims
The Vibromatic Heart Bed, introduced in The Sims: Livin' Large, gives Sims the opportunity to "play" in bed.

To play, 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. If the Sims are of opposite genders, the "Should we have a baby?" question may appear. However, it is possible that a baby will appear spontaneously after Sims "play" in this bed, or in custom beds cloned from it. While that isn't supposed to happen, it has been known to happen. Same-sex couples can "play in bed", though that will not produce a baby.

Using the "Vibrate" interaction on the Vibromatic Heart Bed costs §20, though many custom beds based on it were modified so that they did not charge.

If The Sims: Vacation is installed, the Vibromatic Heart Bed can be placed on Vacation Island lots.

The Sims 2
The More Romantic than You Double Bed, which resembles the Vibromatic Heart Bed, appears in The Sims 2: Apartment Life.

The Sims 3
The Vibromatic Heart Bed is reintroduced in The Sims 3 with the first stuff pack, The Sims 3: High-End Loft Stuff. It gives 3 energy, so it is not the best bed to sleep in regularly, however it considerably raises the odds of conceiving a baby.

The bed regains its name from The Sims, however there a few noticable design differences.

Cheat
There was one cheat commonly used when Sims were performing this 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 nude and hugging while suspended in mid-air. 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.
