Bed

Beds are objects in The Sims that increase a Sim's energy, comfort and decrease stress. Both single and double beds can be found in buy mode under "Bedroom" or "Comfort". Cribs serve the same purpose for babies and toddlers in The Sims 2 and The Sims 3. In The Sims 4, babies use a bassinet and toddlers use special toddler beds. They can be found under "Kids". Single beds will only fit one Sim, while a double bed can fit two, but the two Sims will only sleep together if they have a good relationship. Kids will sleep together regardless, although they will not sleep together if one or the other is in their undies.

Price
Beds come in a range of prices from cheap to expensive. In general, more expensive beds do a better job of restoring energy and comfort. Also in The Sims 3 and The Sims 4, sleeping in cheap beds will sometimes give Sims negative moodlets when they wake up.

In The Sims Life Stories, there is a §9,000 bed that is only unlocked in story rewards for Riley. This bed is called the "Fertillinator", and will increase the chance of success when trying for a baby.

Interactions
In The Sims 2, Sims can "Relax" on a bed, and will often do so autonomously.

In The Sims 2, The Sims 3, and The Sims 4, double beds are one of the objects in which Sims can WooHoo or try for a baby.

In The Sims 3: Supernatural, children can check for monsters under a bed during nighttime. There's a 60% chance that they will see glowing red eyes or a monster's arms sticking out, which will give them "Monsters Under the Bed" moodlet, and possibly "Terrified" moodlet, which is more likely to be gained if Sims have the coward, neurotic, easily impressed, or supernatural skeptic traits. While having the "Monsters Under the Bed" moodlet, children will not sleep on the bed the monster is from. Children will not get the moodlet if they have the "Someone to Watch Over Me" moodlet, which is gained by being promised protection by older Sims who are on the same lot. On the other hand, if the children don't find any monsters under the bed, they will get "No Monsters" moodlet, which will boost their energy need while sleeping.

Monsters return to The Sims 4 with Patch 36, in which they will spontaneously wake children up, giving them an uncomfortable moodlet that prevents them from sleeping for a while. They can be warded off by spraying monster repellent or installing the "Defender" lamp in the room. Sims may also attempt to befriend the monster.

Single Bed
Single bed is one of the two main types of beds in The Sims series. One single bed has a size of 1x3 and will only fit one Sim.

Double Bed
Double bed is one of the two main types of beds in The Sims series. A Double bed can fit two, but the two Sims will only sleep together if they have a good relationship. Kids will sleep together regardless, although they will not sleep together if one or the other is in their undies.

Bunk Bed

 * The Sims 3: Generations includes bunk beds, which can be used by kids and up.
 * The Sims Online was the first game overall to feature bunk beds, but Generations is the first expansion in the main series to include them.
 * Sometimes, Sims who wake up in the top bunk can be very daring and jump off.
 * Bunk beds are currently exclusive to The Sims 3, but a few custom content creators for The Sims, The Sims 2 and The Sims 4 have made working ones for those games.

Murphy Bed
The Murphy bed is a type of bed introduced in The Sims 2: Apartment Life and reintroduced in The Sims 3: University Life. The bed folds into the wall to save space. Unlike double beds, it takes a 2x4 size, with the extra space to folds the bed.

However, unlike real-life Murphy beds, the space used by an opened bed is still considered to be in use when the bed is closed. While Sims are able to walk through that space, objects cannot be placed in that space without using the moveobjects cheat.

Fertillinator
In The Sims Life Stories, there is a §9,000 bed that is only unlocked in story rewards for Riley. This bed is called the "Fertillinator", and will increase the chance of success when trying for a baby.

Vampiric Sanctum
The Sims 3: Late Night added a new type of bed, the Vampiric Sanctum. This bed is in the shape of a coffin and can only be used by vampires. At one end of the bed there is a bottle of sunscreen lotion and a cracked mirror. There is also a picture of the The Magical Freezer Bunny on the front end and a moon on the bottom end. Vampires will receive the "Slept Like the Dead" moodlet from using this bed.

Hover Bed

 * The Sims 3: Generations added Hover Bed as a Lifetime reward. It is a floating double bed for the Sim which gives them an additional +10 moodlet.
 * The Sims 4: Get Famous introduced a Sleeping Pod. Similar to a Hover Bed, it can float. However, its functions is more similar to the Dream Pod.

Dream pod

 * The Sims 3: Into the Future added a new special bed, called a Dream pod. Unlike other beds, the Dream Pod can change a Sim's life by providing a unique dream, which grants the Sim special effects when they wake up.
 * The Sims 4: Get Famous introduced a Sleeping pod, similar to a Dream pod. Although being a single bed, a Sleeping pod takes a 2x3 size.
