Seating

A chair is a type of Buy mode object that has appeared throughout The Sims series that allows Sims to sit or lie down. Some objects, such as computers and chess sets, cannot be used unless a chair is present. In The Sims and The Sims 2, chairs fill the comfort motive. In The Sims 3, they give the "Comfy" moodlet.

In general, chairs are divided into three categories: dining chairs, living chairs, sofas/loveseats, and recliners, though not all games use the same category names. Such objects, along with Beds category, are classified as "comfort" in buy mode under Sort by function. The Label is given likely due to the fact that all these furniture objects originally have the purpose of increasing one's comfort motive.

Dining chairs are designed to be used in front of objects, such as dining tables, desks, and chess sets, that Sims use while sitting. They are generally animated so that Sims can slide them back from, and back to, what they are in front of, which adds realism. Therefore, office-style chairs are often grouped as dining chairs. Living chairs generally appear more solid and substantial. They're the sort of chairs a Sim might sit in to read or watch television. Loveseats can seat up to two Sims, while sofas can seat two or more. Sims can nap or lounge on them, and will automatically converse with other Sims seated on the same couch or in nearby seats. They can also sometimes perform romantic and non-romantic interactions with any Sim seated adjacent to them. Recliners can be used as living chairs, but Sims can also nap in them.

Toddlers can be put in a high chair, which is equivalent to a dining chair older Sims can use. High chairs come with their own eating surface, so they do not need to be placed in front of a table. High chairs are not required, but can make it easier to feed toddlers, and allows Sims to serve baby food to them. Toddlers cannot get out of a high chair until an older Sim lets them out.

The Sims 2
Objects are divided into dining chairs, armchairs, recliners, sofas and miscellaneous. Desk chairs are found under dining ones. Recliners category also feature lounges. Benches, bar stools and a makeover station are located in th miscellaneous category.
