Seating

Throughout The Sims series, seating is a common furniture type of Buy mode object that can be found and purchased on any residential home (as well in community) lots. Different category of seating have their own distinguish purpose and appearance, though the common feature all hold is to allow Sims to sit or lie down on them.

In general, chairs are divided into three categories: dining chairs, living chairs or arm 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
Dining chairs, as the same suggest, are popular to be used for dining out on tables. However, they aren't limited to such funtion-wise scope and don't always necessary present in it appearances despite the classification. 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. 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 room, outdoor's and other seating
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. In The Sims 4, desk chairs are located in a seperate category.

A game may also include a 'misc' category, in which includes special-function of attribute chairs and those that in appearance don't fit any kind of categorization. These includes (but not limited) benches, outdoor seating, bar stools, or a makeover station.

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.
