A chair is a piece of furniture designed for a person to sit on. It usually has a horizontal surface, the seat, which supports the human buttocks from underneath. The seat, which is often padded for more comfort, is itself supported by 'legs', typically four of them, that have a height approximately equal to the lower leg, so that the person's feet will comfortably reach the ground when seated. The person's back is supported by another part of the chair which is also called the 'back', or 'backrest'. A chair that has no back is called a stool.
An optional part of a chair are armrests that support the seated person's forearms.
 Chairs as spanking furniture
In spanking art, chairs are particularly significant because it is common for a spanker to sit on a chair (typically an upright-back unpadded armless chair) to take a spankee over the spanker's lap for an OTK spanking. It is also common for a spankee to bend over and grasp the seat of a chair for a strapping, paddling, cropping, or caning. Less common, but still fairly common, is for the spankee to bend over the back of a chair. In both cases the buttocks of the spankee are elevated and presented for the spanking.
- The over-the-knee position (spanker seated on the chair)
- The hands-on-chair position (spankee standing, hands placed on the seat)
- The bent-over-object position (spankee's torso laid over the seat, with or without the spankee kneeling on the floor)
- The kneeling-in-a-chair position (spankee kneeling in the chair)
- The bending-over-back-of-chair position (spankee standing and bending over the chair back)

Another, more exotic, way in which chairs can be used as an item of spanking furniture involves two chairs which are placed back to back. The spankee then kneels on the seat of one chair (preferrably the chair is padded or a cushion is put on the seat to kneel on) and bends over the two backs, placing his/her hands (or elbows) on the other chair's seat so that his/her buttocks are raised to an exposed position, convenient for spanking. This is, in a way, a variant of the on-all-fours position with the help of two chairs that prevent the spankee from moving out of position.
Chairs are mainly used for domestic spanking (including home-like institutions such as orphanages), and to a lesser degree, in school spanking. They are not commonly used in judicial corporal punishment, prison corporal punishment, and military corporal punishment.
Among spankophiles, chairs are probably the most popular items of spanking furniture (next to beds and couches) because of their domestic spanking connotations and ready availability in every home. A chair or stool gives better support for the classic OTK spanking position than a couch or armchair which is usually lower and in which the spanker will sink in too much.
Armrests make a chair unsuitable for most spanking positions, so spankophiles generally prefer chairs without armrests.
 Sitting in a chair for punishment and lecture
It is also common for a spankee to be made to sit in a chair, often on a bare bottom, after a spanking, as a form of further punishment. Often this is a variation on corner time. Someone may also be directed to sit in an isolated chair as a form of time-out before or instead of a spanking.
When a chair is used in the 'pre-spanking' time-out way, it will have a very strong impact in the mind of the spankee because being told to sit on the chair means that he is in serious troubles.
There is often one special place where a punishment session always happens. It is that chair used for this. It is the favorite chair used by the spanker to enhance his authority figure.
Being told to sit in the chair means things such as: Think on what you did and later we will talk.
The chair can also be the place in which the spankee will listen to the unavoidable lecture. While still seated in the chair, the spankee can try arguing to avoid the spanking. The command "Get on your feet" means that the arguments and dialog didn't work. Getting up, in this situation, means to give the chair over to the spanker who will then sit down himself and take the spankee over his lap for an OTK spanking.
The chair can also be the place where the spankee will go back to sit down after the spanking and see if he was forgiven. Sometimes to cry and sometimes to reconciliate his feelings towards the spanker while feeling the sting getting stronger by sitting on the chair.
In the OTK position, the chair is one of the few things that the spankee can see besides the floor or the shoes of the spanker - the spankee is able to open his eyes.
