A modular seat apparatus comprising:

• a base;
• a seat, wherein the seat is moveably connected to the base such that the seat is rotatable relative to the base;
• a locking assembly associated with the seat, the locking assembly configured to lock the seat in one or more positions relative to the base;
• the locking assembly comprising a trigger that is manually actuable by a user;
• a plurality of accessories that are removably attachable to the seat, wherein the accessories comprise an armrest and a bench;
• the accessories being interchangeably attachable to the seat,
• in use, a first seat apparatus form created by attaching the armrest to the seat and a second seat apparatus form created by attaching the bench to the seat,
• wherein the seat is rotatable between an operative position and one or more other rotated positions, and the seat being lockable at the operative position and the one or more rotated positions by the locking assembly;
• wherein the armrest comprises a first locking assembly and the bench comprises a second locking assembly, each of the locking assemblies comprises a locking peg, a trigger in mechanical communication with the locking peg, and wherein the locking peg is biased toward a locking position to lock the seat relative to the base and the locking peg being moved to an unlocked position when the trigger is actuated;
• wherein the seat apparatus comprises a locking plate attached the base, a swivel plate attached to the seat, a bearing positioned between the locking plate and the swivel plate, the bearing rotatably coupling the swivel plate to the locking plate such that seat can rotate relative to the base.
