Seat extension furniture for aircraft seats

A surface extension system, comprising:

• secondary furniture, positioned proximal to a seat configured to be oriented in a sitting position, a slouched position, or a berthed position, wherein the secondary furniture comprises:
• a support structure, the support structure configured to raise a height of the secondary furniture to a height of the seat;
• a top surface;
• a pivot, wherein the pivot is configured to couple the support structure and the top surface, wherein the pivot permits the top surface to rotate about the pivot in order to match the orientation of the seat in any of the sitting position, the slouched position, or the berthed position;
• and
• a locking mechanism, wherein when the locking mechanism is engaged the locking mechanism prevents rotation of the top surface about the pivot and when the locking mechanism is disengaged the locking mechanism allows rotation of the top surface about the pivot;
• and
• an armrest, wherein a height of the armrest is adjustable to correspond with the seat in any of the sitting position, the slouched position, or the berthed position, wherein the armrest comprises:
• an armrest top surface;
• an armrest pivot, wherein the pivot permits the armrest to rotate about the armrest pivot in order to match the orientation of the seat in any of the sitting position, the slouched position, or the berthed position;
• and
• an armrest locking mechanism, wherein when the armrest locking mechanism is engaged the armrest locking mechanism prevents rotation of armrest about the armrest pivot and when the armrest locking mechanism is disengaged the armrest locking mechanism allows rotation of the armrest about the armrest pivot.
