忌背門而坐, back to the door
Never Sit With Your Back to the Door
In feng shui the doorway is the mouth of the room, 氣口, where energy enters. Sit with your back to it and the tradition says you lose your footing. See the door, or sit in a solid high-backed chair.
The short answer
Why sitting with your back to the office door is bad feng shui
In feng shui the doorway is the mouth of the room, 氣口 (qì kǒu), where energy enters. Sit with your back to it and the tradition says you lose your footing: you cannot see who comes in, movement gathers behind you, and part of your attention stays turned around all day. The old fix is simple. See the door, or sit in a solid high-backed chair.
The tradition
The taboo of the turned back
The Chinese name for this is 忌背門而坐 (jì bèi mén ér zuò), the taboo of sitting with your back to the door. Everything a room breathes comes through that one opening. The living, gathering kind, 生氣 (shēng qì), and the sharp, rushing kind, 煞氣 (shā qì), both arrive at the same threshold, and the seat that cannot read the threshold is the seat feng shui warns against.
Put your back to it and the door keeps working without you. People pass. A shape crosses the light. You feel it before you understand it, and a thin thread of your focus stays behind you where you cannot look. Practitioners give this its own name, 冷風吹背 (lěng fēng chuī bèi), cold wind blows the back, the sense of an exposed spine in a room that moves.
Old texts push the image further and tie the exposed back to aches and the kidneys. We name that only as an old belief. It is not health advice, and nothing about where a chair sits treats or prevents any condition.
Honest note
Ordinary sense and symbol
Part of this needs no talk of qi. A back to an open door, in ordinary experience, is a back to the unknown, and the small startle when someone appears without warning is real and tiring over a working day. Face the door and that particular pull lets go. The rest, the qi-mouth and the cold wind, is symbolic tradition, offered for reflection and not as measured fact.
In practice
How to arrange it
Move the desk first. The prize is a seat that takes in the doorway on a diagonal, off to one side, so you notice an arrival with a glance and never sit square in the line the door fires down. A wall behind the chair completes it. When the room fights you and the door has to stay at your back, a tall solid-backed chair stands in for the wall you lack, and a small mirror placed to show the doorway returns what you cannot see. Keep the space between you and the door open and uncluttered, so what enters has room to settle before it reaches your seat.
Your animal in this seat
The seat where your direction comes to bear
Your Primal Animal carries a home direction and a Kua number, and the seat is where both come to bear. In the Eight Mansions method, 八宅 (bā zhái), your birth year and sex place you in the East group or the West group and hand you four favorable directions. A Rat animal like the Coconut Crab leans north, its own branch, 子; a Horse animal like the Kea leans south, 午; a Rooster crossing such as the Emperor Penguin leans west, 酉. Turn the chair so it faces the door and, where the room allows, angle it toward one of your favorable directions at the same time. Which direction is yours shifts with your Kua, so an East-group animal such as the Moon Bear and a West-group one will not settle on the same wall.
The seat that cannot see the door is the seat that never fully sits down.

Common questions
Questions people ask
What if my desk can only face away from the door?
Take a high-backed chair with a solid, unbroken back, sit it close against a wall, and set a small mirror where it shows the doorway. In feng shui the tall back stands in for a wall, and the mirror gives you the door your seat cannot.
Does the door being open or closed change it?
The tradition reads the doorway itself as the qi-mouth, open or shut, so the seating rule holds either way. In ordinary terms a closed door removes the moving shapes and eases the pull a little, but it does not undo a back turned to the room's one entrance.
Is a window the same as a door behind me?
Close, but not identical. A door admits people and traffic; a window admits light, sound, and exposure. Each earns its own caution, covered in window behind you and a walkway window.
