Rim around the bed: the better to trip over and bash your shins on.
Chairs that you can't get any kind of back support from yet they take up space and have sharp corners.
Tiny coffee table set too low to the ground-- why not just put your shit on the floor and be done with it?
Concrete walls so that you have absolutely no reason to lean on them or touch them.
Fuck, there's absolutely no reason at all to be in this room.
It's like the whole thing was specifically designed to be as uncomfortable as possible. It's like a room that induces a kind of state of mental diarrhea where you feel an urgent need to leave the room and go somewhere else to get relief.
