One curve, held by two plates.
Start at the top of the back and follow it around. It is one padded shell that curves from one side of the seat to the other, and its top edge slopes down towards the front.
Below the shell, a wide arch stays open. A strip of the room shows through between the back and the seat.
On each side, one flat black metal plate joins the shell to the seat with two bolts. Four tapered legs take it to the floor.
