A cushioned seat is usually made up of two or three cushions. Since these cushions are made to support the weight of the sitter, they are usually firmer than back cushions. The cushions may be square or rectangular, depending on the number of cushions on the seat. Sometimes the end cushions are T-shaped to accommodate the arms. Cushioned seat covers typically are removable.
The back of a curved-back sofa curves all the way around so that it forms one solid piece with the arms, which are not attached separately. A pillow back sofa has more pillows than seat cushions, and therefore a softer feel. This style offers comfort that can also be adjusted by moving the pillows around. It does require more upkeep, though.
Seat cushions should be firm and resilient and fit snugly within the sofa frame. Additionally, the cushions should regain their shape after you press down and let go. A cushion that stays put when you press down will be flattened in no time, end up looking unsightly and feel uncomfortable when you sit on it. Cushions that do not fit snugly in place will also lose their shape quickly and the edges will start looking unsightly.
