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.
An English arm is low and is set back from the front edge of the seat. English arms are low-profile and suitable if you like to take naps on your sofa. They are also good for small spaces, as they don‘t project beyond the body of the sofa. The front part of a pleated sofa arm is covered by fabric that is continued from the inside of the arm.
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.
