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 frame and all the corners should be well padded. Run your hand over them firmly to see. A padded frame will not stick out through the upholstery, it also means less friction for the fabric that is covering the frame. Check the sofa from behind, and pat the center to make sure it isn't hollow.
A camel back is a traditional sofa back that is shaped much like a camel‘s hump, raised in the middle, and sloping down lower at the ends. It often imparts a formal look. Deep vertical grooves on a tight back are the distinguishing features of a channel back. Loose cushions are separate from the sofa back, as opposed to attached back sofas. This allows for covers to be easily removed for cleaning.
