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.
If the sofa has any metal parts, inspect to see that they are smooth and free of sharp edges. All moving parts on a sofa bed or reclining sofa should clear the fabric completely to avoid tearing. You don't want any injuries to yourself or damage to your upholstery from a faulty mechanism. When you check out the back of your sofa, there should be no bumps or hard spots. Run the palm of your hand over it. This is especially important in a tight back sofa. Not only will bumps and hard spots mar the look of your sofa over a short period of time, they will also feel uncomfortable.
A very common traditional shape for sofa arms, a rolled arm curves outward. Although comfortable for lounging and reading, rolled arms do take up extra space and should be taken into account when measuring a sofa. A Lawson arm is a low-profile, modestly scaled version of the rolled arm.
