Correct posture does wonders for sore backs. Thing is, if a person isn’t accustomed to maintaining proper alignment of the spine, they tend to slouch. Not with the proper cushions, though. A variety of pillows and pads help support the spine. These portable cushions can be used at home or at work. An adjustable lumbar support cushion is especially helpful when driving, because car seats are notoriously bad for people with sore backs.
