Summarize the following:
It's extra important to have a comfortable, supportive mattress if you have scoliosis. For most individuals, a medium to firm mattress is the best choice, although it's most important that you are comfortable. Memory foam may not be the right choice for people with scoliosis, as it does not always provide as much support as a traditional mattress. Many people who have scoliosis do not have the proper amount of curvature in their necks and low backs. Try sleeping on a cervical pillow and a lumbar roll to help encourage your spine to curve in a healthy way. A single pillow or roll is preferable to multiple pillows. Sleeping on a stack of pillows can be harmful. If you have a brace to correct the curvature in your spine, it's important that you wear it as much as your doctor tells you to. Most patients are supposed to wear their braces 21 hours or more each day, which means they must keep them on at night.

Summary:
Invest in a good mattress. Use supportive pillows. Follow your doctor's instructions about wearing your brace.
