Sleep is something that affects every aspect of your life. If you aren't getting enough sleep or high-quality sleep, your work life, health, relationships, and more are sure to suffer. Aside from mustering up the self-discipline to get to bed at a reasonable hour, you may also be shopping around for a new mattress. The quality of your mattress can greatly affect the quality of your sleep. With a decision this big, you don't want to do it on impulse alone.
