Experts and SLEEP NUMBER alike recommend buying the largest size bed that will fit in your bedroom. Many factors help determine which size bed is best for you. Some include:Personal sleeping space comfort
Choosing the right size of bed is important, especially when buying a Sleep Number bed, which will last at least 20 years! As a general guideline, choose a bed that is at least 4 inches longer than the height of the tallest sleeper and wide enough so that each sleeper can comfortably rest without overlapping his/her sleeping partner.
