Which mattress size is best for me?

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

• Personal sleeping space comfort
• Bedroom dimensions
• Size and quantity of furniture in bedroom

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.
