Understanding the Mechanics of a Sleep Number Bed

For couples shopping for a new mattress, a bed that lets each person adjust their own side's comfort level could be worth considering.

The Sleep Number bed is like two beds in one.

When shopping for a new bed, couples might look for one that allows both partners to enjoy a restful night's sleep with individually tailored comfort. That is precisely what Select Comfort set out to achieve with the Sleep Number bed, which features an adjustable mattress so that each sleeper can lie on a section tuned to feel either firmer or softer.

How Air Chambers Replace Traditional Springs

Rather than using the coils or springs found in conventional mattresses, Sleep Number beds rely on air chambers. These chambers inflate or deflate to alter the mattress's firmness or softness. A remote control included with the bed lets users adjust the air chambers, enabling both occupants to get the level of support they prefer.

Separate Settings for Each Sleeper

Every Sleep Number bed comes with dual settings, meaning each person can use the remote to adjust the softness of their own half of the mattress. This proves especially useful for couples, as each individual can essentially "create" a mattress that suits them best. Certain Sleep Number models also include a feature known as FlexFit, an adjustable base that provides support for each person on the bed even while sitting up.

What Determines Your Sleep Number

A person's sleep number is influenced by several factors, with values ranging from one to 100. The sleeping position a person uses plays a role in deciding how firm the mattress ought to be; for example, someone who sleeps on her stomach might prefer a softer mattress, whereas her husband, who sleeps on his back, could favor a firmer one. A person's weight and height can also affect how soft or firm the Sleep Number bed should be.

Accessories That Complement the Sleep Number Bed

Beyond the bed itself, a variety of accessories can improve the sleeping experience. For instance, four Comfort Fit comforters are available for the bed, each growing softer and warmer as the number increases. Select Comfort's Pillow Fit technology lets buyers personalize their pillows by inserting foam or goose down to achieve the softness and support they want. Sleep Number mattress pads add to the bed's comfortable feel, and some models double as an electric blanket to warm the bed.
