About Sleep Number
The company launched as Select Comfort in 1987 and renamed itself Sleep Number after its best-known feature: an air chamber whose pressure you set to a number, adjustable independently on each side of the bed.
Older directory listings often appear under Select Comfort or the Personal Preference collection sold through partner retailers; current models are the Classic, Performance, and Innovation series, plus smart beds with sleep tracking.
The appeal is adjustability, especially for couples with very different firmness needs or people whose comfort changes with pregnancy, injury, or age. The trade-offs are price, mechanical complexity, and a feel that never quite matches a good coil or latex bed.
What they make
Adjustable air-chamber beds with optional sleep tracking; adjustable bases; pillows and bedding.
Origin
American — manufactured in US plants
Sleep Number Signature Technologies
Sleep Number Setting
Air chambers inflate or deflate to a numeric firmness setting, adjustable independently on each side of the bed.
DualAir / Dual-Chamber Design
Separate chambers per side so partners can choose different firmness without a split mattress.
SleepIQ Tracking
Built-in sensors on smart models that report sleep duration and movement without a wearable.
Best for
- Couples with sharply different firmness preferences
- People whose comfort needs change — pregnancy, injury, recovery
- Buyers who want built-in sleep tracking without a wearable
- Anyone who wants to adjust firmness rather than commit to one feel
Not ideal for
- Buyers who dislike mechanical parts in a mattress
- Value shoppers — prices run high for the materials involved
- Sleepers who want the surface feel of a quality coil or latex bed

Sleep Number FAQ
Is Sleep Number the same as Select Comfort?
Yes. The company was founded as Select Comfort in 1987 and later renamed to Sleep Number, which is why older listings and the Personal Preference collection appear under the Select Comfort name.
Are Sleep Number beds worth it?
They are worth it if adjustable, per-side firmness solves a real problem for you — mismatched partners, changing needs, recovery from injury. If you simply want a comfortable mattress, comparable money buys a better-built hybrid or latex bed.
What can go wrong with an air bed?
The air chambers, pump, hoses, and remote are mechanical components that can fail or leak. Most owners get years of trouble-free use, but it is a maintenance profile a conventional mattress does not have.
Can couples set different firmness?
Yes — dual-chamber models let each side be set independently, which is the brand's core advantage over split-firmness foam mattresses.
